ETH Zurich develops autonomous walking robotic hand

Researchers at ETH Zurich have developed an autonomous robotic hand capable of independent locomotion by using its fingers as legs. This innovation allows the device to navigate various terrains, including grass, wood, tiles, gravel, and stone, by coordinating five asymmetrical digital joints.

The device is self-contained, featuring an internal microcomputer, sensors, and a battery that manage autonomous mobility, stability, and fall control without the need for external cables. In practical tests, the hand has demonstrated the ability to balance on some fingers while using others to interact with a computer, such as pressing arrow keys in a puzzle game.

This technology is intended for inspection in confined spaces and search and rescue missions. Its ability to traverse irregular surfaces like rubble makes it a potential tool for exploring disaster zones and manipulating small objects or switches in areas inaccessible to traditional rescue equipment.
