I've been looking into different methods to get my toy's respiratory system working, and it looks like i can create it without using an aquarium pump. I've found a few different diaphram pumps that are small, low voltage, relative inexpensive, and claim to be quiet. I'm also looking into harvesting peristaltic pumps from basic inkjet printers, but am unsure about the pressure they can generate. My back up plan would be to develop a small bellows system that contracts and expands via a gear motor.
The following is a proposed inner diagram of how the piece would connect.
Role: Arnold is a 7 year old child. He is bright and eager to learn. He enjoys spending quality time with his friends and is facinated with science and prates. Moreover he enjoys using his imagination to create fun and novel role playing scenarios using his gi joe and pirate toys. Dr. Bones would cater to Arnold's growing urge to learn by teachign him the basics of human skeletal anatomy. Dr. Bones can be a shared experience as both Arnold and afriend can work towards putting him togeter and Rendering him alive ( shown through a beating heart) and ergo play doctor. Finally once the pice has been built up it can be dissassembled and the pieces can be used individually to cater to his imaginative role playing scenarios. For example a leg bone can now become a dinasour fossil. The toy therefore not only acts as a factual tool but a tool for imagina
Smuggles is a furry friend that latches onto you with his velcro arms. While he's attatched, Smuggles breathing patterns can be felt by the user. You can also squeeze his paws to make him talk.
Amanda is a 9 year old girl who's troubled by riding in the car. She usually is comforted by one of her parents or siblings, but when it's just she and her mom riding in the car, she'll get scared. Smuggles can help calm her down during those lonely rides.
Erin is a 24 year old female currently attending grad school. With her busy schedule, she rarely has time for intimate encounters with others. Using smuggles allows her to have a lifelike friend to cuddle with when she needs some company.
