Highlights
- —Dual IR sensors follow 2cm-wide black line with >90% accuracy
- —Ultrasonic sensor halts robot if object <10cm, resumes when clear
- —Finish line recognition with 4cm-width tape detection (9/10 trial success rate)
- —Touchless start via ultrasonic trigger (hand wave), <250ms reaction time
Results
- —>90% line detection accuracy under indoor lighting
- —Lightweight design (~0.5 lb) with 3D-printed PLA chassis, total cost ~$30.83
