An inexpensive way to introduce basic engineering, motors, circuits, and physics concepts
Bristlebots are small robots made by combining a toothbrush head and a vibrating motor. By changing the position of the pipe cleaner arms, they will travel in circles, walk straight lines, or scoot around randomly. No tools are required for building — the toothbrush heads come precut, and motor wires have exposed ends to connect to the battery.
- Kit includes everything you need to build 25 Bristlebots: precut toothbrush heads, double-sided tape cubes, vibration motors, batteries, googly eyes, and pipe cleaners
- Build time: 5–15 minutes per robot
- Ages 10+
