How Fast is Automatic Braking?

Science Fair Project Idea

Scientific Method

How fast can a human driver react and hit the brakes when there is an obstacle in the road? Can autonomous cars react more quickly and make the road safer for everyone? In this project you will build your own Arduino robot and test human braking versus automatic braking as the robot drives toward an obstacle at full speed. Read more

Human-Robot Interaction: Do Looks Matter?

Science Fair Project Idea

Scientific Method

Do you think robots are cute? Funny? Scary? How do robots make you feel? What words would you choose to describe a robot? Find out how people react to robots by building and decorating your own robot in this science project. Read more

PID Controller Tuning for a Drone

Science Fair Project Idea

Engineering Design Process

Note: to do this project you will need the DIY Mini Drone Kit, available from our partner Home Science Tools®. An Arduino must be purchased separately. The Electronics Kit for Arduino, available from our partner Home Science Tools®, contains the additional parts you will need, including an ultrasonic sensor. The program in the DIY Mini Drone: Arduino™ Altitude Control project uses a proportional controller to control the drone's altitude. A potentiometer is connected to one… Read more

Racing Drones: Does Practice Make You Faster?

Science Fair Project Idea

Scientific Method

Have you ever flown a drone? Did you find it easy the first time you tried? In this project, you will fly a drone through an obstacle course and measure how practice changes your performance. Will practice help you finish the course in less time? Try it out! Read more

SeaPerch: An Underwater Robot

Science Fair Project Idea

Engineering Design Process

Underwater robots, or remotely operated vehicles (ROVs), help us explore areas of the ocean that can be dangerous for humans. They can provide valuable scientific information about deep-sea life and ocean climate. However, you do not need access to the ocean to build and test your own ROV. If you have ever wanted to build your own ROV but were not sure where to start, the SeaPerch platform is a great option. You can purchase a complete kit with all the required parts and follow the detailed… Read more

Squishy Robot Simulator

Science Fair Project Idea

Scientific Method

What do an octopus, an elephant's trunk, and an earthworm have in common? They are all squishy, bendable and flexible because they do not have any bones inside. You might not typically think of robots as "squishy," but scientists are increasingly trying to create soft robots that look and move like animals. In this project you will use a "soft robot simulator" to design and race your own squishy robots. Can you come up with the fastest design? Read more

Stair Master: Build an All-Terrain Robot

Science Fair Project Idea

Engineering Design Process

Have you ever tried to ride your bike up a flight of stairs? Vehicles with wheels are great at traveling on paved roads or flat ground, but when it comes to stairs or uneven ground in the woods, wheels are not always such a great option. Inspired by real-life all-terrain robots, in this engineering project you will design and build a LEGO® robot that can travel over bumpy ground, through your yard, or even up a stack of textbooks — and almost anything else you can think of!

Take a Hike: Train Your Robot Dog to Walk with a Virtual Leash

Science Fair Project Idea

Scientific Method

Have you ever walked a dog on a leash? Depending on how well-behaved the dog is, it can be very easy or very difficult. It would be great if you could tell your dog exactly how to behave, right? With that in mind, in this project you will build a robotic dog using a LEGO® Mindstorms® kit that you can teach to "walk" using the beam from a flashlight as a virtual leash. But your robot dog will not know how to walk on a leash on its own — you will have to "train" it, just as you… Read more

Use the Force! Push & Pull Robots With an Invisible Force

Science Fair Project Idea

Scientific Method

If you have seen any of the "Star Wars" movies, then you probably remember when Jedi knights like Luke Skywalker and Obi-Wan Kenobi used "The Force" to push, pull, and even throw objects — including some helpless battle droids. Have you ever wished you could do that in real life? In this robotics project, you will build and program a LEGO® robot that you can push and pull using an "invisible force" — almost like a real Jedi! We make no promise that you will be taking down the… Read more

What Sensors Are Best for Self-Driving Cars?

Science Fair Project Idea

Scientific Method

Self-driving cars use a variety of sensors to evaluate and navigate their environment. Each type of sensor has advantages and disadvantages. In this project you will evaluate two common types of distance sensor (ultrasonic and infrared) and compare their performance in different scenarios. Read more
