This is used for backing up. I might edit it to add a motor.
used to be used as a flashlight in dark missions or to follor a line.
*test mat included in regular mindstorms nxt 2.0.
**mes and origional mindstorms set I don't have the test mat included
Used for not bumping in the front. You could add a mechanic with a third motor
Like I said at the top, you can use this to edit your stuff. Hereyou have an 2x2 wheel drive like a tank. For you profesional mindstormers whoknow what they're talking about, you can comment on how 2x2 wheel drive is not good or having a third extra motor is not good. please I need help on this!
