Blackstone is acquiring mobile ad company Vungle

Posted by | artificial intelligence, Blackstone, Fundings & Exits, M&A, Mobile, Private Equity, vungle | No Comments

Private equity firm Blackstone just announced that it has reached an agreement to acquire mobile advertising company Vungle.

The companies aren’t disclosing the financial terms, but as part of the transaction, Vungle has also reached a settlement with founder Zain Jaffer, who filed a wrongful termination lawsuit against the company earlier this year.

(Update: Multiple sources with knowledge of the deal said that the acquisition price was around — or north of — $750 million. One of those sources also said it was an all-cash transaction.)

“As a best-in-class performance marketing platform, Vungle represents a key growth engine for the mobile app ecosystem,” said Blackstone principal Sachin Bavishi in a statement. “Our investment will help deliver on the company’s tremendous growth potential and we look forward to partnering with management to extend Vungle’s strength across mobile gaming and other performance brands.”

Meanwhile, CEO Rick Tallman said the deal will allow the company to “further accelerate Vungle’s mission to be the trusted guide for growth and engagement, transforming how users discover and experience mobile apps.”

Vungle was founded back in 2011, and, according to the acquisition release, it’s currently working with 60,000 mobile apps worldwide, serving more than 4 billion video views per month and working with publishers like Rovio, Zynga, Pandora, Microsoft and Scopely.

Jaffer led Vungle as CEO until October 2017, when he was arrested on charges including performing a lewd act upon a child and assault with a deadly weapon. The charges were ultimately dropped, with the San Mateo County District Attorney’s office stating that it did “not believe that there was any sexual conduct by Mr. Jaffer that evening,” while “the injuries were the result of Mr. Jaffer being in a state of unconsciousness caused by prescription medication.”

In his lawsuit, Jaffer alleged that after the charges were dropped, “Vungle unfairly and unlawfully sought to destroy my career, blocked my efforts to sell my own shares or transfer shares to family members, and tried to prevent me from purchasing shares in the Company.”

In a statement today, Jaffer said, he is “pleased with the terms of the settlement, which are confidential.” He also commented on the acquisition:

It is extremely gratifying for me to see our early vision, execution and the hard work of so many talented people rewarded like this. From Day 1, Vungle has been at the forefront of the changing advertising landscape. Today, companies of all sizes, and in all industries, are utilizing in-app video ads as an integral part of their customer acquisition strategies.

The acquisition is expected to close later this year. According to Crunchbase, Vungle previously raised more than $25 million from Crosslink Capital, Thomvest Ventures, Seven Peaks Ventures, GV, AOL Ventures, Uncork Capital, 500 Startups and Angelpad, where the startup was incubated. (AOL Ventures was backed by TechCrunch’s parent company AOL, a.k.a. Oath, a.k.a. Verizon Media.)

VidCon, the annual summit in Anaheim, CA for social media stars and their fans to meet each other drew over 75,000 attendees over last week and this past weekend. A small subset of those where entertainment and tech executives convening to share best practices and strike deals.

Of the wide range of topics discussed in the industry-only sessions and casual conversation, five trends stuck out to me as takeaways for Extra Crunch members: the prominence of TikTok, the strong presence of Chinese tech companies in general, the contemplation of deep fakes, curiosity around virtual influencers, and the widespread interest in developing consumer product startups around top content creators.

Newer platforms take center stage

TikTok, the Chinese social video app (owned by Bytedance) that exploded onto the US market this past year, was the biggest conversation topic. Executives and talent managers were curious to see where it will go over the next year more than they were convinced that it is changing the industry in any fundamental way.

TikTok influencers were a major presence on the stages and taking selfies with fans on the conference floor. I overheard tweens saying “there are so many TikTokers here” throughout the conference. Meanwhile, TikTok’s US GM Vanessa Pappas held a session where she argued the app’s focus on building community among people who don’t already know each other (rather than being centered on your existing friendships) is a fundamental differentiator.

Kathleen Grace, CEO of production company New Form, noted that Tik Tok’s emphasis on visuals and music instead of spoken or written word makes it distinctly democratic in convening users across countries on equal footing.

Esports was also a big presence across the conference floor with teens lined up to compete at numerous simultaneous competitions. Twitch’s Mike Aragon and Jana Werner outlined Twitch’s expansion in content verticals adjacent to gaming like anime, sports, news, and “creative content’ as the first chapter in expanding the format of interactive live-streams across all verticals. They also emphasized the diversity of revenue streams Twitch enables creators to leverage: ads, tipping, monthly patronage, Twitch Prime, and Bounty Board (which connects brands and live streamers).

Facebook’s testimony to Congress: Libra will be regulated by Swiss

Posted by | Apps, blockchain, Calibra, Congress, cryptocurrency, David Marcus, eCommerce, Facebook, Finance, Government, house of representatives, Libra, Libra Association, Mobile, payments, Personnel, Social, TC, U.S. Senate | No Comments

The head of Facebook’s blockchain subsidiary Calibra David Marcus has released his prepared testimony before Congress for tomorrow and Wednesday, explaining that the Libra Association will be regulated by the Swiss government because that’s where it’s headquartered. Meanwhile, he says the Libra Association and Facebook’s Calibra wallet intend to comply will all U.S. tax, anti-money laundering and anti-fraud laws.

“The Libra Association expects that it will be licensed, regulated, and subject to supervisory oversight. Because the Association is headquartered in Geneva, it will be supervised by the Swiss Financial Markets Supervisory Authority (FINMA),” Marcus writes. “We have had preliminary discussions with FINMA and expect to engage with them on an appropriate regulatory framework for the Libra Association. The Association also intends to register with FinCEN [The U.S. Treasury Department’s Financial Crimes Enforcement Network] as a money services business.”

Marcus will be defending Libra before the Senate Banking Committee on July 16th and the House Financial Services Committees on July 17th. The House subcomittee’s Rep. Maxine Waters has already issued a letter to Facebook and the Libra Association requesting that it halt development and plans to launch Libra in early 2020 “until regulators and Congress have an opportunity to examine these issues and take action.”

The big question is whether Congress is savvy enough to understand Libra to the extent that it can coherently regulate it. Facebook CEO Mark Zuckerberg’s testimonies before Congress last year were rife with lawmakers dispensing clueless or off-topic questions.

Sen. Orin Hatch infamously demanded to know “how do you sustain a business model in which users don’t pay for your service?,” to which Zuckerberg smirked, “Senator, we run ads.” If that concept trips up Congress, it’s hard to imagine it grasping a semi-decentralized stablecoin cryptocurrency that took us 4,000 words to properly explain, and a six-minute video just to summarize.

Attempting to assuage a core concern that Libra is trying to replace the dollar or meddle in financial policy, Marcus writes that “The Libra Association, which will manage the Reserve, has no intention of competing with any sovereign currencies or entering the monetary policy arena. It will work with the Federal Reserve and other central banks to make sure Libra does not compete with sovereign currencies or interfere with monetary policy. Monetary policy is properly the province of central banks.”

Marcus’ testimony comes days after President Donald Trump tweeted Friday to condemn Libra, claiming that “Unregulated Crypto Assets can facilitate unlawful behavior, including drug trade and other illegal activity. Similarly, Facebook Libra’s ‘virtual currency’ will have little standing or dependability. If Facebook and other companies want to become a bank, they must seek a new Banking Charter and become subject to all Banking Regulations, just like other Banks, both National and International.”

TechCrunch asked Facebook for a response Friday, which it declined to provide. However, a Facebook spokesperson noted that the Libra Association won’t interact with consumers or operate as a bank, and that Libra is meant to be a complement to the existing financial system.

Regarding how Libra will comply with U.S. anti-money laundering (AML) and know-your-customer (KYC) laws, Marcus explains that “The Libra Association is similarly committed to supporting efforts by regulators, central banks, and lawmakers to ensure that Libra contributes to the fight against money laundering, terrorism financing, and more,” Marcus explains. “The Libra Association will also maintain policies and procedures with respect to AML and the Bank Secrecy Act, combating the financing of terrorism, and other national security-related laws, with which its members will be required to comply if they choose to provide financial services on the Libra network.”

He argues that “Libra should improve detection and enforcement, not set them back,” because cash transactions are frequently used by criminals to avoid law enforcement. “A network that helps move more paper cash transactions—where many illicit activities happen—to a digital network that features regulated on- and off-ramps with proper know-your-customer (KYC) practices, combined with the ability for law enforcement and regulators to conduct their own analysis of on-chain activity, will present an opportunity to increase the efficacy of financial crimes monitoring and enforcement.”

As for Facebook itself, Marcus writes that “The Calibra wallet will comply with FinCEN’s rules for its AML/CFT program and the rules set by the Office of Foreign Assets Control (OFAC) . . . Similarly, Calibra will comply with the Bank Secrecy Act and will incorporate KYC and AML/CFT methodologies used around the world.”

These answers might help to calm finance legal eagles, but I expect much of the questioning from Congress will deal with the far more subjective matter of whether Facebook can be trusted after a decade of broken privacy promises, data leaks and fake news scandals like Cambridge Analytica.

That’s why I don’t expect the following statement from Marcus about how Facebook has transformed the state of communication will play well with lawmakers that are angry about how those changes impacted society. “We have done a lot to democratize free, unlimited communications for billions of people. We want to help do the same for digital currency and financial services, but with one key difference: We will relinquish control over the network and currency we have helped create.” Congress may interpret “democratize” as “screw up,” and not want to see the same happen to money.

Facebook and Calibra may have positive intentions to assist the unbanked who are indeed swindled by banks and money transfer services that levy huge fees against poorer families. But Facebook isn’t acting out of pure altruism here, as it stands to earn money from Libra in three big ways that aren’t mentioned in Marcus’ testimony:

  1. It will earn a share of interest earned on the Libra Reserve of traditional currencies it holds as collateral for Libra that could mount into the billions if Libra becomes popular.
  2. It will see Facebook ad sales grow if merchants seek to do more commerce over the internet because they can easily and cheaply accept online payments through Libra and therefore put marketing spend into those efficiently converting channels like Facebook and Google.
  3. It will try to sell additional financial services through Calibra, potentially including loans and credit where it could ask users to let it integrate their Facebook data to get a better rate, potentially decreasing defaults and earning Facebook larger margins than other players.

The real-world stakes are much higher here than in photo sharing, and warrant properly regulatory scrutiny. No matter how much Facebook tries to distance itself from ownership of Libra, it started, incubated and continues to lead the project. If Congress is already convinced “big is bad,” and Libra could make Facebook bigger, that may make it difficult to separate their perceptions of Facebook and Libra in order to assess the currency on its merits and risks.

Waze now shows road toll prices along your driving route

Posted by | Apps, Canada, crowdsourcing, Mobile, TC, transport, Transportation, United States, waze | No Comments

Navigation app Waze is making getting to where you’re going even easier — or at least more transparent. A new feature rolling out today will show you any tolls along your route, including the actual amount you’re going to pay, across both the U.S. and Canada.

This is above and beyond what you’ll get in most navigation apps, where you might get a visual or text indicator that there is a toll on one of the roads in your path (and you can opt to avoid them if possible) but you won’t know what you’re actually paying. With Waze, you’ll get the amount — sourced from its community of user-drivers, rather than direct from the official toll road operators — but Waze’s crowd-sourced navigation data often has a leg up on the official source in other cases.

Waze will show you the toll prices up front, too, before the navigation actually gets under way, which is great, because that’s when you actually have the opportunity to do something about it, whether it’s scrounging seat-cushion change or just choosing to drive a different way.

This will be rolling out beginning today, so keep an eye out if you’re trying to get somewhere in the U.S. or Canada.

No technical reason to exclude Huawei as 5G supplier, says UK committee

Posted by | 5g, Asia, Australia, China, cyber security, Ericsson, Europe, huawei, human rights, Ian Levy, Internet of Things, jeremy wright, Mobile, National Cyber Security Centre, national security, Nokia, privacy, Security, TC, telecommunications, United Kingdom, United States, zte | No Comments

A UK parliamentary committee has concluded there are no technical grounds for excluding Chinese network kit vendor Huawei from the country’s 5G networks.

In a letter from the chair of the Science & Technology Committee to the UK’s digital minister Jeremy Wright, the committee says: “We have found no evidence from our work to suggest that the complete exclusion of Huawei from the UK’s telecommunications networks would, from a technical point of view, constitute a proportionate response to the potential security threat posed by foreign suppliers.”

Though the committee does go on to recommend the government mandate the exclusion of Huawei from the core of 5G networks, noting that UK mobile network operators have “mostly” done so already — but on a voluntary basis.

If it places a formal requirement on operators not to use Huawei for core supply the committee urges the government to provide “clear criteria” for the exclusion so that it could be applied to other suppliers in future.

Reached for a response to the recommendations, a government spokesperson told us: “The security and resilience of the UK’s telecoms networks is of paramount importance. We have robust procedures in place to manage risks to national security and are committed to the highest possible security standards.”

The spokesperson for the Department for Digital, Media, Culture and Sport added: “The Telecoms Supply Chain Review will be announced in due course. We have been clear throughout the process that all network operators will need to comply with the Government’s decision.”

In recent years the US administration has been putting pressure on allies around the world to entirely exclude Huawei from 5G networks — claiming the Chinese company poses a national security risk.

Australia announced it was banning Huawei and another Chinese vendor ZTE from providing kit for its 5G networks last year. Though in Europe there has not been a rush to follow the US lead and slam the door on Chinese tech giants.

In April leaked information from a UK Cabinet meeting suggested the government had settled on a policy of granting Huawei access as a supplier for some non-core parts of domestic 5G networks, while requiring they be excluded from supplying components for use in network cores.

On this somewhat fuzzy issue of delineating core vs non-core elements of 5G networks, the committee writes that it “heard unanimously and clearly” from witnesses that there will still be a distinction between the two in the next-gen networks.

It also cites testimony by the technical director of the UK’s National Cyber Security Centre (NCSC), Dr Ian Levy, who told it “geography matters in 5G”, and pointed out Australia and the UK have very different “laydowns” — meaning “we may have exactly the same technical understanding, but come to very different conclusions”.

In a response statement to the committee’s letter, Huawei SVP Victor Zhang welcomed the committee’s “key conclusion” before going on to take a thinly veiled swiped at the US — writing: “We are reassured that the UK, unlike others, is taking an evidence based approach to network security. Huawei complies with the laws and regulations in all the markets where we operate.”

The committee’s assessment is not all comfortable reading for Huawei, though, with the letter also flagging the damning conclusions of the most recent Huawei Oversight Board report which found “serious and systematic defects” in its software engineering and cyber security competence — and urging the government to monitor Huawei’s response to the raised security concerns, and to “be prepared to act to restrict the use of Huawei equipment if progress is unsatisfactory”.

Huawei has previously pledged to spend $2BN addressing security shortcomings related to its UK business — a figure it was forced to qualify as an “initial budget” after that same Oversight Board report.

“It is clear that Huawei must improve the standard of its cybersecurity,” the committee warns.

It also suggests the government consults on whether telecoms regulator Ofcom needs stronger powers to be able to force network suppliers to clean up their security act, writing that: “While it is reassuring to hear that network operators share this point of view and are ready to use commercial pressure to encourage this, there is currently limited regulatory power to enforce this.”

Another committee recommendation is for the NCSC to be consulted on whether similar security evaluation mechanisms should be established for other 5G vendors — such as Ericsson and Nokia: Two European based kit vendors which, unlike Huawei, are expected to be supplying core 5G.

“It is worth noting that an assurance system comparable to the Huawei Cyber Security Evaluation Centre does not exist for other vendors. The shortcomings in Huawei’s cyber security reported by the Centre cannot therefore be directly compared to the cyber security of other vendors,” it notes.

On the issue of 5G security generally the committee dubs this “critical”, adding that “all steps must be taken to ensure that the risks are as low as reasonably possible”.

Where “essential services” that make use of 5G networks are concerned, the committee says witnesses were clear such services must be able to continue to operate safely even if the network connection is disrupted. Government must ensure measures are put in place to safeguard operation in the event of cyber attacks, floods, power cuts and other comparable events, it adds. 

While the committee concludes there is no technical reason to limit Huawei’s access to UK 5G, the letter does make a point of highlighting other considerations, most notably human rights abuses, emphasizing its conclusion does not factor them in at all — and pointing out: “There may well be geopolitical or ethical grounds… to enact a ban on Huawei’s equipment”.

It adds that Huawei’s global cyber security and privacy officer, John Suffolk, confirmed that a third party had supplied Huawei services to Xinjiang’s Public Security Bureau, despite Huawei forbidding its own employees from misusing IT and comms tech to carry out surveillance of users.

The committee suggests Huawei technology may therefore be being used to “permit the appalling treatment of Muslims in Western China”.

Petcube’s Bites 2 and Play 2 amuse pets and humans alike with Alexa built-in

Posted by | albums, cameras, Gadgets, hardware, laser, pet, petcube, products, Reviews, smart speakers, Sonos, sonos one, Speaker, TC | No Comments

Petcube’s original Bites smart treat dispenser and Play pet camera with a built-in laser pointer were great for pet parents who couldn’t always be around to hang out with their furry charges, but the new Bites 2 and Play 2 come with one big new upgrade that make them far more versatile than the original: They both double as Alexa-powered smart speaker devices.

Both the Bites 2 and Play 2 can hear and respond to Alexa requests, with a four-microphone array that in my limited testing actually outperforms the Alexa mics built into my Sonos One and Sonos Beam speakers, which is pretty impressive for devices whose main features are serving up treats and keeping an eye on your pets. That’s on top of the Bites 2 being able to remotely dispense treats for your pet, and the Play 2 providing playtime away from home with a built-in laser pointer you can direct from your phone.

The Bites 2 and Play 2 also feature other improvements, including new wider angle lenses that offer full 180-degree views of your home for more likelihood you’ll spot your pets wandering around, and better Wi-Fi connectivity support with additional 5GHz networking, plus night vision and full HD video. Currently, the field of view is limited to 160-degrees, with an update to follow that will unlock the full 180; for most users, the 160 FOV is going to show you an entire room and then some.

With the Bites 2, you can also initiate video calls and chat with your pet, though my dog Chelsea basically is just confused by this. It is handy if I need to ask my partner if there’s anything else I’m forgetting to pick up from the store, however. And the treat-flinging feature definitely does appeal to Chelsea, especially now that it’s Alexa-integrated so that I can easily issue a voice command to give her a well-earned reward.

This has actually proven more than just fun — Chelsea suffers from a little bit of separation anxiety, so when we leave our condo she usually spends a few quick minutes complaining audibly with some rather loud barks. But since getting the Petcube Bites 2 to test, I’ve been reinforcing good behavior by reminding her to keep quiet, waiting outside the door and then flinging her a treat or two for her troubles. It’s pretty much done away with the bye-bye barking in just a short time.

The Play 2 doesn’t fling treats, but it does have a built-in laser pointer (which the company says is totally safe for your pet’s eyes). Chelsea straight up does not understand the laser or even really acknowledge it, so that’s a bit of a miss, but with a friend’s cat this proved an absolute show-stopping feature. I’ve also known dogs previously who loved this, so your mileage may vary, but if you’re unsure, it’s probably worth picking up a dollar-store laser pointer keychain first to ensure it’s their jam.

The $249 Bites 2 and $199 Play 2 offer a ton of value in just the image and build quality upgrades over their original incarnations, and their basic features are probably plenty enough for doting pet parents. But the addition of Alexa makes these both much more appealing in my opinion, since it essentially bundles an Echo in each device at no extra cost.

Hero Labs raises £2.5M for its ultrasonic device to monitor a property’s water use and prevent leaks

Posted by | Earthworm Group, Europe, Gadgets, Hero Labs, Recent Funding, Startups, TC | No Comments

Hero Labs, a London-based startup that is developing “smart” technology to help prevent water leaks in U.K. properties, has raised £2.5 million in seed funding. The round is led by Earthworm Group, an environmental fund manager, with further support via a £300,000 EU innovation grant and a number of unnamed private investors.

The new capital will be used by Hero Labs to accelerate development of its first product: a smart device dubbed “Sonic” that uses ultrasonic technology to monitor water use within a property, including the early detection of water leaks.

Founded in 2018 by Krystian Zajac after he exited Neos, a smart home insurer that was acquired by Aviva, Hero Labs was born out of the realisation that a lot of smart home technology either wasn’t very smart or didn’t solve mass problems (Zajac had also previously run a smart home company focusing on ultra-high-net-worth individuals that delivered bespoke designs for things like motorised swimming pool floors or home cinemas doubling up as panic rooms).

Coupled with this, the Hero Labs founder learned that water wastage was a very costly problem, both financially and environmentally, with water leaks being the number one culprit for property damage in the U.K., ahead of fires, gas explosions or break-ins combined. This sees water leaks cost the U.K. insurance industry £1 billion per year, apparently.

“My vision for the company is to solve real-life problems with truly smart technology,” Zajac tells me. “From working at Neos and alongside some of the world’s largest home insurers I understood the problems that impacted ordinary homeowners and their families on a day-to-day basis. Perhaps most surprisingly, I learnt that water leaks are far and way the biggest cause of damage to homes… I also wanted to do more for the environment in my next venture after learning that water leaks waste 3 billion litres of water a day in the U.K. alone.”

KZ Event

To that end, the Sonic device and service is described as a smart leak defence system. Aimed at anyone who wants to prevent water leaks in their property — including homeowners, landlords, facilities management, property developers and businesses — the ultrasonic device typically attaches to the piping below your sink and “listens” to the vibrations coming off the interconnected pipes.

Sonic then monitors the water flow using machine learning and its algorithms to identify usage and detect anomalies. This requires the technology to understand the difference between appliances, running taps and even flushing toilets so that it can build up a picture of normal water usage in the home and in turn identify if that pattern is broken. Crucially, if needed, Sonic can automatically shut off the water supply to prevent a water leak from damaging the property or its possessions.

Will a full launch planned for later this year, Sonic is targeting consumers as well as small businesses initially. “We are [also] in discussions with insurers who might subsidise the product or give it away completely for free to certain more affluent customers to minimise the risk of water escape,” adds Zajac.

Archinaut snags $73 million in NASA funding to 3D-print giant spacecraft parts in orbit

Posted by | 3d printing, Archinaut, Gadgets, hardware, Made In Space, Space, TC | No Comments

A project to 3D-print bulky components in space rather than bring them up there has collected a $73.7 million contract from NASA to demonstrate the technique in space. Archinaut, a mission now several years in development from Made In Space, could launch as soon as 2022.

The problem at hand is this: If you want a spacecraft to have solar arrays 60 feet long, you need to bring 60 feet of structure for those arrays to attach to — they can’t just flap around like ribbons. But where do you stash a 60-foot pole, or two 30-foot ones, or even 10 six-foot ones when you only have a few cubic feet of space to put them in? It gets real complicated real fast to take items with even a single large dimension into space.

Archinaut’s solution is simple. Why not just take the material for that long component into space and print it out on the spot? There’s no more compact way to keep the material than as a brick of solid matter.

Naturally this extends (so to speak) to more than simply rods and poles — sheets of large materials for things like light sails, complex interlocking structures on which other components could be mounted… there are plenty of things too big to take into space in one piece, but which could be made of smaller ones if necessary. Here’s one made for attaching instruments at a large fixed distance from a central craft:

optimast3Made in Space already has contracts in place with NASA, and has demonstrated 3D printing of parts aboard the International Space Station. It has also shown that it can print stuff in an artificial vacuum more or less equivalent to a space environment.

The demonstrator mission, Archinaut One, would launch aboard a Rocket Lab Electron launch vehicle no earlier than 2022, and after achieving a stable orbit, begin extruding a pair of beams that will eventually extend out 32 feet. Attached to these beams will be flexible solar arrays that unfurl at the same rate, attached to the rigid structures of the beams. When they’re finished, a robotic arm will lock them in place and do other housekeeping.

You can see it all happen in this unfortunately not particularly exciting video:

Once finished, this pair of 32-foot solar arrays would theoretically generate some five times the power that a spacecraft that size would normally pull in. Because spacecraft are almost without exception power-starved systems, having more watts to use or store for the orbital equivalent of a rainy day would certainly be welcome.

In another print, the robot arm could rearrange parts, snap on connectors and perform other tasks to create more complex structures like the ones in the concept art up top. That’s still well in the future, however — the current demonstrator mission will focus on the beam-and-array thing, though the team will certainly learn a lot about how to accomplish other builds in the process.

Naturally in-space manufacturing is a big concern for a country that plans to establish a permanent presence on and around the Moon. It’s a lot easier to make something there than make a quarter-million-mile delivery. You can keep up with Archinaut and Made In Space’s other projects along the space-printing line at the company’s blog.

These robo-ants can work together in swarms to navigate tricky terrain

Posted by | artificial intelligence, EPFL, Gadgets, hardware, robotics, science, TC | No Comments

While the agility of a Spot or Atlas robot is something to behold, there’s a special merit reserved for tiny, simple robots that work not as a versatile individual but as an adaptable group. These “tribots” are built on the model of ants, and like them can work together to overcome obstacles with teamwork.

Developed by EPFL and Osaka University, tribots are tiny, light and simple, moving more like inchworms than ants, but able to fling themselves up and forward if necessary. The bots themselves and the system they make up are modeled on trap-jaw ants, which alternate between crawling and jumping, and work (as do most other ants) in fluid roles like explorer, worker and leader. Each robot is not itself very intelligent, but they are controlled as a collective that deploys their abilities intelligently.

In this case a team of tribots might be expected to get from one end of a piece of complex terrain to another. An explorer could move ahead, sensing obstacles and relaying their locations and dimensions to the rest of the team. The leader can then assign worker units to head over to try to push the obstacles out of the way. If that doesn’t work, an explorer can try hopping over it — and if successful, it can relay its telemetry to the others so they can do the same thing.

fly tribot fly

Fly, tribot, fly!

It’s all done quite slowly at this point — you’ll notice that in the video, much of the action is happening at 16x speed. But rapidity isn’t the idea here; similar to Squishy Robotics’ creations, it’s more about adaptability and simplicity of deployment.

The little bots weigh only 10 grams each, and are easily mass-produced, as they’re basically PCBs with some mechanical bits and grip points attached — “a quasi-two-dimensional metamaterial sandwich,” according to the paper. If they only cost (say) a buck each, you could drop dozens or hundreds on a target area and over an hour or two they could characterize it, take measurements and look for radiation or heat hot spots, and so on.

If they moved a little faster, the same logic and a modified design could let a set of robots emerge in a kitchen or dining room to find and collect crumbs or scoot plates into place. (Ray Bradbury called them “electric mice” or something in “There will come soft rains,” one of my favorite stories of his. I’m always on the lookout for them.)

Swarm-based bots have the advantage of not failing catastrophically when something goes wrong — when a robot fails, the collective persists, and it can be replaced as easily as a part.

“Since they can be manufactured and deployed in large numbers, having some ‘casualties’ would not affect the success of the mission,” noted EPFL’s Jamie Paik, who co-designed the robots. “With their unique collective intelligence, our tiny robots can demonstrate better adaptability to unknown environments; therefore, for certain missions, they would outperform larger, more powerful robots.”

It raises the question, in fact, of whether the sub-robots themselves constitute a sort of uber-robot? (This is more of a philosophical question, raised first in the case of the Constructicons and Devastator. Transformers was ahead of its time in many ways.)

The robots are still in prototype form, but even as they are, constitute a major advance over other “collective” type robot systems. The team documents their advances in a paper published in the journal Nature.

Twitch continues to dominate live streaming with its second-biggest quarter to date

Posted by | esports, Facebook, facebook gaming, game streaming, Gaming, live streaming, Media, microsoft mixer, streamelements, streaming video, Twitch, YouTube, YouTube Live | No Comments

Twitch continues to lead rivals including, YouTube Live, Facebook Gaming and Microsoft’s Mixer, when it comes to live-streaming video. Despite experiencing its first decline in hours watched in Q2 2019, the Amazon-owned game-streaming site still had its second-biggest quarter to date, with more than 70% of the hours watched during the quarter.

According to a new report from StreamElements, Twitch viewers live-streamed a total of 2.72+ billion hours in Q2 — or 72.2% of all live hours watched — compared with 735.54 million hours on YouTube Live (19.5%), 197.76 million on Facebook Gaming (5.3%) and just 112.29 million hours (3%) on Mixer.

Page 4

Combined, the total hours watched across all four platforms was 3.77 billion in Q2.

While none of Twitch’s rivals are nearly catching up, YouTube Live did have a good month in May, breaking its own record with 284 million hours watched. Overall, YouTube Live’s hours watched improved in Q2 as a result, while Twitch saw a slight decline.

Facebook Gaming is also gaining steam. It’s now the third-biggest live-streaming platform, having passed Microsoft Mixer.

Page 3

Despite its traction, Twitch doesn’t have much of a long tail when it comes to stream viewership. That’s a problem it has faced for some time, as newcomers complained they spent years broadcasting to no one in hopes of gaining a fan base, with little success. Twitch has tried to remedy this problem with various educational efforts as well as product features like Raids and Squad Streams, for example.

However, the new report finds that the majority (almost 75%) of Twitch’s viewership still comes from people tuning in to the top 5,000 channels. Out of the 2.7 billion hours watched in Q2, these top 5,000 channels drove 2 billion of those hours watched.
