Final design of the Assisted Pill Dispenser and APD prototype without final wiring

User has a C4-C5 spinal fracture, resulting in very limited mobility from the shoulders down. Current pill dispensers on the market do not meet user’s needs, since they either require fine motor skills to operate or are out of the user’s price range. The Assisted Pill Dispenser (APD) allows the user to dispense up to seven doses of six different types of pills via independently rotating wheels and a funneling system. The device is completely wireless, capable of receiving and interpreting X-10 signals with its Arduino microprocessor, allowing the user to select which type of pill he/she would like. The user makes a pill selection by using a mouth controlled “sip ‘n’ puff” switch. The only other pill dispenser for a user with tetraplegia costs $10,000 USD to make, and the material list for APD totaled a mere $210 USD.


Solution

To design a reliable, easy to use, and cost effective device to fit our users needs, and the needs of countless others affected by tetraplegia. It utilizes a combination of electrical and mechanical options. Our device meets our user’s needs by working with activation from the sip ‘n’ puff switch currently in place in our user’s home.
