The U21T is the touch-sensing version of BrainCo's Revo 3 hand, offered here for the Unitree H2 EDU PLUS humanoid together with an SHF3L sensing camera. What it adds over the plain U21 is a full-palm tactile array.
That array measures from 0 to 25 N at 0.01 N resolution and registers pressure, contact events and incipient slip across the palm. A controller can therefore confirm a grasp by touch and adjust its force instead of assuming the object is secure.
It suits grasp-stability studies, slip-aware controllers and touch-conditioned learning, as well as development of contact-rich tasks such as insertion, fastening and part seating. Compared with the U21V it leaves out fingertip vision, which also leaves out the calibration and compute that vision brings.
Under the sensors it keeps the Revo 3 mechanics: 21 degrees of freedom on direct-drive, backdrivable joints, over 70 N of grasp force and over 20 N of fingertip pinch. Handedness, quantity, hand weight, the number of cameras and the mounting for your H2 unit are confirmed on your quotation.
Key Capabilities
-
Full-palm tactile array: A tactile array covers the whole palm and maps contact and pressure distribution.
-
0.01 N resolution: The array measures from 0 to 25 N and registers pressure, contact events and incipient slip.
-
Grasps checked by touch: Palm data lets a controller confirm a grip and adjust force instead of assuming the object is secure.
-
21 direct-drive joints: Four fingers with 4 degrees of freedom each and a 5-DoF thumb run on backdrivable joints.
-
Over 70 N grasp, over 20 N pinch: The hand closes at 3 Hz under a 500 Hz control rate, with a 20 kg overall payload.
-
SHF3L sensing camera included: The camera adds 1920 × 1536 video at 30 fps across a 196° horizontal field of view.
-
Touch without fingertip vision: Tactile-only sensing avoids the extra calibration and compute that the U21V's fingertip vision brings.
Buying through Robotix Market
