Disobedient Eddie

I had driven Eddie with the native Parallax dashboard program:

I have now a problem with the motor drives. Sometimes Eddie won't go forward, then it just turns and eventually stops and combination of all of them. Disobedient kid.... I hope Eddie will grow up...

Several resets and it worked OK for a while. I replicated the problem also with the Parallax monitor program.

Sensors are working OK. See the right sensors on the picture, that detected the water container
in front.

Possibly I have just lost something and then blaming Eddie...
