Description

We want to raise the bar in high school robotics. In Texas, and likely in many other states as well, high school robotics has reached a roadblock when it comes to autonomous navigation. In many competitions, the autonomous portion sees few, teams successfully completing tasks that require positioning and guidance. In modern robotics, it is no longer sufficient for a robot merely be “remote controlled.” They need to be able to navigate independently and adapt to the environment around them. To achieve this goal a positioning system is needed to develop the foundational algorithms for autonomous controls. However, these systems are often prohibitively expensive or proprietary, preventing their use at the high school level. To address this challenge, we continued the work done from senior design project to developed a simple, open-source, low-cost positioning system designed for use in high school environments to advance the state of educational robotics.
