Learning track
Build a line-following robot
Six parts from bare chassis to a robot that holds a line at speed — sensors, motor driver, calibration and a control loop that behaves on carpet and tile.
A line follower is the classic first robot because every hard problem in robotics shows up in miniature: noisy sensors, motors that don't match each other, and a control loop that has to run fast enough to matter. This track builds one properly — sensor calibration first, bang-bang control second, then PID once you can see why bang-bang wasn't enough.
