The RH56BFX — widely known as the Pianist — is Inspire Robots' speed-optimized dexterous hand, built for applications where rapid, fluid finger motion is the priority. With a peak four-finger flexion speed of 570°/s, it is designed for high-frequency coordinated finger movement such as gesture interaction, musical instrument demonstrations, fast teleoperation, and robotics research.

Six integrated micro linear servo actuators drive 6 degrees of freedom across 12 joints, with built-in force sensors providing real-time feedback throughout motion. Power-off self-locking allows the hand to hold its position without continuous power, so no repositioning is required on startup. The RH56BFX is available in left-hand and right-hand configurations with RS485 or CAN control interface options.

Package note: This product is available in Without Wrist and With Wrist options. If your robot arm, humanoid platform, or teleoperation setup requires a mechanical wrist, choose the With Wrist package.
