Overview

The RH56DFX is the balanced workhorse of the Inspire Robots RH56 lineup — combining 15N thumb grip force and 10N per-finger force with a 260°/s flexion speed capable of handling real grasping workloads. Where the BFX prioritizes speed, the DFX prioritizes force: delivering 2.5× the grip strength with integrated absolute position sensors and force sensors providing real-time feedback throughout every motion.

Six integrated micro linear servo actuators drive six degrees of freedom across 12 joints. Configurable force thresholds allow the hand to adapt grip pressure to object hardness — holding delicate items without crushing and heavier loads without slipping. Power-off self-locking holds position without continuous power, making it practical for sustained grasping tasks. Available in left and right configurations with RS485 or CAN control interface.

Key Features
  • 15N thumb / 10N per-finger grip force — 2.5× stronger than the RH56BFX; built for real grasping workloads
  • 6 micro linear servo actuators — compact linear drive architecture powering all 6 DOF
  • 6 integrated force sensors — real-time force feedback with configurable grip thresholds per finger
  • Absolute position sensors — precise positional awareness throughout every motion
  • 8 kg passive load capacity per finger — handles significant payloads without structural compromise
  • Power-off self-locking — holds grip position without power; no repositioning required on startup
  • ±0.20mm repeatability — sub-millimeter precision across all 6 DOF
  • RS485 or CAN control interface — select the protocol that matches your control stack
  • ROS / ROS 2 compatible — plugins available for direct integration
  • Left and right hand configurations — available as matched pairs for bimanual setups
