Unitree Dex3-1 Review Summary
The Dex3-1 is the simple hand in Unitree's range. A thumb with three joints and two fingers with two joints each are enough to pinch, wrap and hold most objects, with seven motors instead of the sixteen of a five-finger hand. Every joint is force-controlled, and 33 tactile sensors cover the palm, pads and tips. It weighs 710 g. The limit is load: 500 g. This is a hand for learning manipulation, not for lifting.

Force control on all joints
33 tactile sensors
Light at 710 g
