A robot power board should make battery, logic, servo and motor rails explicit and protected.
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.
Battery short protection
Clean power fanout
Logic rail
Separate servo rail
Load monitoring and stall detection
Hard motor disable
Terminal blocks, fuses and buck modules.
Use after current needs and connectors are proven.
Treat the generated output as a prototype plan, not a certified product. Body-adjacent, high-voltage, optical-energy and mobility builds need qualified review before real-world use.
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.
