Light Sensitive Bristlebot Kit

Create a light-sensitive bristlebot that mimics simple feedback circuit analogs of bacteria.

• Build a simple light-based bacteria model based on the bristlebot design
• Allows students of all ages to explore and visualize the structure and processes of random motion and analog feedback
• Kit includes everything needed to construct 1 bot, instructions for assembly and experimental activities
• An excellent activity for classrooms and at home
• Each kit engages learners to discover new ideas about the physical world through assembly and play

Humans are complex organisms with highly evolved nervous systems, but bacteria are by far the dominant form of life on the planet. 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.

Kit includes: (2) toothbrush heads, (1) 25-pin micro breadboard, (1) 2N3904 NPN bipolar transistor, (1) CR2032 3V lithium coin cell battery, (1) micro 3V DC vibration motor, (1) 5539 photo resistor, 1×2" permanent mounting tape, 0.07 oz single-use superglue tube, (4) adhesive-backed googly eyes, (2) bare metal paperclip, cardboard storage box, and instructions for assembly and experimental activities.
