Elias Cordero developed and maintained the RoboCupJunior-Soccer-Open-League-2025 robotics stack, delivering a robust perception-to-control pipeline for autonomous soccer robots. He engineered real-time ball and goal detection using OpenMV and OpenCV, integrating Python and C++ for embedded systems and microcontroller programming. His work included UART-based data serialization, state-machine-driven control, and repository refactoring to improve maintainability. By implementing camera calibration, coordinate transformation, and sensor integration, Elias enabled reliable navigation and autonomous decision-making. The repository reflects disciplined version control and modular design, resulting in a reusable, competition-ready robotics platform that balances technical depth with practical maintainability for ongoing development.

Jul 1, 2025During July 2025, delivered an end-to-end ball-tracking and UART data pipeline between OpenMV and the robot controller, enabling autonomous ball handling for RoboCup Junior Open League. Implemented and hardened the data packet format, including scaling/packing and reliability fixes, and added a Teensy-side UART receiver with OpenMV data decoding for coordinates, angle and direction, plus an extra 'sentido' value. Established directory-based organization for UART data printing and iterated on the module naming (gemini) to improve maintainability. The work reduces sensor-to-actuator latency and data corruption risk, providing a robust foundation for autonomous control and future features. Key accomplishments were achieved through a focused feature set and disciplined version control, reflected in iterative commits across the data-pipeline components.

May 1, 2025In May 2025, delivered targeted enhancements to the RoboCup Junior Open League project: orange ball detection, angle calculation, and direction mapping improvements, with telemetry exposure for debugging. The X-coordinate is now mapped to a 0-100 range, and angle/direction reporting was refined to support control needs and easier troubleshooting. These changes stabilized perception, improved control reliability, and reduced tuning time, directly contributing to higher match readiness and maintainability. The work consolidated updates to the detection pipeline and control reporting in IITA-Proyectos/RoboCupJunior-Soccer-Open-League-2025, with four commits focused on the relevant script (nombre bonito.py) to implement the changes.
