Step 9A: Attach the Shoulder Yaw Joint Plate
Orient part 400_05A on actuator ID 15 and secure it to the actuator with eight threadlocked M3x12 flat bolts.
Parts needed
| Part | Count |
|---|---|
| Current shoulder assembly | 1 |
| 1 | |
| M3x12 Flat Bolt | 8 |
| Threadlocker | As needed |
Instructions
Now move Sub Assembly B upward so that the Left Shoulder Yaw actuator (ID 15) shaft is facing the ceiling.
Take part and align it with the holes on the surface of Sub Assembly B 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 – M3x12 Flat Bolts 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 each of the 8 – M3x12 flat bolts in a star formation,
- apply threadlocker,
- then tighten them back to secure Part and the actuator together.
How is this guide?
Step 8B: Attach the Opposite Shoulder Plate
