LoonyOdo is the Loony Squad's open source dead wheel odometry solution. The project was made to create a repository of inspiration, tips, and design requirements to help teams create their own odometry pods. This project was led by Alex with support from Jameson and Jamie on the instructions and rendering sides, respectively.
LoonyOdo comes in six flavors, using three combinations of backplate designs each compatible with two different encoders. The construction is comprised of 3D printed, CNC'd, or COTS parts, and the result is a very compact and robust set of pods. With its simple design and easy serviceability, LoonyOdo is made to be compatible with nearly any robot.
The instructions and design guide for LoonyOdo can be found here: https://docs.google.com/presentation/d/1dEYNUNY_9nqMl-R3nphqr-574irAsfmFc599L6unDIM/edit?usp=sharing. This document contains design theory for creating odometry pods, examples of pods from various teams, the major components of odometry, resources for programming with odometry, and complete assembly instructions for the six official versions of LoonyOdo.
