Salto is a single-legged, hopping robot that its UC Berkeley inventors compare to a "hyper-aggressive pogo-stick." Previously, Salto was constrained to a highly-structured indoor environment with a motion caption system. Now though, roboticists Justin Yim and Eric Wang have imbued Salto with the onboard smarts to bounce freely through the world albeit still under human control. From UC Berkeley:
Salto’s single, powerful leg is modeled after those of the galago, or Senegalese bush baby. The small, tree-dwelling primate’s muscles and tendons store energy in a way that gives the spry creature the ability to string together multiple jumps in a matter of seconds. By linking a series of quick jumps, Salto also can navigate complex terrain — like a pile of debris — that might be impossible to cross without jumping or flying.
“Unlike a grasshopper or cricket that winds up and gives one jump, we’re looking at a mechanism where it can jump, jump, jump, jump,” (UC Berkeley robotics professor Ronald) Fearing said. “This allows our robot to jump from location to location, which then gives it the ability to temporarily land on surfaces that we might not be able to perch on.”
From IEEE Spectrum:
...The researchers expect that “higher precision estimation and control can enable jumping on more finely varied surfaces like stairs, furniture, or other outcroppings” as well as “soft substrates like upholstery or natural foliage.”
The researchers tell us that Salto’s hardware is capable enough at this point that aside from potentially upgrading the motor or battery for more jumping power or run time, the focus now will be on new behaviors, although they’re toying with the idea of adding some kind of gripping foot so that Salto can launch from, and land on, tree branches (!).
The fine folks at Boston Dynamics, busy building our future robotic overlords, have loaned Adam Savage a Spot robot for the Tested team to play with. For his first project, Adam built a gorgeous steampunk/Victorian rickshaw for Spot to pull. The results are glorious.
Robotic employees such as hotel concierges and English teachers are nothing new in Japan, but here is its first robotic bartender. QBIT Robotics created this chatty robot that works in one of Tokyo’s Yoronotaki izakaya restaurants.
Who cares about the Tokyo Olympics, when a 60-foot walking RX-78-2 robot is going to be stomping around nearby Yokohama in October? It will have 24 degrees of motion and will weigh 25 tons, according to New Atlas. It sounds pretty impressive, and the video above makes it seem cool, but Yoshiyuki Tomino, who created […]
Whether you’re managing a political campaign or building a client base, there comes a time when you stop seeing people and start seeing numbers. This doesn’t happen suddenly. You shake hands, make calls, and build relationships. And then those relationships disappear into a database of donors or customers as your organization grows. People get brought […]
Learning to ride a bike is one of those quintessential childhood experiences that’s as rewarding as it is scary. Prep your precious babe for success by starting them early with the world’s lightest balance bike, the Brilrider FLIGHT. For the uninitiated, balance bikes are no-pedal bicycles that propel forward by pushing off the ground with […]
With so many advancements in modern society, you’d think we’d have moved beyond the butane lighter by now. A pressurized, flammable gas, butane fumes can irritate your eyes and skin, can elevate your heart rate, and even lead to cardiac arrest. And we did mention that whole highly pressurized and flammable part, right? While certainly […]
