Following Was The Information Obtained Through Basic Research And Customer Interaction:

Observation And From lit.Survey	Requirements
1. Based on the weight of other bots and the weight that a student can easily carry	The bot's weight must not exceed 1.5 - 2 kg
2. A student can identify the movements of different animals and insects	The bot is most suitable for students of age group 10-15
3. Based on the cost of competing products in the market	Cost of the bot is around 3000 Rs
4. At the age of 13 the students will be able to recognize different bone mechanisms of animals	The bot must include diversity in the way the bones are arranged for walking
5. Students may not handle the bot delicately	Materials used must be safe and student friendly

1.1 Clients Objectives

Sr no	Objectives
1.	The bot must be affordable (less initial cost, low maintenance
2.	The bot must be user friendly (easy to use, easy to carry)
3.	The bot must not occupy a lot of space
4.	The bot must have a good battery backup (easily chargeable)

1.2 Prioritize The Identified Design Objectives

Priority Among Various Objectives Is Set Through A Technique Called Pair Wise Comparison Chart (PCC)

Objectives	Safety	Cost Efficient	User Friendly	Less Space	Battery Efficiency	Score
Safety	***	1	0	1	1	3
Cost Efficient	0	***	1	1	0	2
User Friendly	1	0	***	0	1	2
Less Space	0	0	1	***	0	1
Battery Efficiency	0	1	0	1	***	2

Based On The Information Gathered Through Interaction With Client, Initial Survey And Completing Phase
