Ninth Grade Robotics Science Projects (2 results)

Robots are made to go and do what humans either can not, or do not want to do. They are used in hundreds of ways from exploring Mars, to working tirelessly on a manufacturing line, to providing companionship. Not to mention they make great movie characters! Try your hand at building a robot with one of our robotics science and engineering projects.

Science Fair Project Idea
How easy is it for you to walk along and follow a line that is painted on the ground? Simple, right? You might be able to follow a line without giving it much thought, but how could a robot do that? In this project, you will build your own automatic line-following robot that can race around a track that you create. This technology has plenty of real-world applications—maybe one day you could help design self-driving cars! Read more

Science Fair Project Idea
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 cannot rely on sight. Did you know that you can also build a robot that uses "whiskers" to find its way around? This 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
