Prioritize the identified design objectives
Priority among the various objectives is set through a technique called as Pair Wise Comparison Chart(PCC)
| Objectives | Safety | Affordable | Collection of different kind of waste | User friendly | score |
|---|---|---|---|---|---|
| Safety | ***** | 1 | 1 | 1 | 3 |
| Affordable | 0 | ***** | 1 | 1 | 2 |
| Collection of different kind of waste | 0 | 0 | ***** | 1 | 1 |
| User friendly | 0 | 0 | 0 | ***** | 0 |
Rank the objectives in order of decreasing value of importance and list is
- Safety
- Affordable
- Collection of different kind of waste
- User friendly
1.1 Identify client's objectives
Step 1: Prepare the list of design objectives
1.Robot should be controlled by wireless ways.
2.Robot should efficiently collect all the waste.
3.Robot should be portable.
4.The robot should have wide tyres to drive through sand.
Problem definition 1.1
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 portable.It should be controlled by an individual and the robot will be controlled by wireless means like Bluetooth .The device should destroy the litter collected.
1.2 Identify constraints
-
It should not exceed Rs.5000.
-
It should work for atleast 3 hours after it is charged.
-
The wireless connection should have a range of 10 meters.
-
The robot should be controlled by an individual.
-
As it is a small robot it can destroy only the materials like plastic bags, cigarettes , plastics cups , papers , small shells. etc.
Problem definition 1.2
The robot should not exceed about 5000 rupees, should work for at least 3 hours and it should be controlled by an individual.The device should destroy the litter collected and wireless connection should have a wide range of 10 meters.
1.3 Identify functions
-
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.
-
Manually remove the garbage.
-
Make a even level surface of sand after collecting the garbage.
Problem definition 1.3
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 and it can be controlled by only one individual and the robot will be 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.
