JUSTIFICATION FOR THE GIVEN SCORE:

SL NO.	OBJECTIVES	WEIGHTS	DESIGN 1	DESIGN 2	DESIGN 3	DESIGN 4
1.	COST EFFECTIVE	6	It has very simple mechanisms. So, it is cheap.	Mechanisms are not complex. So, it is not expensive.	Datum	Mechanisms are complex and parts are expensive. thus, making it expensive.
2.	IMPACT RESISTANCE	7	which makes it weak.	Mechanisms involved and parts used makes it tough for opponents	Datum	It can take attacks
3.	EFFECTIVENESS OF ITS WEAPONARY	8	Even though it has a full body spinner but they are weak	It has a high rpm motor equipped with wedges which shatter the opponent	Datum	It has a vertical front-facing spinner which attack the opponents as well as throw them away.
4.	USE OF STANDARD PARTS	5	All basic components are used	All basic components are used	Datum	All basic components are used
5.	PORTABILITY	4	It's very lightweight and easy to carry.	It's very lightweight and easy to carry.	Datum	It's very lightweight and easy to carry.
