Overview
Overview
The goal of this project is to create a pneumatically controlled robotic toy contained within a Shore Buddies stuffed animal. It includes an educational curriculum that encourages the development of logical intuition of basic engineering concepts in children within the age range of 8-12 years old.

Why Air-Powered Robotics?
Why Air-Powered Robotics?
Soft robotics exhibits different properties that can be difficult to achieve with conventional methods, and allow for more fluidic motions. Air powered circuits also give a visual representation of logic circuits that can be seen and felt.

Teaches and shows children how the turtle generates motion
Use to understand a switch (Logic: True/False) in computer and electrical engineering in the form of Truth Table

We set key goals to achieve in our project to fulfill our sponsor's requests:
Robot turtle needs to be able to achieve locomotion by the activation of a pneumatic actuator
Develop an educational curriculum associated with the toy
Conduct at least 5 interviews with potential customers to validate the market needs
Our Design
Our design consists of three main systems: (1) a pneumatic circuit, (2) a walking mechanism,, (3) and an educational curriculum.The pneumatic circuit is centered around a McKibben Pneumatic Air Muscle, and is powered by a 12V air pump controlled by a manual valve.The walking mechanism consists of a scissor mechanism that converts the linear contraction by the McKibben into a sweeping arm propulsion, housed in our "unicorn" shell design to accommodate the McKibben.Lastly, an education curriculum was designed utilizing the air circuit to encourage the development of logical intuition thinking, and market research was conducted to validate the market need.

The robot is driven by a McKibben Pneumatic Air Muscle, with the airflow powered by a 12V pump controlled by a manual valve.
The scissor mechanism housed in the unicorn shell converts the McKibben contraction into walking motion.
