A)Functions

Sl.no	Functions from User Perspective	Functions from Designer Perspective
1	Sterilize the petri-plate	Sense the petri-plate
2	Fill the media automatically	Hold the petri-plates in a pattern
3	Maintain the biomedical condition	Wash the petri-plates using the chemicals and sterilize them
4		Separate the useful and useless petri-plates for loading the media
5		Move the useful petri-plates for loading the media
6		Load media into the sterilized petri-plates
7		Stop loading after filling media into petri-plates
8		Pass loaded petri-plates using conveyer belts for packing

Summary of Design Concepts

Design Concepts 1 and 2 are the highly space consuming machines. Design 1 works on the principle of biomedical condition for the sterile maintenance of the media. Both design 1 and 2 are on the conveyer and roller belts and DC motor has been used for the easy conveying of loading process. Whereas, for Design 3 and 4 are on the peristaltic pumps are used for loading mechanism. Design 3 and 4 are useful in mass loading of the media into petri plates.
