Design a semiautomatic nuts sorter which is portable, user friendly, should work on adopter should not exceed the volume of 1ft x 1ft x1ft , should work atleast 4 hrs continuously , should not cross 4000 rupees and should weigh between 2.5kg to 3kg.
3.4 Establish Functions
| Sl.No | Functions |
| 1. | Sort nuts based on different sizes |
| 2. | Should sense the obstacle by IR sensor |
Problem definition version 3.3:-
Design a portable Nut sorter machine which can separate nuts of different sizes ,it should have a power button to switch on the machine and it’s speed should be controlled by human being. Machine should be designed in such a way that it’s dimensions should not exceed 1×1×1 feet and it’s weight should be approximately 2500 grams. The cost should not exceed 4000 rupees. It should work based on IR sensor in such a way that, machine should stop working when the IR sensor detects an obstacle and should work again when the obstacle is removed.
