Autonomous ball grabber robot

The purpose of this project is to achieve a system which is autonomous in nature and also meet the needs and demands of professional sports such as tennis, cricket, baseball or any other sport which involve the use of balls. It is a common notion that when time and money are essence of any activity then professionals do not generally prefer to pick up hundreds of balls after a long day of practise. As a result, our solution is a ball-picker device that is easy to use and cost effective. This device is used for picking up one ball at a time. This device is tailor made to be used for different sporting events other than tennis or baseball which involve balls of similar size and weight. We have used ATMEGA32 microcontroller, L293D dual motor driver board and IR LEDs and photodiodes to achieve our objective. The objective is to use infrared rays as a means to drive the robot as well as avoid obstacles on its path. By suitable arrangement of the pair of IR LEDs and photodiodes the entire system can be realized.
