Auto-Erase

By: Nemo, Lauren, and Evan 

Problem: It takes too much effort to erase a whiteboard. We've been asked to make this job "lazy."

Solution: We've invented the Auto-Erase to allow you to erase a whiteboard in the most easy and efficient way. 

Precedents: Roomba, Squeegee, Dry Erase Spray, Windshield wipers, 

 

Our first prototype was made out of cardboard, magnets, sponges, and glue.

Auto-Erase works by using the two magnets to move the machine around the board to erase the marker. Here are some pictures of our first prototype. 

For our second prototype, we decided to change things up.  We used wood, wheels, and hot glue instead of cardboard. We decided to get rid of the idea of a roomba, and start over. Now, our invention is a sliding eraser that is attached to the whiteboard that moves back and forth to erase the marker. Here are some pictures of our invention:
