This Disembodied Hand Is All the Robot You Need
Researchers from ETH Zurich have developed a self-contained robotic hand that can walk on its fingertips and manipulate objects, using reinforcement learning and off-the-shelf hardware. The hand can navigate different surfaces, right itself, and push objects autonomously, suggesting new possibilities for modular and autonomous robotic systems.

witch between them as necessary. In real-world tests, the hand crawled across 14 different surfaces including smooth floors, metal grates, grass, and gravel. Other experiments confirmed that it could make both right and left turns, and hit an average speed of 9 centimeters per second. The hand was able to right itself in 21 of 25 trials. When given a video feed from an overhead camera, it even managed to autonomously

push a 41-gram cube to targets up to 40 cm away 15 times in a row. “What interests me most about this work is that the same fingers can move the hand, support its weight, and interact with its surroundings,” says Masahiko Inami , a professor at The University of Tokyo whose group has developed hand-shaped walking robots . He agrees that a mobile hand could be useful for reaching confined spaces and operating control

All four models fit on the onboard computer, says Kazemipour, and the controller can s
