This Arduino project focuses on creating an obstacle avoidance robot that employs ultrasonic sensors for distance measurement and AFMotor modules to control its motors.
The robot detects obstacles in its path and navigates around them.
- Arduino board (e.g., Arduino Uno)
- Ultrasonic obstacle sensor (e.g., HC-SR04)
- Motor chassis with four motors (two for driving and two for steering)
- Motor driver (AFMotor library)
- Battery or power source
- The robot uses an ultrasonic sensor to measure distances to obstacles in front of it.
- If an obstacle is detected at a distance less than or equal to distanceBack, the robot will start moving backward and scanning for an escape route.
- The servo motor is used to sweep the obstacle sensor left and right to identify the safest direction for avoiding the obstacle.
- The robot will move in the chosen direction to circumvent the obstacle.
- If no obstacles are detected, the robot will continue moving forward.
