Project Idea
thumbnail Have you ever heard of the NASA Mars rovers Spirit, Opportunity, and Curiosity? How about the "bomb squad" robots that police and the military use? These are places that are hard for us to reach (Mars), or dangerous for us to be near (explosives). Because the human operators are usually far away from the robot, driving one is different from driving a car. Operators rely on information sent back from the robot, including pictures and video. In this project, you will build your own simple… Read more

Project Idea
thumbnail In baseball, coaches use hit charts to track the results of every hit each player makes, giving a measure of the player's performance. Have you ever wondered what things affect where a baseball goes when a player hits it with a bat? In this project you will set up an experiment to hit a ping pong ball in a controlled manner using a toy catapult, then learn about the physics of baseball by making your own hit chart. Read more

Safety Never launch projectiles at people or animals. Be careful not to get your fingers caught in the moving parts of the catapult.
Project Idea
thumbnail Are you an artist, or do you enjoy the process of making art? What kind of art do you create? Do only humans make art? Not always. Robots can create art, too. Robots can be programmed and "taught" to do all kinds of things, such as delivering medications to hospital patients or putting together a car on an assembly line. The Vangobot™, shown in the video below, paints pictures with brushes and paint, and in a distinct, unique style - just like a human artist. Watch this… Read more

Time Required Long (2-4 weeks)
Prerequisites A basic familiarity with programming is needed to do this project.
Material Availability

This robotics engineering project requires that you purchase VEX® robotics materials. See the Materials tab for a suggestion of some VEX® parts to use. With a little problem-solving, you may be able to substitute another robotics platform.

The RobotC software needed to program the VEX system is Windows based. If you are using an Apple computer you will need to use visualization software such as VirtualBox or VMware®.

Cost Very High (over $150)
Safety Use caution with tools when assembling the robot. Minor injury is possible.
Project Idea
Here's a fun project idea to learn about compression forces. For this experiment you'll need some empty toilet paper tubes, masking tape, sand (or table salt), pebbles (or marbles), a funnel, a cardboard box, and a sturdy chair to help you balance while testing the column. Seal one end of the tube with masking tape. Use the funnel to fill the tube with sand (or salt). Seal the other end with tape. Place the tube on end inside the paper box. Place the chair with its back to the box and hold… Read more

Project Idea
thumbnail Watching professional racing-car drivers compete can be thrilling. The high speeds that racing cars can reach — up to 200 miles per hour (mph) and more! — put some unique demands on the vehicles. For example, to withstand high temperatures, the tires must be inflated with nitrogen gas, instead of air as with normal car tires. This enables the drivers to have better control over steering their cars as they race around the track. In this sports science project, you will inflate… Read more

Time Required Short (2-5 days)
Prerequisites None
Material Availability A helium tank is required to do this science project. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety Follow all safety precautions when using the helium tank and working with helium gas, as described on the tank's packaging.
Project Idea
thumbnail Have you ever seen moths buzzing around bright lights at night? What about animals that always crawl into dark places, under rocks or furniture? This type of behavior is called phototaxis — movement toward (or away from) a light source. In this project you will build your own biologically inspired robot critter that mimics this behavior. Basing your design on the popular and simple BristleBot robot, you will make a robot with two light sensors for "eyes" and two motors that help it steer… Read more

Time Required Average (6-10 days)
Prerequisites Some familiarity with electronic circuits and using breadboards will be very helpful, though not required, for this project. Using a soldering iron is also helpful but a work-around is offered in the Procedure.
Material Availability This project requires certain parts from an electronics store or online retailer. See the Materials and Equipment list for details.
Cost Average ($40 - $80)
Safety If you use a soldering iron for this project remember that soldering irons get extremely hot and can cause burns if they touch your skin. They can also become a fire hazard if left unattended. Science Buddies recommends using lead-free solder, especially in homes with pets or small children.
Project Idea
thumbnail 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

Time Required Average (6-10 days)
Prerequisites Familiarity with VoxCAD software — we recommend completing our [# ProjectIdea Name="Robotics_p016" Value="HtmlAnchor" HtmlText="introductory VoxCAD project" #] first. Basic knowledge of the concepts of energy consumption and power, or a willingness to learn them.
Material Availability This project requires the free VoxCAD software and a computer running Microsoft® Windows®.
Cost Very Low (under $20)
Safety No issues
Project Idea
thumbnail You probably know that turning off the lights and the water, and not wasting paper are all ways to help the environment and conserve our resources. Did you know that another way is to use fuel cells? A fuel cell is a device that converts the energy in chemicals to electricity and it creates no pollution. The starting chemical does not have to be something complex — in fact you it can even be water! In this science fair project try your own hand at converting water to electricity with the… Read more

Time Required Long (2-4 weeks)
Prerequisites None
Material Availability Specialty items required. See the Materials and Equipment list for details.
Cost High ($100 - $150)
Safety To do this science fair project, you will need to electrolyze water into hydrogen and oxygen. Hydrogen is flammable, so keep the fuel cell and hydrogen storage tank away from sparks.
Project Idea
thumbnail Did you know that throwing, kicking, and punting a football all involve the science of projectile motion? A star NFL® quarterback, kicker, and punter each need to have a very good understanding of how a football moves through the air in order to help them win games. In this science project, you will set up a rubber band-powered catapult to represent a field goal kicker, and study how changing the distance from the goalposts affects how hard it is to accurately kick a field goal.

Safety Never launch projectiles at people, animals, or anything fragile. Be careful not to get your fingers caught in moving parts of the catapult.
Project Idea
thumbnail 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
