Help with robobutler project

[razatherogue]

so I'm trying to build the robot butler project from the raspberry pi website. I accidentally got a 4 motor chassis. And it's not working. Is it because I got the 4 motor chassis that it's not working or is it something else? It says wiimote connected when I run robot.py but then it just hangs. Nothing works.

Are you using 1amp powerbank or 2.1Amp?
4 motors draws more power, powerbank shutdown maybe?
