Science Fair Project Idea
thumbnail In the animal kingdom, many different critters use whiskers to help them find their way around in the dark, through murky waters, or even to help them hunt prey. Whiskers can be very useful when the animals can't rely on sight. Did you know that you can also build a robot that uses whiskers to find its way around? This science project will show you how to build a simple robot that uses whiskers as "bump sensors" to help the robot detect when it is about to bump into an obstacle, so it can turn… Read more

Safety Short circuits can get very hot and present a burn hazard. Be careful to avoid short circuits when building your robot. The "whiskers" used in this project are made of narrow wire and should be handled carefully. See the Procedure for more information.
Science Fair Project Idea
thumbnail 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
thumbnail If you have ever tried to hit a target (such as a trash can) with a wad of paper, you know that aim is everything. But it is not always easy to get it right every time! Missing is not that big a deal with a wad of paper, but what if you were in an invading army in the Middle Ages, using a catapult to hurl huge stones and knock down castle walls? For a successful invasion, it would be important to know exactly how far, and how reliably, a catapult could launch a projectile. In this project you… Read more

Science Fair Project Idea
thumbnail 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

Science Fair Project Idea
thumbnail This project is a follow-up to the Science Buddies project , which shows you how to build a basic infinity mirror using light emitting diodes (LEDs) and arts and crafts materials. What if you wanted to build an infinity mirror that could change colors, like the one in Figure 1? [[ Image [] Figure 1. A color-changing infinity mirror. [] Image ]] You can do this by using special RGB (red, green, and blue) LEDs. Just like the pixels on a TV or computer monitor, an RGB LED actually… Read more

Science Fair Project Idea
thumbnail 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

Science Fair Project Idea
thumbnail You probably use batteries to power different devices every day, ranging from toys to TV remotes, without giving it much thought. Figure 1, below, shows some common types of batteries. Eventually the batteries will die and you have to replace them with new ones (or recharge them if they are rechargeable batteries). How much do you actually know about how batteries work? This abbreviated project idea will give you some suggestions to investigate how batteries perform in common household… Read more

Science Fair Project Idea
thumbnail Following a simple black line seems pretty easy, right? But think about it; how do you know what is the line and what is not the line? What if you wanted a robot to follow that line? How would it know what you wanted it to follow? Robots can use simple techniques to sense their surroundings and change their behavior based on what they see. In this engineering project, you will build your own robot that will follow a path without using complicated electronics or programming. Read more
