Developed and integrated a travel distance meter feature for the agh-space-systems-rover/kalman_robot repository, focusing on odometry-based distance tracking within the kalman_arc package. Leveraged Python and CMake to implement a node that calculates and publishes the robot’s traveled distance, enabling improved downstream state estimation and navigation. The work included creating the kalman_arc package, integrating supervisor arc.py for extended Kalman-based workflows, and stabilizing packaging and build processes to enhance CI reliability. These contributions improved system observability and readiness for downstream processing, demonstrating practical application of ROS, robotics, and build automation skills in a collaborative development environment.
