Ninth Grade, Robotics Science Projects (34 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!

Bristlebot Shape and Motion Tracking
Science Fair Project Idea
Scientific Method
Bristlebots are tiny little robots with no "brain." They are powered by vibrations and move around randomly. Even if there is no brain, can you still influence how they move by changing their design? Find out in this fun robotics project! Read more
Build a Color-Detecting Rover
Science Fair Project Idea
Engineering Design Process
The Mars Curiosity and Perseverance rovers use scientific instruments, nicknamed ChemCam (Figure 1) and SuperCam respectively, to help them analyze the composition of rocks and soil on Mars. You can learn more about these cameras from the resources in the Bibliography, and more about why scientists want to analyze rocks on Mars from the video on this page. Figure 1. The two main parts of the ChemCam instrument on the Mars Curiosity rover.  For a science… Read more
Build a Fuzzy Companion Robot
Science Fair Project Idea
Engineering Design Process
Snuggling a dog or cat can make you feel better even when you are not lonely or sick. Therapy and companion animals are also used for patients in health care settings, but sometimes you cannot always have access to a real live animal. Can a robot serve the same purpose? Find out in this project when you add an Arduino to a stuffed animal to build a purring companion robot. Read more
Build a Miniature Self-Driving Car
Science Fair Project Idea
Engineering Design Process
How do self-driving cars stay on the road? How do vehicles with autonomous or driver-assist features automatically brake, steer around obstacles, or perform tasks like adaptive cruise control? Experiment with these behaviors and more in this science project as you build and program your own autonomous Arduino robot. Read more
Build a Model Planetary Lander with Arduino
Science Fair Project Idea
Engineering Design Process
Imagine that you need to make sure valuable cargo — like a robot or even human astronauts — can land safely on Mars. How would you do it? In this project, you will build your own model planetary lander using an Arduino. It will use a distance sensor and automatically deploy landing gear before impact. Can you avoid a crash landing? Read more
Build a Radio-Controlled (RC) Robot
Science Fair Project Idea
Engineering Design Process
Radio-controlled (RC) robots can explore places that are difficult or dangerous for humans to get to, like collapsed buildings after a natural disaster. They can use cameras and a variety of other sensors to gather information about their environment, like the presence of toxic gases or other hazardous materials. The robots can even use grippers and robotic arms to collect and safely dispose of some materials. You can build your own RC robot using the Science Buddies Bluebot kit, Electronics… Read more
Build a Remotely Operated Vehicle (ROV) for Underwater Exploration
Science Fair Project Idea
Engineering Design Process
Have you ever wanted to explore cold or murky water? What about places where it could be dangerous or difficult for humans to swim? Remotely operated vehicles (ROVs) allow humans to take pictures, videos, and scientific samples of underwater life and habitats while safely operating the vehicle from a boat or from shore. In this project you will design and build your own small ROV that you can test in a bathtub, pool, or nearby body of water. Read more
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 Solar-Tracking Robot
Science Fair Project Idea
Scientific Method
Light sensors are part of many devices that we use every day. For example, they help your phone know when to automatically brighten or dim the screen based on ambient light levels. They can also be used to help solar panels track the sun, which helps the panels generate more power. Many spacecraft and planetary rovers are solar-powered. In this project you will build and program your own solar-tracking robot. Optionally, you can add solar panels and rechargeable batteries. Can your robot keep… Read more
Build a Sound-Tracking Search and Rescue Robot
Science Fair Project Idea
Engineering Design Process
HELP! Locating survivors trapped under rubble is a difficult and dangerous task. After a natural disaster, like an earthquake, rescuers must act quickly to save as many lives as possible. They can use robots with different types of sensors to help find survivors. In this project you will build a sound-tracking robot that can use two microphones to drive toward a sound source. Designing the robot's algorithm will be up to you. Read more
