A Five-Fingered Marvel: ETH Zurich Robotic Hand in Motion
In a groundbreaking development, researchers at ETH Zurich’s Soft Robotics Lab have engineered a five-fingered robotic hand that autonomously walks on its fingertips, much like a character from The Addams Family. This advanced creation represents an innovative design that transforms the hand itself into a mobile robot, using its fingers for both locomotion and interaction with surroundings.
Reinforcement Learning: Mastering Finger-Based Locomotion with the ETH Zurich Robotic Hand
The device’s movement is a marvel of reinforcement learning, allowing it to navigate diverse terrains. Unlike conventional designs with wheels or legs, this hand relies on its own fingers, each equipped with four actuated joints, to balance and move. The researchers trained it in simulation to walk and interact seamlessly with different environments.
It successfully moved across 14 varied surfaces such as tile and gravel. Remarkably, it demonstrated an ability to right itself from a fallen position in 21 out of 25 tests. The hand even performed precise tasks like pressing keyboard keys, achieving 29 out of 32 targets accurately.

Exploring Dual Capabilities: Mobility Meets Manipulation
Beyond walking, this robotic hand showcases an ability to manipulate objects while maintaining balance. In experiments, it pushed small objects toward targets, proving its dual function as both a mover and a manipulator. This shift from traditional robotic designs could streamline robotic systems, eliminating the need for separate mobile platforms.
Envisioned as a versatile tool, this innovation could reach confined spaces independently, perform tasks, and return for retrieval, offering a new paradigm in robotic mobility and functionality powered by artificial intelligence.
Advanced Mobility: A Step Towards the Future
With 20 actuated joints and compact design, the robotic hand weighs only 818 grams yet navigates both indoor and outdoor environments. Future enhancements aim to improve onboard perception and movement versatility, further redefining robotics. This cutting-edge project at ETH Zurich charts an intriguing course for autonomous systems.
