Wiring

After building the mechanical structure of the robot, connect the electrical components following this wiring diagram:

Joining the cables together

There are multiple ways to join the signal and power cables together. We provide our recommended ways for you reference.

For signal cables, we recommend directly solder them together and protect the solder joints with heat shrink tubes.

When first connecting power cables together, for easier debugging, the WAGO connectors can be used to quickly joining and detaching each actuators to the main power bus without soldering. They are available in multiple types, and we use both the two, three, and five ports on the robot.

For a more permanant build, we recommend to solder the cables together directly. by Will Donaldson provides a good guide on how to solder these thicker cables. Between the actuators, the cables can be connected with XT30 and XT60 connectors. We use XT60 to connect the main cable together, with each actuator connected to this main power bus using XT30 connectors.
