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
