Hi,
Just finished building R2-D2 and tested most functions which seem to work but the right leg motor does not move. Have taken apart and checked all connections from the right leg to the MCU and sensor board and they are definitely plugged in. Tried connecting the motor itself to the test PCB and it turns fine. I'm suspicious of the MCU at the moment.


Thought it might be one of the leg sensors. Disconnected the left leg sensors to see if that would stop the left leg motor functioning and it didnt. Tried the same on the right leg and still the same - no movement. Any suggestions would be gratefully received?

In the mean time i'm going to continue testing other functions to see if anything isn't working but I dont think so, head moves left and right, light sabre, projector, sound, status lights etc work.

Thanks Paul (frustrated R2D2 builder)

Hi Paul

Could you check the pins in the MCU are straight and that the metal contacts in the lead plug are seated fully in there housing.

The right leg motor has the encoder that starts R2 at the initial startup. If it wasn’t working at all then nothing else would startup and not operate. Check all the cables, make sure they are connected with pins in place, no bent ones. Also check cables for broken solder joints.
