This autonomous robot is designed to collect tennis ball on court. It is fully self-contained without human intervention.
Functions:
1) Collect tennis balls with self-made mechanism.
2) Unload tennis balls to pre-defined location.
3) Microcontroller controlled, self-contained.
4) Ultrasonic sensors for obstacle avoidance.
5) Self-built GYRO system for navigation.
6) Wheel-chair configurations for robot movement propelled by two stepper motors.
Parts Used:
1) Cheap aluminium frame
2) 2xStepper motors
3) Used Printer paper loader for ball collecting
4) Motorola M68HC11 microntroller chip.
5) 3xpairs of Ultrasonic Sensors.
6)GYRO - two dc motors to propel two disks(inertia) and mounted on a 360 degree pot.
