Build a Robotic Arm

Science Fair Project Idea

Engineering Design Process

Robotic arms have many uses, ranging from assembling things in factories to collecting soil samples on Mars to acting as prosthetics (artificial limbs) for humans. If you have ever wanted to build your own robotic arm, this project will guide you through the basics of designing and building a simple one. You can use this design as a starting point to design your own robotic arm and add your own features. Read more

Build a Simple Walking Robot

Science Fair Project Idea

Engineering Design Process

Humans are pretty good at building vehicles with wheels, but building machines with legs that walk like us is a lot harder! In this engineering project you will build a simple robot that walks using a single motor. How fast can you make your robot go? Read more

Build a Solar-Powered Car

Science Fair Project Idea

Scientific Method

Do you want to build a solar-powered car? How about enter it in a competition and race it against other people's designs? If so, this is the project for you! These instructions will show you how to get started building a solar-powered car that you can enter in a science or engineering fair. No experience needed. If you want, you can even compete in the Junior Solar Sprint, a regional competition for solar-powered cars. Get more information about your regional competition. Are you a… Read more

Build a Speedy Light-Tracking Robot (BlueBot Project #2)

Science Fair Project Idea

Engineering Design Process

Have you ever seen a cat chase a laser pointer or a flashlight beam? What if you could make a robot do that? In this project, you will build a robot that can automatically drive toward a bright light source. The robot uses a simple electronic circuit to track light, so there is no computer programming required! You can also do three other robotics projects using the same kit of parts, so this is a great way to get started with robotics before moving on to more advanced projects. Read more

Build an Adaptive Game Controller for a Raspberry Pi

Science Fair Project Idea

Engineering Design Process

People with limited mobility, especially in their hands, may not be able to use traditional video game controllers. Adaptive game controllers use a variety of peripherals, like larger buttons, foot pedals, or specialized joysticks, to let people with limited mobility play video games. This video shows how to build a very simple adaptive controller that works with Scratch games on a Raspberry Pi. Can you build an adaptive game controller for a hardware platform and game of your choice? If you… Read more

Build an Arduino Strobe Light for the Stroboscopic Effect

Science Fair Project Idea

Engineering Design Process

The Science Buddies project Build a Levitating Water Fountain with the Stroboscopic Effect shows you how to illuminate a dripping stream of water with a strobe light to make it look like the drops are hovering in mid-air. If you have not already, read the background section of that project and watch the following two videos. Make sure you understand frequency, period, and duty cycle before you proceed with this project. The project has you use a strobe light app on your phone. The advantage… Read more

Build an Obstacle-Detecting Walking Stick for Blind People

Science Fair Project Idea

Engineering Design Process

Many individuals who are blind or visually impaired use canes to navigate their surroundings, using their sense of touch to detect obstacles. What if you could create an electronic cane that emits an audible warning before coming into contact with an object? This project allows you to do just that by incorporating an ultrasonic distance sensor and a buzzer to alert the user of approaching obstacles. You can customize the cane by adding additional features or altering the design, such as using a… Read more

Build Obstacle-Detecting Glasses for Visually Impaired People

Science Fair Project Idea

Engineering Design Process

Many visually impaired people use canes to detect obstacles at ground level. What about detecting an obstacle at face level, like a tree branch? What if you need to keep both your hands free and cannot hold a cane? Solve both problems at once with these obstacle-detecting glasses! The glasses use an ultrasonic sensor to measure distance and a buzzer to alert the user of nearby objects. You can customize the design to add or swap out features, like using a vibration motor instead of a buzzer.… Read more

Build Your Own Crystal Radio

Science Fair Project Idea

Scientific Method

Have you ever wondered how a radio can grab signals that are transmitted through the air and convert them into sound? In this science project, you will build your own AM radio receiver from scratch and use it to listen to AM radio broadcasts. With your crystal radio you will be able to experiment with the circuit and the antenna to get the best reception. Read more

Building Personal Medicine Apps to Help Patients

Science Fair Project Idea

Engineering Design Process

Remembering to take medication or perform a test regularly, consistently, and at specific times can be difficult for elderly people with short-term memory loss, or teenagers absorbed in activities. With mobile devices becoming our constant companions, could a smartphone or tablet offer a solution? The Massachusetts Institute of Technology (MIT) has created a simple tool making it possible for anyone who has a computer and Internet access to create a reminder app. It is easy, quick, and… Read more
