Doodle Bots

We had such a great time exploring how we could create robots with items that we could find within our own home.  We used an electronic toothbrush, washable markers, a pool noodle, and rubber band. 
​
We were able to attach the markers to the outside of the pool noodles with the rubber band and insert the electric toothbrush into the center.  Three markers seemed to be the optimum number of markers. The students choose their colors and let their robots do their thing. With trial and error students were able to decide what worked and what did not work.  It was so much fun, an easy setup, and only a little mess when the doddle bots had a mind of their own.
