Introduction What are Biological Samples and what is a Biobank? Biomech
Biological Sample -Is a biological specimen including, blood, tissue, urine, etc. -used for a wide range of research applications; such as, genomics, proteomics, tissue banking, glycerol stocks and long-term storage of enzymes and other biological stock solutions Biomech http: //www. af. mil/shared/media/photodb/p hotos/050110 -F-0000 P-005. jpg
Biobank -also known as a biorepository, is a place that collects, stores, processes and distributes biological materials and the data associated with those materials. -these samples are contained usually between the temperatures of -20 C to -80 C under controlled dry air conditions to prevent frost build up - Major concern with present biobanking systems, is the temperature fluctuation and time lapse Biomech http: //www. ccg. uni-koeln. de/img/tec/biobanking.

2. Temperature needs to remain constant at -80 C* Primary Objectives 1. Use Previously Designed Frame* Frame 3. Self Contained System* 1700 mm. X 570 mm. X 790 mm(WXDXH) Biomech
Objective Design an end effector for an automated biological sample storage and retrieval robot. The end effector needs to perform a pick and place operation on biological sample tubes within a -80 C environment. Biomech
-Reliably work in a -80°C environment Design Constraints -Mount to a 50 mm x 50 mm linear bearing platform on the robot -Electrical power is not supplied to the end effectors platform. Biomech
Temperature Must work reliably under -80 degree Celsius environment to keep sample viable. Limited Material selection, Limited mechanical components can be used Metal: Stainless Steel 304 Plastic: Polyetherketone(PEEK) Biomech
Mount to a 50 mm x 50 mm linear bearing platform on the robot Limited Platform Spacing 95 mm 1700 mm. X 570 mm. X 790 mm(WXDXH) Biomech
Tube Spacing 3. 45 mm Biomech
