Today, the current solution for dogs with disabled or missing legs is to provide either a crutch or wheelchair for the remainder of its life. The goal of this project is to provide a more innovative solution to this issue, giving disabled dogs the chance for a more natural mode of movement.
The K-9 Exo Suit acts as a wearable prosthetic that provides support to the dog’s hind legs, as well as give real time updates to the owner about the patterns and performance exhibited by the subject. It will record these readings and recognize possible corrections for the subject’s exo-assisted movement, using it to improve the product’s performance with continued use.
The CAD files were created in Autodesk Fusion 360. Files are provided under the “CAD” folder.
Used to predict the sequence of movements taken by the prosthetic. It has three binary inputs (motion detected, left front leg in motion, right front leg in motion) and one binary output (activate appropriate servos).
Dynamixel AX-12A servo motors were used as the hip and knee joints of the prosthetic model. The servo motors were programmed using the Dynamixel SDK and Raspberry Pi.
The Web Application is run through phpMyAdmin which is connected by an Apache2 web server. A SQL server database stores the data obtained by the suit and communicates with the web server to display on phpMyAdmin.
