About this product

Dex3-1 is Unitree's three-finger dexterous hand for force-and-position-controlled manipulation and data collection with the G1 humanoid. Seven degrees of freedom are driven by six direct-drive joints and one geared joint. The official specification lists 33 pressure-sensing points, a 710 g mass and USB 2.0 communication at a stated 1 kHz rate. Joint position, velocity, torque and tactile feedback support application development. The manufacturer supplies open-source resources and a user manual, while its load and repeatability figures apply to the documented testing conditions.
