Gripper Wiring

The wiring of the A4 robot arm takes place in the reverse order of the assembly. This way, the cables are bundles together at each joint until there is one cable bundle to plug in to the PCBA.

Solder Cable to Gripper Motor

One end of the cable is soldered to the motor terminals. The other end is a 2 position TE connector.
