Take a look to :"My B-robot lacks of power or fall without reason" here

Maybe the stepper motors you are using demand more current to deliver enough torque

I bought the stepper motors and drivers from JJRobots, so I assume they will work correctly. However, I will take a look at the article suggested and see what happens.

Tried everything, including powering the robot with my external supply. The robot just makes a whining sound, and when it does eventually stand up, it will thrash around for a few seconds then fall over. Frankly I'm disappointed with this thing, and will probably trash it and start again with a new design, not using the Brainshield. I have a feeling the brainshield and/or software is responsible - I have replaced everything else without success, so it cannot really be anything than that.
