5.3 Justification for the scores given

sl.no	Design Name	Objective	Score Allocated	Justification for the score
1	Linkage Mechanism	It must be elephant bot	10	To design the elephant bot to join the parts the linkage mechanism is useful
		It must be user friendly	0	Here there is no usage of linkage mechanism
		It must be kinetic bot	8	To movement of our bot there is use of link between two parts. The links are done by linkage mechanism
		It must be attractive	0	In this objective there no use of linkage mechanism
		It must be compact	1	use of small links it can be compact
2	Gear	It must be elephant bot	5	By using gears it will most appealing elephant
		It must be user friendly	-4	For this objective there no use of gears
		It must be kinetic bot	4	for movement of bot there is usage of gear which make it perfect
		It must be attractive	0	No usage of gears
		It must be compact	1	Use of some small and efficient gears can make it a little compact
3	Pin Joint	It must be elephant bot	10	To get perfect design of elephant we will use pin joint
		It must be user friendly	0	For user friendly there is no use of pin Joint
		It must be kinetic bot	8	For movement/kinetic elephant there more use of pin joints foe example in movement of legs the pin joint is used
		It must be attractive	0	For this objective there is use of pin joint
		It must be compact	1	Use of pin joint for joining small parts in compact elephant
4	Rocker Mechanism	It must be elephant bot	10	In elephant bot the rocker mechanism is used for movement of tail
		It must be user friendly	0	Here there is no use of 4-bar gears
		It must be kinetic bot	4	There is a use of 4-bar gears for the movement mechanism
		It must be attractive	0	Here there is no use of 4-bar gears
		It must be compact	0	Here there is no use of 4-bar gears
