Developing an Autonomous Robot Platform for Robotics Enthusiasts
In the journey to simplify entry into robotics, the autonomous robot platform project aims to offer mobility and communication capabilities. Addressing the limitations of existing hobby and commercial robots, the goal is to create an affordable, user-friendly system that navigates autonomously, communicates wirelessly, and serves as a foundation for diverse projects. The project is focused on achieving various goals across different versions, with the current phase emphasizing reliable wireless communication, obstacle avoidance, environment mapping, user-directed movements, and basic operations. Building on past progress and addressing challenges faced, the project is set to advance through software development, obstacle avoidance refinement, mapping enhancements, navigation improvements, additional hardware integration, wireless communication optimization, dead reckoning features, and base software development.

ECE298 Paul Rayes Hello. I m a robot. AUTONOMOUS ROBOT PLATFORM
Overall Goal Overall Goal to develop a platform that simplifies getting into robotics by supplying mobility and communications
Existing Solutions Hobby robots: 3pi, Ardubot Not autonomous Often do not have communication Commercial robots Cost thousands of dollars Roomba No The ideal solution does not exist Existing Solutions
Overall Goals (partial list) Cost under $500 (ideally under $300) Easy to use Navigates autonomously in an environment Communicates wirelessly Can have many robots working together Can be used as a foundation for other projects Overall Goals (partial list) Divided goals into different versions
Version 1 Goals (partial list) Reliable Wireless communication Detects and avoids obstacles Creates a map of the environment Goes to a point specified by the user Basic base operational Version 1 Goals (partial list)
Last Semester Last Semester First prototype on breadboards Basic obstacle avoidance Too much time spent troubleshooting loose connections
This Semester This Semester
This Semester This Semester
This Semester This Semester Need to write more code to control the new hardware
Block Diagrams (v2) Entire System Robot Charging Station (v2)
Next Steps Write the software Obstacle avoidance Map creation Navigation Additional hardware Wireless Dead reckoning Develop the base software Next Steps
Failures / Lessons Learned Two PCB connectors are 2mm off Two circuit boards had problems in the layout Failures / Lessons Learned Fully check every design before building Schedule twice as much time for everything as you expect you will need Document as you go Put connectors and buttons at accessible places
