Objective	score allocated	Justification for the Score
Safety	0	both datum and design 1 provides the same safety
Ease of use	0	both datum and design 1 both are easy for the user to use
Aesthetic	1	design 1 has more balanced shape than the datum
component space	0	almost same components are used in the datum and the design 1
Cost	-1	design 1 is more expensive than the datum because of the use of servo motor
Safety	0	both datum and design 2 provides the same safety
Ease of use	0	both are easy to use
Aesthetic	0	both has same aesthetics
component space	1	less dc motors are used as compared to the datum
Cost	0	both almost cost the same

	Interaction Details(subsystem-1)
	rotation of the cyclindrical body by 360(degree)
	cyclindricl body rotates with arms and domb simultaneously
	moves forward and backward with opposes obstacles
	Interaction Details(subsystem-2)
	domb(head) rotates in 180(degree)
	arms of the bot moves up and down simultaneously
	both domb and arms perform motion simultaneously
	Interaction Details(subsystem-3)
	when human motion is felt then LED starts to blink
	ultrasonic sensors senses the human motion and and rotates the body
	LED light is displayed on the domb when the human motion is felt
