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.
