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.
