Developed by Beijing Inspire Robots Technology Co., Ltd., the RH56E2 Series is a high‑performance 5‑finger dexterous hand that combines 17 tactile sensors with 6 force sensors for unmatched perception and gripping precision. Available in left‑hand (RH56E2‑0L/2L) and right‑hand (RH56E2‑0R/2R) configurations, with resistive (T1) or capacitive (T2) tactile sensing options, the RH56E2 Series delivers real‑time tactile and force feedback for optimized grip control in industrial automation, healthcare, new energy, and service robotics applications.
Key Features
-
17 Tactile Sensors + 6 Force Sensors – Tactile sensors distributed across fingertips, finger pads, and palm provide real‑time tactile information, while force sensors in each finger deliver precise force feedback for adaptive, delicate gripping.
-
Human‑Equivalent Grip Strength – Thumb fingertip output force reaches 30N (approx. 3 kg), and four‑finger output reaches 28N (approx. 2.8 kg), enabling secure handling of objects across a wide range of sizes, shapes, and weights.
-
High‑Speed Articulation – Thumb lateral rotation range 75°~170° with speed >130°/s, thumb bending speed >130°/s, and four‑finger bending speed >200°/s for rapid, responsive grasping.
-
Power‑Off Self‑Locking – Maintains position when power is disconnected; absolute encoders eliminate re‑homing on power‑up.
-
Flexible Communication – Supports RS485, CAN, and Modbus TCP for seamless integration with a wide range of robotic systems.
-
Tactile Sensor Options – Resistive (T1, 0‑30N range, ≤5% FS accuracy) or capacitive (T2, 0‑20N range, ≤5% FS accuracy).
