How to Order
Turn a brush into a robot! BrushBots are easy and fun to build and race. The tiny vibrating motor turns the bristles into thousands of little legs, then they scoot like crazy bugs. This amazing hands-on experience allows students to experiment with trial and error, learn from their mistakes, and understand the potential gaps between theory and practice.
Age range: 9 -14
Project time: 60 - 90 minutes
Area: Robotics, Engineering
Key concepts: Simple Electrical Circuits
Your kit includes:
- AA batteries (2)
- 2xAA battery holder
- 3 volt DC motor
- Scrub brush
- Glue stick, fasteners, and beads
- 2 Screws
You will also need the following supplies (not included in the kit):
- Electrical tape
- Square head screwdriver
- Scissors
- Optional: Materials to decorate your robot (googly eyes, pipe cleaners)
Follow these troubleshooting tips when using your Brushbot:
- If your Brushbot stops moving suddenly, check to make sure that one set of wires did not come loose. If you did not twist the wires tightly enough, the vibrations may cause them to come apart. If necessary, take off the tape, tightly re-twist the wires, and then reapply tape.
- As your robot wobbles around, some pieces may fall off. If necessary, use more tape to reattach them.
- Always turn your robot off when not in use to help conserve battery power.
Your robot probably did not move in a straight line. In fact, it probably buzzed all over the place, and crashed into things! This is because your Brushbot's movement is random. There is no computer "brain" telling the robot how to steer. More-advanced robots rely on computer programs to help them avoid crashing into things.
You will have the access to the free mini course "Build A Brushbot" and receive the "Certificate of Completion" after finishing the model throughout the course.
