> [!IMPORTANT]
> **Assign actuator IDs before assembly**
>
> Assign and verify all 25 actuator IDs before assembling the robot. The robot will not work correctly with missing or incorrect IDs. IDs must be assigned one actuator at a time on the bench; you may need to disassemble the robot if you skip this step. See [Assign Actuator IDs](https://docs.menlo.ai/asimov/1/build/assembly-preparations/assign-actuator-ids.md).

## Parts needed

| Part | Count |
| - | -: |
| Current assembly from Step 5 | 1 |
| `500_07C` | 1 |
| `500_04C` | 1 |
| M4x14 Socket bolt | 17 |

## Instructions

1. Take the current assembly and lay it flat on the surface such that part `500_12A` is facing upward toward the ceiling and toward you.

2. Take part `500_07C` (it should have 8 holes, not to confuse with part `500_04C`) and prepare to align to `500_03C` as shown below.

3. Take **8 of** M4x14 Socket bolts and lightly tighten them into the holes on parts `500_07C` to align the part to the threaded insert on part `500_03C`.

4. Take part `500_04C` (it should have 9 holes) and prepare to align to `500_03C` as shown below.

5. Take **9 of** M4x14 Socket bolts and lightly tighten them into the holes on parts `500_04C` to align the part to the threaded insert on part `500_03C`.

6. Once both parts are aligned, fully tighten all **17 of** M4x14 Socket bolts in a star formation to secure part `500_07C` and part `500_04C` to part `500_03C`.
