The cool factor about balloon animals is that, utilizing the identical fundamental inflatable constructing blocks, a talented particular person can create absolutely anything you would ask for. That very same methodology is what’s on the coronary heart of a latest Stanford College and College of California, Santa Barbara, comfortable robotics undertaking. Described by its creators as a “large-scale isoperimetric comfortable robotic,” it’s a human-scale robotic created from a collection of an identical robotic curler modules which might be mounted onto inflatable cloth tubes. Identical to the balloon animals you keep in mind, this results in some spectacular shape-shifting inventiveness.

“Whenever you make a balloon animal, you begin with a protracted straight tube and add joints in it by twisting the balloon,” Zack Michael Hammond, a researcher on the undertaking, informed Digital Traits. “You may then fold up the balloon at these joints to type shapes like a canine or a hat. That’s precisely how this robotic works. A collective of straightforward robots creates plenty of pinch factors within the tube permitting the tube to fold right into a 3D construction. These robots can then drive alongside the tube to maneuver these pinch factors, which causes the form of the construction to vary.”


The robotic has a truss construction, which means that it’s assembled with beams, often in triangular items, just like the Eiffel Tower. That is what offers it its capability to vary form the place required. By connecting the sub-unit robots collectively in numerous methods, or by including extra ones, the researchers can create quite a lot of buildings with totally different topologies, every suited to a selected job.

As a result of it’s a comfortable robotic, it’s inherently extra human-safe, in addition to being extra tolerant to touring on unsure terrain. In contrast to many comfortable robots, it will probably work with out bodily connection to an exterior supply of vitality. This can be a troublesome and essential hurdle for a lot of comfortable robotic applied sciences.

“One potential utility that we’re enthusiastic about is utilizing this sort of robotic for house exploration,” Nathan Scot Usevitch, one other researcher on the undertaking, informed Digital Traits. “Many of the robotic construction is simply inflated cloth tubing, so it may deflate and pack into a really small quantity for transport. As soon as it arrived on one other planet or moon it may inflate, after which start exploring with out a tether. It may use its giant shape-changing capability to journey over various terrain, getting lengthy and thin to squeeze by way of gaps, or stretching out to brace towards the partitions because it climbs.”

A paper describing the robotic was lately printed within the journal Science Robotics.
