The CYBOT problem pages - Motor Checking
Quite a few people raise questions regarding motor operation.
Before taking cybot apart or getting violent with it, check the batteries!
MOTOR WIRING AND CONNECTIONS
ABOVE: CORRECT motor placement.
ABOVE: CORRECT plug position and wiring.
Please observe the following:
If any are incorrect, you may get reversed motor operation.
Your options are:
Remove the motor PCB screws and withdraw the pcb. Plug the motor test board in.
Ensure that the connections on the PCBs do not come into contact with metal or other pcb's
To be sure, remove the motor from the gearbox and try again.
If the motor begins to spin, strip and rebuild the gearbox.
If the fault moves to the other motor, the motor pcb may be faulty.
ENSURE CYBOT IS SWITCHED OFF
When you turn the wheels, or push cybot along, the motors act as small dynamo's.
As such they generate electricity, injecting current into the motor board - this can damage cybot.
The advice here involves slowly turning the wheels for a few moments.
Swap the connections as above and try again.
If the other motor bcomes stiff to turn, the motor PCB may be faulty
If a motor fails to operate where the other motor did, the motor has a fault.
Carefully check the connections and wires for signs of broken off wires.
