Overview

The RH56E2 is Inspire Robots' heavy-load dexterous hand — delivering 30N thumb grip force and 28N per-finger force alongside an integrated tactile sensor array for contact-aware manipulation. Built on a hybrid force-position-tactile control algorithm, it mimics human hand gripping capability and provides real-time localized feedback across the palm surface.

The RH56E2 is available in two tactile configurations: T1 Resistive (17 sensors, 0–30N range) for high-force contact detection, and T2 Capacitive (5 sensors, 0–20N range) for finer sensitivity at lower force levels. Both configurations support RS485, CAN, and ModbusTCP on a single unit. Power-off self-locking holds the grip without continuous power. Directly compatible with the Unitree G1 and H2 humanoid robot platforms.

Key Features
  • 30N thumb / 28N per-finger grip force — strongest grip in the accessible RH56 lineup; comparable to human hand grasping force
  • Integrated tactile sensor array — T1 Resistive: 17 sensors, 0–30N range / T2 Capacitive: 5 sensors, 0–20N range
  • Force resolution 0.05N — 10× finer than the RH56BFX/DFX; enables precise grip force modulation
  • Hybrid force-position-tactile control — three sensing modalities working simultaneously for stable, adaptive grasping
  • Triple protocol support — RS485, CAN, and ModbusTCP on a single unit; no additional adapters required
  • ≥5 independent force sensors — real-time per-finger force distribution feedback
  • Power-off self-locking — holds grip position without power; no repositioning required on startup
  • ±0.20mm repeatability — sub-millimeter precision across all 6 DOF
  • Unitree G1 / H2 compatible — direct integration with Unitree humanoid robot platforms
  • ROS / ROS 2 compatible — plugins available for direct integration
  • Left and right hand configurations — available as matched pairs for bimanual setups

Use Cases
  • Humanoid robot hand integration — direct replacement or upgrade for Unitree G1 and H2 platforms
  • Contact-rich manipulation — tasks requiring real-time tactile awareness: assembly, sorting, object classification by feel
  • Prosthetics research and development — human-comparable grip force with tactile sensing for assistive device programs
  • Cognitive robotics research — localized tactile data enables object recognition and texture differentiation through touch
  • Fragile object handling — tactile feedback prevents overgrip on delicate items; force thresholds adjustable per task
  • Embodied AI training datasets — high-fidelity force and tactile data for dexterous manipulation model development
  • VR teleoperation with haptic feedback — force and tactile data streams for closed-loop operator feedback systems
  • Unmanned laboratory automation — handling pipettes, vials, and varied lab consumables with tactile awareness
