Problem definition

Design a robot which can collect the wastes like plastic, organic and wet materials on the surface of sand, which should be safe enough to use and it should be portable. The robot should not exceed the cost of 5000 rupees, which can work for at least 3 hours when fully charged, it can be controlled by an individual and the robot is controlled by wireless means like Bluetooth .The device should destroy the litter collected,the wireless connection should have a wide range of 10 meters and it should create an even level surface of sand at the end of cleaning.

1. Black Box representation

INPUT	OUTPUT
1)Electrical Energy	Mechanical work
2)Data	Build wireless connection
3)Garbage	Destroyed and compressed Garbage

2.List of main functions of a system

Build a wireless connection between robot and the controller.
Collection of the litter from the shore of the beach.
Destroy the waste collected in the robot.
Make a even level surface of sand after collecting the garbage.

5)After the garbage collector is filled the machine will indicate the user by blinking an led light.
