This image provided by Ryan Truby, Michael Wehner, and Lori Sanders, Harvard University, shows the octobot, an entirely soft, autonomous robot. A pneumatic network, red, is embedded within the octobot’s body and hyperelastic actuator arms, blue. The latest revolutionary robot isn’t the hardened costly machine you’d expect: It’s squishy like Silly Putty, wireless, without a battery and is made for pennies by a 3-D printer. Meet Octobot. It looks like a tiny octopus, designed to be mimic that slithery creature to get through cracks and tight places, making it ideal as a rescue robot.
