Spherical Robot Rolls then Walks into Action
Intended as a proof of concept of a hybrid rolling-walking locomotion system, the QRoSS robot from Japan’s Chiba Institute of Technology is capable of some pretty amazing things already. Surrounded by a wire roll cage that’s independent of the robot’s legs, QRoSS is able to roll into position, unfurl its legs, and walk where it needs to go. Four independent legs make it sure-footed over rough terrain, with obvious applications in such fields as urban search and rescue; a hardened version could be tossed into a collapsed building or other dangerous environment and walk around to provide intelligence or render aid. The robot’s self-righting feature would be especially handy for that use case, and as you can see in the video below, it has a powered rolling mode that’s six times faster than its walking speed.
