5.1 JUSTIFICATIONS FOR SCORES GIVEN

Design.no	Objective	Score Allocated	Justification for score
1	Appearance	-2	The appearance of the bot is not as realistic as the datum
	Portable	6	As the shape of bot is simple it is more portable than the datum
	Compact	14	As the shape of the bot is square it is more compact than datum
	Easy to use	0	The mechanism used in the datum is of same ease as that used in this bot
2	Appearance	0	Datum
	Portable	0	Datum
	Compact	0	Datum
	Easy to use	0	Datum
3	Appearance	2	The upper part of the bot is same as datum and with huge wheels at the bottom.
	Portable	-6	As the shape of bot is simple it is more portable than the datum
	Compact	-7	As compared to datum it consumes more area and is more height
	Easy to use	-5	Use of laptop to operate is quite difficult than the handy operator
4	Appearance	2	The appearance of bot is more like a sports car.
	Portable	-4	As it has the blade fixed to its front, it is very difficult to pack it for transportation.
