MIT researchers built a 70-pound robot "cheetah" meant to demonstrate the high efficiency of a new electric motor design. Among other improvements, the design enables the impact energy of the robot's leg hitting the ground to be captured and fed into the robot's battery. Soon, they expect the motors to enable the cheetah-bot to gallop at 35 mph which, of course, is still just half the speed of a real cheetah. However, it will hit those speeds much more efficiently than other running robots.
Sangbae Kim, the Esther and Harold E. Edgerton Assistant Professor in MIT’s Department of Mechanical Engineering, says achieving energy-efficiency in legged robots has proven extremely difficult. Robots such as Boston Dynamic’s “Big Dog” carry heavy gasoline engines and hydraulic transmissions, while other electrically powered robots require large battery packs, gears, force sensors and springs to coordinate the joints in a robot’s leg. All this weighty machinery can add up to significant wasted energy, particularly when a robot’s legs need to make frequent contact with the ground in order to trot or gallop.
On Saturday, Franky Zapata took his prototype Flyboard Air hoverboard for a rather impressive flight, three miles on the French coast. It’s based on Zapata’s previous water-powered hoverboard. When the first short flight video went up last month, The Verge interviewed Zapata: So there’s three parts to this, right? The board, a fuel tank, and […]
Media artist Michael Naimark writes: In 1990, right as the first VR wave was swelling, Stewart Brand and Grateful Dead manager Jon Mcintyre concocted a scheme to produce an invitation-only 24-hour VR event modeled after the Electric Cool-Aid Acid test. They convinced Colossal Pictures, the largest soundstage in San Francisco, to host it. Dozens of […]
Almost everyone has their smartphone in a case of one kind or another. Beyond simple protection, finding a case that can charge your phone on its own, but doesn’t feel like it’s also adding a couple pounds to the phone’s weight is the tricky part. Billed as the world’s thinnest battery case, the ThinCharge iPhone […]
You never know when new projects, ideas or opportunities can drop into your lap at a moment’s notice. That may require you to learn a new programming language like Python. Or maybe you need a primer on 3D game development. Or you might realize you could use a serious brush-up on iOS mobile creation.Point is, […]
Isn’t it about time to stretch what your Mac can do? I mean, you’ve got plenty of great programs now…but don’t you think you could use some new tools to get your creative, analytical and organizational juices really flowing? It’s spring, so we cleaned up a whole bunch of super-cool apps lying around and packaged […]
