Build a Jumping Robot

Science Fair Project Idea

Engineering Design Process

Can you build a robot that hops like a frog? In this engineering project, you will learn how to build a simple robot that uses the energy stored in a stretched rubber band to jump. You will use the engineering design process to try to make your robot jump higher and farther. How far can you make it jump? Read more

Build an RC Boat

Science Fair Project Idea

Engineering Design Process

Do you like playing with radio-controlled (RC) toys like cars, planes, and boats? What if you could build and customize your own? In this engineering project, you will learn how to build your own RC boat using an Arduino and a plastic food storage container. Read more

Building "junkbots" is a fun activity where you can turn recycled materials—like plastic bottles and cardboard tubes—into robots! This is a great activity for a classroom or a group of friends, because you can race your robots against each other and even make them sumo wrestle. You do not need any previous experience with robotics to build junkbots. A Science Buddies kit is available with all the electronic parts you need, including motors, batteries, and clear instructions for how… Read more

Make an Origami Robotic Gripper

Science Fair Project Idea

Engineering Design Process

Do you like making paper airplanes? What about origami animals? Have you ever thought about making a paper robot? In this engineering project, you will make a three-dimensional robotic gripper that starts out as a single flat sheet of paper! Try it out—see what objects you can pick up with the gripper, then see if you can improve the design. Read more

3D Print a Drone Frame

Science Fair Project Idea

Engineering Design Process

Drones come in all shapes and sizes. In this engineering project you will design and 3D-print your own frame for a miniature drone. Read more

Racing Bristlebots: On Your Mark. Get Set. Go!

Science Fair Project Idea

Scientific Method

Have you ever wanted to build your very own robot from scratch? Bristlebots are a cheap, easy, and fun-to-build robot made from the head of a toothbrush, a battery, and a small motor. Once completed, they buzz along the top of a table like bugs. How can you make a bristlebot go faster? In this project, you will build bristlebots from two different types of toothbrushes, and race them against each other to find out. Read more

Brushbots are a simple, fun type of robot that you can build out of arts and crafts materials. They are easy to build and you do not need any previous experience with robotics. You can build them yourself, build two robots with a friend and race them against each other, or even make them sumo wrestle! Go to the Materials section to see what parts you need to build a brushbot, and see the instructions for a step-by-step guide on how to build one. Read more

Squishy Robots: Build an Air-Powered Soft Robotic Gripper

Science Fair Project Idea

Scientific Method

When you think about robots, chances are they are contraptions that you have seen on TV, in movies, or even in real life — and they are usually made of metal. What if you could make a soft robot that could bend, twist, or squirm like an octopus or an earthworm? Researchers at Harvard University have done exactly that, developing soft robots made of rubber and powered by air instead of electricity. In this project you will use their designs to build a soft robotic gripper of your own. Read more

Build a Motion-Activated Guard Robot (BlueBot Project #1)

Science Fair Project Idea

Engineering Design Process

Do you ever wish you could hire someone to guard your favorite toys, or keep certain people from coming into your room? What if you could make a robot to do it for you? This project will show you how to build a simple security robot controlled by a motion-detecting sensor. When someone comes near your valuables or enters the room, the robot will spring to life and (hopefully) scare them away! Read more

Build a Simple Steerable Robot

Science Fair Project Idea

Engineering Design Process

Beginner robotics projects like the Art Bot and Bristlebots are fun, but the robots wobble around randomly and cannot steer. If you are ready for a robotics project that is a little more advanced (that does not require any programming), try this one out! You will build your own steerable robot with a wired remote control.
