First off, thanks for the great job on the GoPiGo. Generally, the build and first use went fairly smoothly, although I’ve encountered all of the minor issues that others have posted about. Managed to figure out how to get around these and get control of my GPG via wifi.
The problem that I’m seeing now is that the servo doesn’t move consistently. I’m running the servo_test.py program. I’m not sure what the problem is, but the movement is jerky: instead of moving to a position directly, often the servo moves forward, then jumps backwards, before it stops for each increment of the servo angle. I’ve modified the test program to increase the time.delay between increments of the angle just to be sure that this is what was happening.
I expect the movement to be choppy, but didn’t expect the movement to be back-and-forth.
Any ideas? Maybe a bad servo?
