- 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.
Description
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.

Frequently Asked Questions
The Unitree H2 EDU PLUS BrainCo Revo 3 U21T Tactile Hand + SHF3L is priced at 193.990 kr in your market.
Its full-palm array measures from 0 to 25 N at 0.01 N resolution and registers pressure, contact events and incipient slip, so a grasp can be checked by touch while force is adjusted.
All three share the 21-joint Revo 3 mechanics. The U21 has no tactile sensors, the U21T has the palm array, and the U21V adds visuo-tactile sensing in the fingertips to that palm array.
The SHF3L sensing camera adds vision to the hand's touch data: 1920 × 1536 at 30 fps across a 196° horizontal field of view, under 50 g. The number of cameras and the mounting are confirmed on your quotation.
It communicates over EtherCAT, CAN FD or RS-485 at 500 Hz and runs on a 12–80 V supply, drawing up to 10 A at 24 V.
Handedness and quantity are confirmed on your quotation. The H2 robot is not included, and fit to your H2 EDU PLUS is confirmed at the same time.
