Today I decided to do a remake of the EduBot robot I made a few years back, now that I have a Vex kit!

I never got anyone to program the EduBot, so now that I made this one out of Vex here is what I programmed it to do:
Four wheel drive both arcade or tank control (switchable)
Crab drive
Four wheel steering
To change the control type I used channels 5 and 6 on the Vex controller.
