Feb 1, 2026February 2026 monthly summary for bit-bots_main. Delivered the Whistle Detection and Response System feature, enabling whistle detection in gameplay and robot response. Implemented a ROS-based whistle detection package and node, with a decision element to assess ball visibility based on whistle signals. Prototypes and packages were added with two commits: b77d8be2cae58e4a83c372ad42a628c474119934 (prototype dataflow of whistle detection, co-authored by EnigmaBellatrix) and d349153f96092faeddf0edf6fe01eaf776e20539 (add whistle detector package). No major bugs fixed this month; focus was on feature delivery and architecture groundwork. Overall impact includes improved game responsiveness, human-robot interaction, and a foundation for robust whistle-driven decisions. Technologies/skills demonstrated include ROS, ROS package/node development, dataflow design, integration with gameplay decision logic, and Git collaboration.

Dec 1, 2024December 2024: Bitbots Main delivered targeted odometry refinements that improve localization accuracy and navigation reliability in dynamic environments. Two changes were implemented: yaw drift correction in the step-to-step odometry loop and a pose-estimation enhancement using yaw scaling and IMU fusion. Together, these updates reduce pose drift, stabilize localization, and establish a solid foundation for future IMU-based transforms. This work enhances task success rates, reduces recalibration needs, and demonstrates strong engineering discipline across frame transforms, sensor fusion, and incremental delivery.
