Autonomous line-following robots
Students build and program a robot that follows a track using reflectance sensors — from wiring to a working autonomous run.
What's covered
- Wiring reflectance sensors and a motor driver
- Reading sensor input and controlling motors in code
- Tuning a simple control loop so the robot tracks the line
- Testing, troubleshooting and iterating on the design
Overview
A proven, classroom-ready robotics unit. Students go from a bare chassis to an autonomous robot that follows a track — learning sensing, control and iteration along the way. Every lesson has been run with real classes before it reached you.
What students build
A working line-following robot they program, test and tune themselves — plus a short design log documenting their troubleshooting.
