Brushbot Build

Some of the kids try to figure out the effects of toothbrush bristles, we had 3 different designs and a few added toothpick stabilizers. Several tried 2 vibrating motors and different sized batteries, which could change the Brushbot’s path and speed.

Our Brushbot build this last Sunday turned out well. This is a popular kids project, to the point now where you can even buy kits to make them. We did it the old fashioned way with a toothbrush, pager motor, battery and double-sided tape.  Thanks to Dollar Tree and a bulk order of motors from China, they cost less than $1/piece and many of the kids made them with their own toothbrush!

An old hexbug track made a good testing course for the Brushbots, although several kids also used notebooks and other obstacles on a large flat table to make a track to test different Brushbot configurations.

If you’re like many parents looking for summer opportunities for your kids, this coming Saturday February 21rst, the 26th Annual Summer Camp Fair will be going on from 11-3 in Indianapolis at the Fashion Mall. I try to keep the events page updated with other regional STEM opportunities, if you hear of something you feel others would be interested in let me know.

Also a few of the adults have started building a Robobrrd, a felt-covered interactive robotic bird made of popsicle sticks that uses an arduino micro-controller. At this point it’s still for adults (or older kids) as we figure out how it could best be made by the larger group. Feel free to join us, you’ll be helping other kids down the road. We’re meeting on Tuesday nights at 7 pm, 605 Crown Street at least through March. Again you can always check the events page.
