J2 cable breakage

[Hardware-Hero]

Describe the problem you got

A problem occurred in which the wiring of the J2 motor, which runs together with the J3 cable through the rotational center of J2 toward the body side, got caught on the bolt located near the output shaft of the J2 motor (see the figure below) and broke.

This issue arises from the structural design in which the J2 wiring is routed through the output shaft side of J2, and therefore the design needs to be fundamentally revised to prevent recurrence.

[Hardware-Hero]

Bringing wiring close to large rotating parts poses a risk of entanglement, so we changed the cable routing.
By rerouting the J2 cables directly from the rear side of J2 toward the main body, we avoided the risk of entanglement.
Along with this change, we redesigned the shape of the J2_B cover accordingly.
