Drive wheels

[pfortunejr]

How many drive wheels can be used on the robot????????????

I'm going to take a guess here and say as many as you feel you may need to use! (someone back me up though)

You can use any size and any amount of skyway wheels, and you can use whatever material from the additional hardware list to make your own wheels...

As long as your robot is under 130 lbs and inside the box.
