Stanford makes giant soft robot from inflatable tubes


As much as we love soft robots (and we really love soft robots), the vast majority of them operate pneumatically (or hydraulically) at larger scales, especially when they need to exert significant amounts of force. This causes complications, because pneumatics and hydraulics generally require a pump somewhere to move fluid around, so you often see soft robots tethered to external and decidedly non-soft power sources. There’s nothing wrong with this, really, because there are plenty of challenges that you can still tackle that way, and there are some up-and-coming technologies that might result in soft pumps or gas generators.

Researchers at Stanford have developed a new kind of (mostly) soft robot based around a series of compliant, air-filled tubes. It’s human scale, moves around, doesn’t require a pump or tether, is more or less as safe as large robots get, and even manages to play a little bit of basketball.
