Core Technologies & Specifications

Our comprehensive approach to achieving human-like dexterity in robotic systems

01 Structure & Kinematics

A tendon-driven, biomimetic structure at human scale — five fingers and an articulated 2-DoF wrist combine for 22 DoF (18 actuated) that reproduce natural hand motion.

• 0122 total DoF, with 18 actuated degrees of freedom
• 02Tendon-driven fingers — 4 joints each (abduction + MCP / PIP / DIP)
• 03Per-joint finger flexion to ~90°, with slight hyperextension
• 04Opposable thumb with ~120° of rotation
• 052-DoF wrist — flexion/extension (−30°…+65°) and ±30° deviation

02 Control System

On-board control for real-time, stable motion — hybrid position control with velocity and current saturation, solved directly on the hand.

• 0110 ms real-time response
• 0250 Hz hybrid position control (velocity + current saturation)
• 03On-board 50 Hz joint-position solver
• 04Automatic per-finger calibration routine

03 Proprioceptive Sensing

Every actuator reports its full state continuously, fused with a forearm IMU for accurate, drift-corrected pose estimation.

• 01Per-actuator voltage / position / velocity / current / temperature @ 50 Hz
• 02Forearm IMU with quaternion pose @ 100 Hz
• 03Closed-loop kHz PID at the actuator level
• 04On-board current and power sampling @ 10Hz

04 Tactile & Teleoperation Glove

A wearable glove for intuitive, high-fidelity teleoperation and data collection, with dense tactile sensing across the fingertips and palm.

• 01Glove IMU with quaternion pose @ 500 Hz
• 02Tactile sensing: 11.7 mN/ADC resolution, 0.1–125 N range
• 03Low-latency taxel sensing @ 500 Hz
• 04Total 96 Taxels on palm-side fingers and palm

05 Vision & Perception

An integrated wrist camera with a wide fish-eye field of view and a global shutter for crisp, motion-free capture during manipulation.

• 01160° diagonal fish-eye FOV (changeable lens)
• 02Global-shutter sensor, 60 FPS (1600×1200) / 90 FPS (1280x720)
• 03Manual Exposure / Auto Exposure / anti-flicker
• 04Driverless USB 2.0 — Linux out of the box

06 Connectivity & Compute

Plug-and-play integration — one driverless USB connection and an open, memory-safe software stack to bring the hand into any system.

• 01Single USB 2.0 hub — hand · glove · camera (+1 device on request)
• 02On-board real-time compute
• 03ZMQ + Cap’n Proto IPC driver (Realtime IPC / Remote over TCP)
• 04Python & C++ Client SDKs
• 05Memory-safe Rust — FW · driver · GUI
