5kg Linear Actuator Humanoid Robot Arm

1. Hybrid Actuator Configuration Design

The single arm employs a hybrid configuration combining HJL linear actuators and MJBX force-controlled rotary actuators .

The joint modules for the 7 axes are:

• Axes 1–3: MJB20T
• Axis 4: HJL12
• Axis 5: MJB14T

• Axes 6–7: HJL08

2. Core Specifications

• Single arm weight: 10 kg
• Payload capacity: ≥5 kg per arm

• Arm reach: 642.4 mm

3. Flexible Configuration

Each actuator includes a single-axis force sensor, with optional six-axis force sensor and dexterous hand at the end-effector.

4. Servo Drive System

Supports real-time communication via EtherCAT and CANopen protocols.
