Electrical Box

This was a more straightforward project focused on clean electrical organization, aesthetics, and ease of use. The goal was to create a protective, accessible, and visually appealing housing for each AKE60-8 Cubemars motor’s electronics, based on direct feedback from the electrical team. 

The electrical boxes were designed to house the ODrive motor controller, fuse board, and XT60 connector—one full set per motor. To determine layout, I created quick sketches in Onshape, placing components while accounting for wire slack, wire length, and connector positioning. I imported models of the actual electronics to accurately size the enclosures around them.

To ensure a dustproof and sand-resistant setup, each enclosure includes side panels secured with M3 screws that fasten into M3 heat-set inserts embedded in the base. The boxes are fully closable, preventing debris from reaching sensitive electronics during field use.

Aesthetically, I referenced the curved geometry used on the wrist’s motor plates and scaled it into the electrical box design to keep the form consistent across the arm. The rear face of the box includes a rectangular cutout, allowing the fuse board and ODrive controller to slide in without unsoldering wires, enabling easier repairs and upgrades. Wire routing holes are also included to direct cables cleanly to the motors and control systems. The right-side enclosure includes an extra compartment to mount a buck converter for the hand mechanism.
