Step 8: Attach the Shoulder Yaw Joint Plate and Shaft Mount
Secure part 300_05A to actuator ID 20 with eight threadlocked M3x12 Flat bolts, then route the cable through part 300_06B and secure it to the actuator shaft with six threadlocked M4x20 Socket bolts.

| Threadlocker | As needed |
Instructions
Now move Upper Arm Assembly upward so that the shaft of the Right Shoulder Yaw (ID 20) is facing the ceiling.
Take part and align it with the holes on the surface of Upper Arm Assembly around the actuator shaft. Part has 1 protrusion on its edge, it is important that this protrusion is facing toward you like in the visualization. Make sure this is positioned correctly, else your arm will be locked wrongly.
Take 8 of and lightly tighten it into the 8 holes on Part to align with the threaded holes on the actuator.
After the parts are aligned:
- remove 8 of one at a time in a star formation,
- apply threadlocker,
- then tighten them back to secure Part and the actuator together.
Take Part and align the 6 holes on the part with the actuator shaft holes. Also route the cable form the hollow shaft of the actuator through the center of part .
Take 6 of and lightly tighten each one into the holes to align part with the actuator.
After the parts are aligned:
- remove 6 of one at a time in a star formation,
- apply threadlocker,
- then tighten them back to secure Part and the actuator together.
How is this guide?
Step 7: Connect and Join the Shoulder Assemblies
Connect the XT30 (2+2) connector to actuator ID 19, solder the corresponding cable conductors from actuators ID 18 and ID 19, and join the shoulder and upper arm assemblies with plates 300_03A and 300_01A and threadlocked flat bolts.
Step 9: Install the Elbow Actuator and Route Its Cables
Connect the XT30 (2+2) cable connectors to actuator ID 21, seat it in part 300_15C, and route both cables through their designated openings.
