Manipulator Arm parts diagram: 1 shoulder joint, 2 arm link, 3 elbow joint, 4 wrist module, 5 gripper, 6 wire bundle. 166 parts in 6 top-level items.
Manipulator Arm parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Shoulder Joint 4 parts 1× Highest-torque joint of the arm, a harmonic-drive actuator at the turret base providing azimuth and shoulder pitch.
2 Arm Link 2× Upper and forearm tubes
3 Elbow Joint 4 parts 1× Mid-arm pitch actuator sized at roughly half shoulder torque.
4 Wrist Module 4 parts 1× Pitch and continuous rotate
5 Gripper 5 parts 1× Parallel-jaw end effector with force feedback, closing to 200-600 N yet controllable gently enough to pick up a wire.
6 Wire Bundle 1× Internal harness
