INTRO – PROJECT DESCRIPTION

o Produce a robust prototype that dispenses medication on a time-bases to patients in a secure and accountable environment.

o Allow to dispense a week’s supply of up to 6 different pills for two patients accessed twice daily.

o Reliable and compact electro-mechanical dispensing system that can be controlled by a common laptop.
