Design 1 is selected as a best idea

Justification chart

Design 1

Objective Score Justification
Dispense the object 20 Dispensing of object is very easy
Agile 9 wheels movement is quicker than roller
Good battery life 8 Complexity of Mechanism is less and feasible due to which Battery lasts long
Stability 14 Very stable as compared to roller

Design 2

Objective Score Justification
Dispense the object 10 Dispensing of the object is easy
Agile -18 Belt drive mechanism is faster than rollers
Good battery life -8 Due to more mechanisms battery life doesn't lasts long
Stability -14 It's not stable as the contact surface is very less

Design 3

Objective Score Justification
Dispense the object 10 Dispensing is easy as compared to design 4
Agile -9 It's not that fast due to it's circular structure which opposes the speed of the wheel
Good battery life -8 Due to many mechanisms battery life doesn't lasts long
Stability -7 It's not stable as compared to datum

Design 4

Design 4 is considered as Datum.
