See Spot dance: Watch a Boston Dynamics robot get a little funky

Posted by | big dog, boston dynamics, Gadgets, robots, TC | No Comments

In this fun video the Boston Dynamics Spot dances, wiggles, and shimmies right into our hearts. This little four-legged robot – a smaller sibling to the massive Big Dog – is surprisingly agile and the team at Boston Robotics have taught the little robot to dance to Bruno Mars which means that robots could soon replace us on the factory floor and on the dance floor. Good luck, meatbags!

As one YouTube commenter noted: if you think Spot is happy now just imagine how it will dance when we’re all gone!

The Salto-1P now does amazing targeted jumps

Posted by | Gadgets, marc raibert, robots, TC | No Comments

When we last met with Salto the jumping robot it was bopping around like a crazed grasshopper. Now researchers have added targeting systems to the little creature, allowing it to maintain a constant hop while controlling exactly when and where Salto lands.

Called “deadbeat foot placement hopping control,” the Salto can now watch a surface for a target and essentially fly over to where it needs to land using built-in propellers.

Researchers Duncan Haldane, Justin Yim and Ronald Fearing created the Salto as part of the Army Research Office, and they will be exhibiting the little guy at the 2018 IEEE/RSJ International Conference on Intelligent Robots and Systems.

The team upgraded Salto’s controller to make it far more precise on landing, a feat that was almost impossible using the previous controller system, SLIP. “The robot behaves more or less like a spring-loaded inverted pendulum, a simplified dynamic model that shows up often enough in both biology and robotics that it has its own acronym: SLIP,” wrote Evan Ackerman at IEEE. “Way back in the 1980s, Marc Raibert developed a controller for SLIP-like robots, and people are still using it today, including Salto-1P up until just recently.”

Watch this tiny robot crawl through a wet stomach

Posted by | Gadgets, research, robots, TC | No Comments

While this video shows a tiny robot from the City University of Hong Kong doing what amounts to a mitzvah, we can all imagine a future in which this little fellow could stab you in the kishkes.

This wild little robot uses electromagnetic force to swim or flop back and forth to pull itself forward through harsh environments. Researchers can remotely control it from outside of the body.

“Most animals have a leg-length to leg-gap ratio of 2:1 to 1:1. So we decided to create our robot using 1:1 proportion,” said Dr. Shen Yajing of CityU’s Department of Biomedical Engineering.

The legs are .65 mm long and pointed, reducing friction. The robot is made of “silicon material called polydimethylsiloxane (PDMS) embedded with magnetic particles which enables it to be remotely controlled by applying electromagnetic force.” It can bend almost 90 degrees to climb over obstacles.

The researchers have sent the little fellow through multiple rough environments, including this wet model of a stomach. It also can carry medicines and drop them off as needed.

“The rugged surface and changing texture of different tissues inside the human body make transportation challenging. Our multi-legged robot shows an impressive performance in various terrains and hence open wide applications for drug delivery inside the body,” said Professor Wang Zuankai.

The team hopes to create a biodegradable robot in the future, which would allow the little fellow to climb down your esophagus and into your guts and then, when it has dropped its payload, dissolve into nothingness or come out your tuchus.

Watch this self-solving Rubik’s cube march its way across a table

Posted by | Gadgets, puzzles, robots, TC, toys | No Comments

This wild, 3D-printed self-solving Rubik’s cube is amazing. To make it work, a Japanese inventor used servo motors and Arduino boards to actuate the cube as it solves itself. Sadly, there isn’t much of a build description available but it looks to be very compact and surprisingly fast.

There is a description of the project on DMM-Make and you can watch the little cube scoot around a table as it solves itself in less than a minute. The creator also built the Human Controller, a cute system for controlling a human as they walk down the street, and the Human Crane Game which is equally inexplicable. If this Ru-bot is real and ready for prime time it could be an amazing Kickstarter.

Researchers train bipedal robots to step lightly over rough terrain

Posted by | berkley, cmu, Gadgets, robots, TC | No Comments

Researchers at the Hybrid Robotics Group at UC Berkeley and CMU are hard at work making sure their robots don’t fall over when tiptoeing through rough terrain. Using machine learning and ATRIAS robots, the teams are able to “teach” robots to traverse stepping stones they’ve never seen before.

Their robots, described here, are unique in that they are bipedal and use a mixture of balance and jumping to ensure they don’t tip off the blocks.

“What’s different about our methods is that they allow for dynamic walking as opposed to the slower quasi-static motions that robots tend to use,” write the researchers. “By reasoning about the nonlinearities in the dynamics of the system and by taking advantage of recent advances in optimal and nonlinear control technology, we can specify control objectives and desired robot behaviors in a simple and compact form while providing formal stability and safety guarantees. This means our robots can walk over discrete terrain without slipping or falling over, backed by some neat math and some cool experimental videos.”

The robots are currently “blind” and can’t use visual input to plan their next move. However, with a robot called CASSIE, they will be able to see and feel the stones as they hop along, ensuring that they don’t tip over in the heat of fun… or battle.

This robotic hose-dragon could jet its way into burning buildings

Posted by | Asia, Dragons!, Gadgets, hardware, robotics, robots, TC | No Comments

While hose-toting drones may be a fantasy, hose-powered robo-dragons (or robotic hose-dragons — however you like it) are very much a reality. This strange but potentially useful robot from Japanese researchers could snake into the windows of burning buildings, blasting everything around it with the powerful jets of water it uses to maneuver itself.

Yes, it’s a real thing: Created by Tohoku University and Hachinohe College, the DragonFireFighter was presented last month at the International Conference on Robotics and Automation.

It works on the same principle your hose does when you turn it on and it starts flapping around everywhere. Essentially your hose is acting as a simple jet: the force of the water being blasted out pushes the hose itself in the opposite direction. So what if the hose had several nozzles, pointing in several directions, that could be opened and closed independently?

Well, you’d have a robotic hose-dragon. And we do.

The DragonFireFighter has a nozzle-covered sort of “head” and what can only be called a “neck.” The water pressure from the hose is diverted into numerous outlets on both in order to create a stable position that can be adjusted more or less at will.

It requires a bit of human intervention to go forwards, but, as you can see, several jets are pushing it that direction already, presumably at this point for stability and rigidity purposes. If the operators had a little more line to give it, it seems to me it could zoom out quite a bit farther than where it was permitted to in the video.

For now it may be more effective to just direct all that water pressure into the window, but one can certainly imagine situations where something like this would be useful.

DragonFireFighter was also displayed at the International Fire and Disaster Prevention Exhibition in Tokyo.

One last thing. I really have to give credit where credit’s due: I couldn’t possibly outdo IEEE Spectrum’s headline, “Firefighting Robot Snake Flies on Jets of Water.”

These robotic skiers hit the slopes in style

Posted by | Gadgets, robots, TC | No Comments

 Researchers took part in the Ski Robot Challenge last month and the resulting videos – essentially quick cuts of robots in ski jackets totally whanging off the gates and spinning out in the powder. The Challenge, run by the Korea Institute for Robot Industry Advancement, is sort of a Winter Olympics for wonky androids. The rules are pretty complex. According to Spectrum: Each robot must… Read More
