T-RHex Is a Hexapod Robot With Microspines on Its Feet

Post Syndicated from Evan Ackerman original https://spectrum.ieee.org/automaton/robotics/robotics-hardware/trhex-hexapod-robot-microspines

Tiny spikes allow this robot to climb its way up steep slopes and grip onto rough surfaces

In Aaron Johnson’s “Robot Design & Experimentation” class at CMU, teams of students have a semester to design and build an experimental robotic system based on a theme. For spring 2019, that theme was “Bioinspired Robotics,” which is definitely one of our favorite kinds of robotics—animals can do all kinds of crazy things, and it’s always a lot of fun watching robots try to match them. They almost never succeed, of course, but even basic imitation can lead to robots with some unique capabilities.

One of the projects from this year’s course, from Team ScienceParrot, is a new version of RHex called T-RHex (pronounced T-Rex, like the dinosaur). T-RHex comes with a tail, but more importantly, it has tiny tapered toes, which help it grip onto rough surfaces like bricks, wood, and concrete. It’s able to climb its way up very steep slopes, and hang from them, relying on its toes to keep itself from falling off.

This Robot Ostrich Can Ride Around on Hovershoes

Post Syndicated from Evan Ackerman original https://spectrum.ieee.org/automaton/robotics/robotics-hardware/cassie-on-hovershoes

Cassie gets a speedy new pair of shoes. Wheee!

Proponents of legged robots say that they make sense because legs are often required to go where humans go. Proponents of wheeled robots say, “Yeah, that’s great but watch how fast and efficient my robot is, compared to yours.” Some robots try and take advantage of wheels and legs with hybrid designs like whegs or wheeled feet, but a simpler and more versatile solution is to do what humans do, and just take advantage of wheels when you need them.

We’ve seen a few experiments with this. The University of Michigan managed to convince Cassie to ride a Segway, with mostly positive (but occasionally quite negative) results. A Segway, and hoverboard-like systems, can provide wheeled mobility for legged robots over flat terrain, but they can’t handle things like stairs, which is kind of the whole point of having a robot with legs anyway.

At UC Berkeley’s Hybrid Robotics Lab, led by Koushil Sreenath, researchers have taken things a step further. They are teaching their Cassie bipedal robot (called Cassie Cal) to wheel around on a pair of hovershoes. Hovershoes are like hoverboards that have been chopped in half, resulting in a pair of motorized single-wheel skates. You balance on the skates, and control them by leaning forwards and backwards and left and right, which causes each skate to accelerate or decelerate in an attempt to keep itself upright. It’s not easy to get these things to work, even for a human, but by adding a sensor package to Cassie the UC Berkeley researchers have managed to get it to zip around campus fully autonomously.

VelociRoACH Gets New Shell for Robot-on-Robot Smashing

Post Syndicated from Evan Ackerman original https://spectrum.ieee.org/automaton/robotics/robotics-hardware/velociroach-gets-new-shell-for-robotonrobot-smashing

Repeated headbutting helps little legged robots flip each other over

UC Berkeley’s VelociRoACH robots are something like a decade old—the first one, DASH, was presented at IROS 2009, back when IROS was small enough to fit into a Hyatt in St. Louis, Mo. The upgraded VelociRoACH showed up next year, and we’re still seeing it being used for innovative new research. The great thing about these little robots is that they’re cheap, easy to build (mostly cardboard), and even easier to modify, so they’ve evolved rapidly over the years with things like wings and winches and drone launchers

A few years ago, the addition of a shell (which actual roaches have) plus a tail (which actual roaches thankfully do not have) allowed VelociRoACH to flip itself over if it ended up upside down. This worked really well, but it did add a little bit of complication and expense to the VelociRoACH design. Not complication or expense that you’d care about if you were just making one robot, or 10 robots, or even maybe a 100 robots, but the whole point of making super cheap little mobile robots like VelociRoACH is that you want to be able to churn out thousands of them, and then deploy them in ginormous swarms to (say) find people in rubble after an earthquake. 

The latest version of VelociRoACH leverages the swarm idea to solve the flipped-over robot problem using nothing more than a slightly-redesigned shell. Instead of using a cockroach-like rounded robot, a square-fronted shell allows one robot to simply smash itself headfirst into another robot until it flips it over. 

Video Friday: This Robot Is Learning to Slice Onions

The best robot videos from the world’s biggest robotics conference

We hope you’ve been enjoying our ICRA 2019 coverage, which has featured an upgraded Salto robot jumping outdoors, a new version of the HyQ quadruped pulling a plane, and a promising new approach to robot simulation and learning. We’ll have lots more from the conference over the next few weeks, but for you impatient types, we’re cramming Video Friday this week with a selection of ICRA videos.

As usual with our Video Friday ICRA editions, we tried to cover many different areas of robotics: control, humanoids, manipulators, aerial vehicles, AI, etc. We’re posting the abstracts along with the videos, but if you have any questions about these projects, let us know and we’ll get more details from the authors. And of course, this is just a small sample of an enormous amount of amazing research presented at ICRA—if you don’t see your favorite project here, please email us and we’ll try to write about it some time soon.

We’ll return to normal Video Friday next week. Have a great weekend everyone!

UC Berkeley’s “Hyper-Aggressive Pogo-Stick” Robot Now Works Outdoors

Post Syndicated from Evan Ackerman original https://spectrum.ieee.org/automaton/robotics/robotics-hardware/upgraded-salto-goes-for-a-bounce-outside-the-lab

Salto gets an upgrade and now it can go for a bounce outside the lab

UC Berkeley’s Salto has been one of our favorite robots since 2016, which makes it old-ish in robot years. While it’s kept the same “hyper-aggressive pogo-stick” concept, a series of upgrades has endowed Salto with with the ability to do increasingly more dynamic maneuvers.

The original Salto could make two jumps in a row. Thrusters added in 2017 gave the robot the control it needed to chain together multiple jumps. And late last year at IROS, an improved controller gave Salto the intelligence that it needed to make pinpoint jumps that allowed it traverse a series of vertical obstacles (and more).

The big constraint has always been that in order for Salto to keep itself upright and in one piece, it had to jump within a motion-capture environment, which limited its usefulness to (let’s be honest) not much more than a cool research project and highly effective YouTube video view generator.

Today at ICRA, UC Berkeley roboticists Justin Yim and Eric Wang (from Ron Fearing’s Biomimetic Millisystems Lab) presented the latest version of Salto, which adds the sensing and computing required to do away with the motion-capture system completely. Salto can now jump as much as you want out of the lab, and in fact completely outdoors.
