Science Fair Project Idea
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

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!

Science Fair Project Idea
In the mid-20th century, people thought of robots as futuristic tools. But in the 21st century, robots are not a figment of our imaginations, but are a part of our reality. Robots even perform tasks that humans can't do. In this engineering science fair project, you will use LEGO Mindstorms to build a robot that is fast, lightweight, and stable. Who knows? You might end up building a robot that does housework or even your homework! Read more

Science Fair Project Idea
Do you think it is possible to build a robot you can steer, without programming a computer to tell the robot what to do? Believe it or not, it is! In this engineering project, you will build a robot using a simple electronic circuit that steers the robot left or right to make it follow a bright light. Then you will make some adjustments to the robot to see if you can improve its steering. How well will you be able to control your robot? Read more

Time Required Average (6-10 days)
Prerequisites While no previous electronics or robotics experience is required to do this project, it will be helpful if you are familiar with basic circuit concepts and with using a breadboard. The Bibliography section in the Background tab has many tutorials you can use to get started.
Material Availability This project requires specific circuit components from an electronics vendor. See the Materials list for details.
Cost Average ($40 - $80)
Safety Short circuits can get very hot and present a burn hazard. Be careful to avoid short circuits when building your robot. See the Procedure for more information.

If you ever rode in a cable car, ski lift, or gondola, you know they make moving over obstacles like lakes, valleys, rivers, or even up steep mountains seem easy. Though it would be pretty difficult to build a full-size cable car in your home, if you have a Mindstorms® kit, you can build a working-model cable car of your own. The engineering challenge is to build a LEGO® cable car that can travel across a string you have suspended somewhere in your house (between two pieces of… Read more

Time Required Short (2-5 days)
Prerequisites You should be familiar with programming for LEGO Mindstorms to do this project.
Material Availability This project requires a LEGO Mindstorms EV3 kit (available from [# Link Name="Amazon.EV3" Value="HtmlAnchor" #]) or a LEGO Mindstorms NXT kit.
Cost Very High (over $150)
Safety Make sure your cable car string is securely attached to a heavy object (like a table or large chair) at both ends. The Mindstorms bricks are heavy, and could fall and damage your LEGOs or other objects if the string is not securely attached.
Science Fair Project Idea
Sometimes engineers get ideas to build robots from animals in nature. There are robot dogs, robot snakes, robot birds, robot cheetahs, and even tiny robotic insects! In this science project, you will build a robot insect of your own. The robot will automatically drive toward a light source, mimicking a behavior called phototaxis, seen in some insects. You will build your own robot and then make adjustments so it can reliably drive toward a light. Read more

Cars that can drive themselves might sound like science-fiction, but they are a reality. Self-driving cars are cars that use sensors and computer programs to automatically drive on roads, without intervention from a human driver. However, the cars still have to follow all the same rules of the road as human drivers, including staying in the correct lane, obeying road signs and traffic lights, and avoiding obstacles like potholes or fallen tree limbs. In this project you will build a simplified… Read more

You have probably heard about using renewable energy sources like wind and solar power to provide electricity to homes and buildings, as well as hybrid or fully electric cars that use less (or zero) gasoline. But what about solar-powered robots? As robots become more common, it is increasingly important to use "green" energy sources to power them. In this project, you will build and test a popular robot called a bristlebot — a tiny robot made using toothbrushes—that can operate on… Read more

In our , you were challenged to use the VoxCAD software to design the fastest possible robot using different materials. However, we did not ask you to think about one big thing — efficiency. It is great to design a robot that is very fast, but what if it also consumes a lot of energy? Engineers must consider this when designing robots in the real world — robots that use more energy to move will drain their batteries faster, which can be a problem. This is similar to the concept of… Read more
