March 2025: Expanded monitoring and reliability for Cabot, delivering robust ODrive diagnostics, new system diagnostics configuration, and targeted code quality improvements. Stabilized tests and linting across can_node, reducing false failures and improving maintainability. These efforts provide clearer health signals, faster issue resolution, and safer deployments.

February 2025 monthly review: In the CMU-cabot/cabot-drivers repository, delivered key CAN-centric improvements and strengthened diagnostics to boost observability, reliability, and maintainability for sensor-rich configurations. The work focused on enhancing CAN diagnostics, sensor monitoring, and socket-handling robustness, enabling faster triage and more reliable operation in deployment environments.

January 2025 (2025-01) monthly summary for CMU-cabot/cabot-drivers: Highlights include robust capacitive sensing enhancements, a critical initialization fix, API alignment improvements, and strengthened type safety. Delivered capacitive sensor calibration enhancements with updated CAN IDs, a new noise-nullification service, and recalibration parameters to clarify configuration and improve robustness against negative delta counts and RF noise. Implemented a fix to ensure a CAN frame for capacitive touch calibration is transmitted after enabling the sensor input, addressing initialization timing. Aligned the recalibration API and data types with improved, structured logging by updating message types from Int16 to UInt8 and refining the output format. Resolved a can_frame parameter type specifier bug to prevent runtime errors. Overall, these changes improve reliability, reduce setup time, and enable faster debugging in field deployments.

Month: 2024-12 — CMU-cabot/cabot-drivers delivered targeted CAN bus and sensor improvements with a focus on reliability, performance, and maintainability. Key features delivered include a CAN bus filter overhaul with improved IDs, masks, and routing to strengthen communication reliability, and capacitive touch/sensor enhancements with new CAN IDs/DLCs, recalibration subscriptions, and a calibration service, plus updated documentation. A critical bug fix standardized CAN ID/DLC values and data types for vibrator/power control, strengthening data transmission reliability. These changes reduce runtime errors, improve real-time behavior, and enable richer sensor capabilities for downstream systems.

Month 2024-11 focused on stability, data integrity, and build hygiene for CMU-cabot/cabot-drivers. Addressed a data-loss incident by reverting to a previous stable state, cleaned up the directory structure, and aligned the CAN node build artifacts with a renamed executable cabot_can_node, with corresponding CMakeLists.txt and source updates. These changes reduce risk of future data loss, simplify maintenance, and improve build reliability.
