How do I power the robotic arm when it is mounted on a mobile chassis?

The robotic arm operates within a voltage range of 9–12.6V.

It can be powered using a 3S lithium battery pack that meets the required power rating.

A 3S Li-ion pack consists of three lithium cells in series (Series):

• Nominal voltage per cell: 3.7V
• Nominal voltage of 3S pack: 11.1V
• Fully charged voltage: 12.6V (4.2V per cell)
• Discharge cutoff voltage: 9V (3.0V per cell)

Ensure your battery and power system can handle the peak current of the robotic arm.

Check for bus communication interruptions.

The system contains four servos + one TTL Node (A) board — a total of five devices that must maintain stable bus communication.

If any device drops offline or cannot be pinged, communication may become blocked, causing certain movements to behave unusually slowly.
