As robots grow, power wiring becomes the hidden reliability problem. A power distribution board or plate makes every rail visible: battery input, motor voltage, 5V logic, servo power and emergency stop.
You do not need a custom PCB at first. A fused terminal block, buck converters and labeled wiring can solve most prototype issues.

Terminal blocks, fuses and buck modules.
Use after current needs and connectors are proven.
Not always. Separate regulated rails are usually enough.
It should remove motor power, not just ask software to stop.
It prevents accidental sensor or servo overvoltage.
