Overview

The RH56H1 — taglined Ultra Compact, Ultimate Power — is Inspire Robots' most compact dexterous hand and the most densely instrumented platform in the lineup. At 159.70 × 75.18mm and 470g, it is the smallest and lightest hand Inspire Robots produces, yet it delivers flagship-tier performance: 15N thumb fingertip strength, 8 kg passive payload per finger, and 1 kHz real-time communication.

Where the H1 stands apart from every other RH56 model is tactile coverage. 170 fingertip tactile sensors (34 per finger) and 90 palm tactile sensors give it 260 total sensing points — the richest haptic awareness in the Inspire Robots lineup by a wide margin. Its all-metal structure provides exceptional rigidity, and advanced software algorithms support multiple simultaneous intelligent control modes. Available in two interface configurations: RS485+CAN FD or EtherCAT+RS485+CAN FD.

Key Features
  • 159.70 × 75.18mm form factor — smallest and most compact hand in the Inspire Robots lineup
  • 470g — lightest dexterous hand in the RH56 family; minimal impact on robot arm payload budget
  • 170 fingertip tactile sensors — 34 per finger; highest per-finger tactile density in the lineup
  • 90 palm tactile sensors — full palm surface coverage for localized contact detection
  • 260 total tactile sensing points — richest haptic awareness of any Inspire Robots hand
  • 1 kHz real-time communication — millisecond-level response across all 6 DOF
  • ≥15N thumb / ≥10N finger grip force — flagship-tier grip in a compact body
  • 8 kg passive payload per finger — robust and stable heavy-duty grasping capability
  • All-metal structure — exceptional rigidity matching larger, heavier hands in the lineup
  • Multiple intelligent control modes — force, position, and impedance control running simultaneously
  • Triple protocol support — RS485, CAN FD, and EtherCAT (E6 variants) on a single unit
  • Left and right hand configurations — available as matched pairs for bimanual setups

Use Cases
  • Space-constrained humanoid integration — 470g and 160mm height fits platforms where larger hands cannot mount
  • High-fidelity tactile sensing research — 260 sensing points enable texture recognition, slip detection, and contact localization at a resolution no other RH56 model matches
  • Embodied AI and robot learning — dense fingertip and palm tactile data for training dexterous manipulation and in-hand manipulation policies
  • NVIDIA Isaac Lab / Isaac Sim pipelines — compact form factor with 1 kHz EtherCAT for sim-to-real transfer on smaller humanoid platforms
  • Prosthetics research — lightweight and compact with human-comparable grip force; suited for wearable and assistive device programs
  • VR teleoperation with haptic feedback — rich tactile data stream enables detailed closed-loop operator feedback
  • Bimanual dexterous manipulation — matched left/right pairs for two-handed tasks on compact humanoid platforms
