This robot hand can detach from its arm and crawl around

Breakthroughs, discoveries, and DIY tips sent six days a week. Engineers in Switzerland recently created a detachable, spider-like robot hand capable of grabbing multiple objects and using its fingers to crawl. The unsettling device, reminiscent of a threatening video game creature, can separate itself from a mounted robot arm, tip-toe (or really, tip-) its way toward small objects, pick them up, and carry them on its back. The symmetrical design and flexible fingers mean that the robot can transport objects on either side of its body. For humans, that would look like holding a ball in your palm while simultaneously grasping a piece of fruit on the back of your hand.
