I just got a GoPiGo, set it all up as per the instructions. Got the GoPiGo software using “git clone …” and updated the firwmare to 1.1. When I run basic_test_all.py and try moving forward only one of the motors moves. Same for motor_fwd(). If I disconnect the good motor and put my ear close to the one that doesn’t move I can hear it buzzing/humming. So it is connected and seems to be trying to move, but not succeeding. I tried swapping the motors and the good motor still works and the bad one still doesn’t. So I suspect that the GoPiGO is all fine and there is just something wrong with that motor itself.
I read through http://www.dexterindustries.com/forum/?topic=power-supply-issues and even tried the set_speed(150) suggested in there, but I think my problem is a bit different, since it never worked at all, even in basic_test_all.py.
So do I need to replace the motor or is there something else I can try first? Do you know the manufacturer and model number of the motor? Perhaps I can buy one of those separately.
