In April 2025, MissouriMRDT/Autonomy_Software delivered key enhancements to marker-based navigation and ArUco detection, driving safer autonomous operation and improved detection accuracy. The team implemented robust navigation changes to operate effectively in marker-rich environments, including disabling GNSS fusion for group navigation, increasing motor power for reliable motion, and enforcing positional tracking across all cameras. A stop-and-return behavior was added when a marker isn't detected, reducing risk of drift. The ArUco tag detector TorchScript model path was updated to a newer version, improving detection accuracy and inference stability. Visual noise from the detector overlay was reduced by suppressing the tag detector frame display. These changes were validated through targeted testing, aligning with performance and reliability goals for mission-critical autonomy.
