About this product

XHAND 1 is Robotera's five-finger hand designed for AI research and robotic manipulation. Its 12 active degrees of freedom are distributed as three each in the thumb and index finger and two in each remaining finger. Motors and gears provide independent joint control, including index-finger lateral movement. Optional high-resolution tactile sensors provide three-dimensional contact-force and temperature information. The official brochure lists a 1.1 kg mass, Linux SDK and ROS-compatible applications, together with glove and visual-mapping teleoperation support for testing and training-data collection.
