Welcome to the forums.
I'm hoping that the problem is that you're using the robot with the Tecknet USB powerbank, and that you've forgotten to flick the switch on the Mini Driver to 'on'. The USB powerbank gives good battery life for the robot, but this is a bit of a pitfall for people just getting started I'm afraid.
Hope that helps.
Regards
