sl.no Question such as Answers Establish whether it is objectives\constrains\functions
1 What are the features excepted automatic Constrains
2 Should the robot be movable or stationary? Stationary Constraints
3 Maximum weight the robot can lift? 200-250 grams Objectives
4 What is the source of energy? Adapter Objectives
5 Range of operation Up-to 2.5 meters Constraints
6 Weight of the robot 1 - 1.25 kg Constraints
7 Cost estimation of robot 5000/- Constraints
8 Working hours of robot Minimum of 1 hour Function
9 What type of objects should the robot lift Based on height of the object Objective

1.1 Identify Client's Objectives

SL.NO Client's Objectives
1 Cost effective
2 User friendly
3 Safety

1.2 Prioritize identified design objective

Priority among various objectives is set through a technique called Pair-wise Comparison chart (PCC)

Objectives Cost Effective User friendly Safety Score
Cost Effective 1 *** 0 1
User friendly 1 1 *** 2
Safety *** 0 0 0

Rank The objective in the order of decreasing value of the importance and the list is

  1. User friendly

  2. Cost effecctive

  3. Safety

Based on the information gathered through interaction with client, initial survey and completing phase 1.1 the problem definition is formulated as follows

Problem definition version1.1 Design a pick and place robot for cargo ware house industry which should be easily operable, with weight exceeding not more than 2kgs. It should be user friendly, should safely and properly place the objects, The robot must move with adapter as a source of energy |---------------|-------------------------------------------------------------------|

1.3 Identify constraints

  1. robot should be operated automatic

2.cost of the machine should not exceed Rs.5000/-

3.range of operation should be between 2-5 metres

Problem definition version1.2 Design a pick and place robot for cargo ware house industry which should be easily operable, with weight exceeding not more than 2kgs. It should be user friendly, should safely and properly place the objects, The robot must move with adapter as a source of energy, which should be operated automatic, the cost should not exceed Rs. 5000/, the range of operation should be between 2-5 metres |-------------------------------------------------------------|---------------------|

1.4 Establish functions

1.it should sense the shape of the object type

2.it should work more than 1 hour

3.indication after completion of placing it the respective place

Problem definition version1.3 Design a pick and place robot for cargo ware house industrialists which should be easily operable, with weight exceeding not more than 2kgs. It should be user friendly, should safely and properly place the objects, the robot must move with adapter as a source of energy which should be automatic, the cost should not exceed Rs. 5000, it should sense the height of the object type through sensors and place in their respective bin |-------------------|---------------------------------------------------------------|
