Hello,

I'm entering into the robofest competition and I need some help. Basically I have to find the area of a black triangle taped onto a white table as quickly & accurately as possible. I'm going to use A=1/2B*a so I need my robot to find the base and the hight of the triangle.

I know I could use the motor rotations, but I was hoping for a quicker way to get the measurements I need. Could the Arduino use a camera or other sensors so my robot does not have to follow the edge of the triangle? Also money is not really an object, but I don't know to much programing for Arduino.

Any help would be appreciated!
