- Modular user-replaceable fingers Each finger is a self-contained unit that the user can replace independently for fast repair and high experimental uptime during long-running RL experiments.
- 12 DoF tendon-driven actuation Twelve degrees of freedom across three fingers, driven by tendons in an N+1 motor configuration per finger for redundancy and improved reliability.
- 10 kHz force control loops High-frequency control within motor units enables active compliance; higher-level position control runs at 1 kHz on a host computer.
- 155 sensor channels per finger Rich proprioceptive sensing per finger covering joint position, force, and inertial measurements at high update rates.
- Camera-based distal tactile sensing Optical fingertip sensors deliver video at 1280×480 resolution and 50 FPS over a single USB 3.0 connection, with hundreds of tactile taxels per finger.
- DEX-EE Chiral variant A chiral configuration offsets the third finger to approximate a human thumb, simplifying teleoperation and bi-manual manipulation strategies; available in left, right, and paired configurations.
Descrizione
The Shadow DEX-EE is a three-fingered dexterous hand engineered specifically for the demands of reinforcement learning and imitation learning research, where hardware is routinely subjected to repeated impacts, high contact forces, and unpredictable behaviors from untrained policies. Each finger is a self-contained, user-replaceable module—allowing a damaged finger to be swapped out while repairs are completed separately, minimizing downtime in long-running experiments. At approximately 350 mm in height and 4.1 kg for the three-finger configuration, the DEX-EE is larger than a human hand and built for endurance rather than compactness.
The hand delivers 12 degrees of freedom across its three fingers, with tendon-driven actuation using an N+1 motor configuration per finger for added reliability. Control loops operate at up to 10 kHz for force control within motor units and 1 kHz for higher-level position control on a host computer. Each finger carries 155 individual sensor channels covering position, force, and inertial measurements, plus a camera-based distal tactile sensor outputting video at 1280×480 resolution and 50 FPS over a single USB 3.0 connection. A DEX-EE Chiral variant repositions the third finger to resemble a human thumb offset, supporting teleoperation and bi-manual task workflows.

Settori industriali
Domande frequenti
The DEX-EE is a dexterous robotic hand designed for reinforcement learning and imitation learning research, particularly in environments where hardware must endure repeated impacts, high contact forces, and unpredictable behaviors generated by untrained policies.
It provides 12 degrees of freedom across three tendon-driven fingers with N+1 motor redundancy, 10 kHz force control loops, 155 sensor channels per finger, and camera-based optical tactile sensing at 1280×480 resolution and 50 FPS. User-replaceable finger modules enable fast repair without full disassembly.
It is primarily suited to academic and industrial research laboratories focused on dexterous manipulation, machine learning for robotics, tactile sensing, and teleoperation research. The DEX-EE Chiral variant is additionally suited to bi-manual manipulation and teleoperation workflows.
