Abstract

A pill dispensing system includes a tamper resistant top module, an outer case, and a bottom module. The top module includes a locking mechanism configured to lock and unlock the top module. A removable first inner container module includes a pill storage compartment configured to contain a plurality of pills. The removable first inner container module is disposed in a second inner container module positioned in the outer case. The bottom module includes a gate and pill dispensing mechanism. The pill dispensing mechanism is configured to dispense a pill through the gate at a scheduled time configured by a microcontroller. The length of the pill dispensing system is less than twice a diameter of the outer case.
