Building Junkbots—Robots from Recycled Materials
- Understand the difference between open, closed, and short circuits.
- Apply the engineering design process to iteratively test and improve a robot.
OverviewJunkbots are easy-to-build robots that you can make using a simple circuit and some recyclable materials. In this lesson, your students will learn about engineering design as they compete to build the fastest robot. No previous robotics experience is required!

To build a junkbot you will need a motor, a battery pack, and two double A batteries. Other household items include a cardboard box, glue, rolls of tape, scissors, plastic cup, plastic bottle, cork, popsicle sticks, paper clips, plastic straws, metal cans, and a cardboard tube.
For each student or small group of students building a robot, you will need these items in the Bristlebot Robotics Kit from our partner Home Science Tools (also available as a Classroom Kit specially priced for teachers):
For the entire class, you will need:
