Step 1: Parts/System Break Down
Arduino Mega Protoshield, with 2 mini breadboards and jumpers
3 VEX motors
BlueSmirf Bluetooth Adapter (located in the yellow VEX case with antenna)
RoboRealm Vision Software
VEX linear sliders
VEX Rack and Pinion gears
VEX 9.6V Battery
4 VEX small wheels
Vex metal, screws, etc.
This project is made up of two main sections. The first section is the actual robot. The robot in theory is somewhat simple. It consists of a base with two wheels which rides on a whiteboard track. The base design allows the robot to cover the entire x-axis of the whiteboard. To move on the y-axis, the robot uses linear sliders to move an arm up and down. Attached to the end of the arm is a dry-eraser that does the actual erasing.
Building the robot is not hard. It just consists of 2 motors which each respectively drive 2 small VEX wheels.
