Our team designed and built a line-following robot powered by Arduino for the Pathfinder Competition. I was responsible for programming the robot’s core behavior, allowing it to follow a black line using a color sensor while detecting obstacles with ultrasonic sensing. We implemented logic for path correction, dynamic turning, and real-time decision making to support smooth autonomous navigation. The robot also performed multi-angle scanning to recover when it went off track and intelligently handled blocked paths. Through strong teamwork and an effective design approach, we won first place in the competition and received a $300 prize.
