For LEAP Hand

by Carnegie Mellon University

1,472 measurements with minimal wiring in an open-source hand.

The LEAP Hand, developed by Carnegie Mellon University, is a dexterous and anthropomorphic robotic hand built for high-performance manipulation tasks. Its novel kinematic structure maintains consistent dexterity across a wide range of finger poses, making it suitable for complex handling applications.

XELA Robotics has equipped the LEAP Hand with 368 integrated sensing points, providing high-resolution contact feedback across the entire hand surface. This enables precise control, improved adaptability, and enhanced reliability in demanding environments. The curved fingertip design enables more natural object interaction, and its outer layer can be replaced for long-term reliability. The microcontrollers are encapsulated and are mounted to the back of the fingers and the inside of the palm. Users can choose which part of the hand to cover with sensors. Only one cable with four wires is required for the sensors in each finger, and two cables for the whole hand (two CAN bus cables). The cabling of the LEAP hand actuation has also been improved to remove dangling wires.

When ordering a LEAP hand with uSkin sensors, XELA Robotics provides the robot hand itself at the cost of the parts.
