Colorado researchers build flexible robots that can join together

Colorado State University researchers have developed flexible modular robot prototypes that can bend, grip and connect with one another, the university said in a November 11 release.

The tube-like machines use a structure called tensegrity: rigid rods are supported by tensioned cables rather than locked into a fixed frame, according to the university. Their bodies have no traditional joints, and gripping claws at each end can hold objects or attach to other robots.

Researcher Jianguo Zhao said the units can work individually or combine into larger shapes. His colleague Mahmud Hasan Saikot said the systems currently need human pilots, though the team has demonstrated two robots finding and connecting to each other on their own. The team hopes to increase their speed and improve cooperation with less human supervision.

In an independent engineering account, Universe Today’s Andy Tomaswick discusses how flexible, modular robots might help navigate rough planetary terrain. He also identifies their current manual Wi-Fi control as a practical obstacle to use on deep-space missions.
