Build a robot that follows a black line on the floor

Steps

1. Choose a ready line-follower kit OR assemble chassis + IR array + motor driver + MCU.
2. Calibrate sensors on black tape vs floor under stable lighting.
3. Wire motors through a driver — never drive gear motors from MCU pins alone.
4. Start with a simple PID or threshold loop; tune speed before adding obstacles.

Start from project kits matching “line follower”, then fill gaps from parts.

Safety

• Use a suitable battery and polarity protection; LiPo packs need correct chargers.
• Confirm motor stall current vs driver rating before full-speed runs.

Assumptions

• Educational guidance only — verify datasheets and your kit’s manual.
• We do not claim this exact build was lab-tested on every SKU in the catalog.
