INTRO – PROJECT DESCRIPTION o o o Produce a robust prototype that dispenses medication on a time-based schedule to patients in a secure and accountable environment. Allow to dispense a week’s supply of up to 6 different pills for two patients accessed twice daily. Reliable and compact electro-mechanical dispensing system that can be controlled by a common laptop. 3
INTRO – PROJECT DESCRIPTION Laptop communicates information to the dispenser User inputs finger print information Dispenser produces medicine 4
INTRO - SCOPE Start with a working prototype. ~5 years outdated Modify to meet customer needs and specifications. Deliver functioning prototype by end of MSDII. 5
INTRO – Target End User One who takes medication on a regular basis, is technologically capable*, and desires to have their medication in a safe and secure environment. * a technology capable person is familiar with basic computer functions and/or has the willingness to learn. 6
