R1 is a high-precision haptic glove designed specifically for teleoperating dexterous humanoid robot hands. With a total of 40 tracked finger degrees of freedom, integrated grasp force sensing, active force feedback on the fingers, and vibrotactile feedback in the fingertips and palm, the glove enables intuitive and reliable control. It supports both direct teleoperation and imitation learning, making it a powerful interface for advanced teleoperation and robotics systems.
Applications
- Teleoperation of robotic hands
- Imitation learning including force data
- Research in dexterous manipulation
Key Features
- Active Force Feedback (AFFB)
- Thumb, index, middle, and ring fingers are equipped with AFFB modules that provide targeted resistance on the operator’s fingers, simulating rigid objects in the robot’s grasp or the restorative pull of elastic materials. The feedback is strong enough to simulate firm grip resistance.
Vibration Feedback
Vibrotactile actuators are integrated in all fingertips (5) and the palm (3) to allow the operator to feel surface textures such as rough or smooth. They can also convey tactile cues such as button clicks, tool vibrations, light touches, or UI signals.
Precision Finger Tracking
40 rotary Hall-effect sensors (5 fingers × 8 joints) provide robust, millimeter-precision tracking of all fingers at the fingertips and along each phalanx.
Force Sensing
Each AFFB module includes a force sensor, enabling operation and imitation learning with both precise finger motion and grasp force data. Combined with robot hands featuring force sensing or current measurement, it allows highly realistic and stable grasp simulations.
