A “master” rover is followed by one or more rovers in a line. Based on color signals on the road the master stops or park; the followers read the ranger sensor and keep a safe distance from.
In the activity are used
✓ Distance ultrasonic sensor (Ranger)
✓ Color sensor
✓ Motion commands: FORWARD, STOP, RESUME, TURN LEFT/RIGHT
✓ Rover frame of lightweight wooden body on which a rear barrier is inserted to increase the effectiveness of the distance sensor
✓ 5 m long cardboard track The trajectory control is performed by reading the colors at the edges of the track and an algorithm for correcting the direction of motion.
