Whiteboard Arena

This is an erasable flat surface that I used to test a variety of robots. I tested LEGO and Arduino robots in this arena. Could they detect a wall or a ball? Could they handle a corner of the walls? But I wasn't limited to that. I could draw a course and see how it navigated it. The ultimate in line following challenges. Can it handle a curve or a tight one? Can it follow a corner at any angle? How does it work with color? And then I could erase the challenge and create a new one. This whiteboard features a sturdy wooden frame. I over-engineer and build things strong. I sat this on a foosball table so I had a level field. It measures 49 1/4 x 30 by 3 1/2 inches. I envision that it could be used for anything that is used on a flat surface. A war zone and play army. A garden. Draw and edit on a large surface. A PCB at a large scale. The possibilities are endless. On the price I'm flexible. I know what it worth to me. What is it worth to you?
