Absolute Positioning System


This document provides an introduction to and overview of the position tracking and odometry system developed by Team 5225 over the past few years. The document is targeted at VEX team members, specifically programmers, though we’ve tried to make it understandable to all participants regardless of programming or competition experience; there is no code in this document. Additionally, the applications of any odometry system do, hypothetically, extend beyond the VEX Robotics Competition.
