Light Sensitive Bristlebot Kit - Create Your Own Bot - Explore The Simple Feedback Circuit Analog of Bacteria - Science Fair Kits by Eisco

Humans are complex organisms with highly evolved nervous systems. But believe it or not we are not the dominant species on the planet. In terms of both numbers and mass, bacteria take that award by a landslide. Bacteria have no brain and flagella provide their only motive force, so how are they able to succeed so stunningly? Turns out that they use random motion enhanced by analog feedback. This kit includes components for building a simple light-based bacteria model based on the bristlebot design. The bot moves randomly when there isn't enough light. When it wanders into a region with enough light it slows down and stops. In a classroom setting multiple bots will compete and will bounce each other out of the lighted region.

Kit is suitable for students ages 8 and up, with parental help (Ages 10+ without parental help).
