Concept No.	Objective	score	justification
1.	Safety	dattum
	Ease of use	dattum
	Portability	dattum
	Use of standard parts
	cost	dattum
	Attractive	dattum
	Efficiency	dattum
	Less power consumption	dattum
2.	Safety	-9	The parts are not enclosed and it could cause harm to the user
	Ease of use	0	it is the only design that can take a box from anywhere and keep it in the bin but it takes lot of steps to do
	Portability	-12	very less portable than concept 1
	Use of standard parts	7	parts are easily available like hook,joystick,dc motor
	Cost	6	it is less cheaper becauseparts are not complicated and can easily available
	Attractive	5	The tranportable conveyor makes the prototype more attractive
	Efficiency	8	it finishes both the work of picking the box from anywhere and placing it in respective bin
	Less power consumption	7	As it uses dc motor power consumed is less
3.	safety	9	All parts are enclosed in well structured body
	Ease of use	9	it is easily usable as it has vacuum to carry boxes
	Portability	-6	parts are not portable
	Use of standard parts	-7	parts such as vacuum,motor is easily available but digital display is not easily available in the market
	Cost	-6	vacuum and digital display costs more
	Attractive	5	Vacuum and digital display makes the prototype attractive
	Efficiency	16	finishes the work fast by sensing the shapes
	Less power consumption	0	same as concept 1
4.	Safety	18	The robotic arm do the work more safely than the remaining concept designs
	Ease of use	8	As mentioned above the Robotic arm can do the work easily with less manual effort
	Portability	-6	the prototype is not portable
	Use of standard parts	7	Parts like grabber,Robotic arm,partial turn motor are easily available
	Cost	-6	Color sensor and Robotic arm are costly
	Attractive	5	The Robotic arm makes it attractive and color sensing too
	efficiency	16	It finishes the work faster as it has Robotic arm and conveyor
	Less power consumption	-7	The motor consumes more power than the rest 3 prototypes

So,selected design is Conceptual design 4
