This Arduino-based robot was designed to detect and avoid obstacles using ultrasonic sensors and real-time motor control logic. It autonomously navigated environments by scanning in multiple directions and rerouting on collision detection.
This project was presented at the TDK Science Day and awarded 2nd place for innovation in embedded systems.
Components Used:
Arduino Uno, HC-SR04 ultrasonic sensors
Servo motors + motor driver (L298N)
C++ logic for signal processing and path planning
Prototyping platform (breadboard, jumper wires, 9V battery)
