The Classic: Build a Line-Following Robot
Lay painter’s tape on the floor with gentle curves, intersections, and a finish flag. Students sketch route maps, predict tricky segments, and vote on obstacles, turning engineering practice into a collaborative adventure with shared ownership.
The Classic: Build a Line-Following Robot
Show how sensors read reflectivity: dark tape versus bright floor. Calibrate thresholds with classroom lamps and windows, then let teams adjust values. They witness data become decisions, a powerful moment linking measurement to behavior.
