Mar 1, 2026March 2026 RMCS monthly summary: Completed Librmcs v3 integration for the Alliance-Algorithm RMCS hardware stack, replacing the vendored submodule with a FetchContent-based approach and refactoring hardware plugins/configs for the new transport layer. Core plugins were ported to librmcs::agent::CBoard with standardized naming (Hero -> MecanumHero, TunnelInfantry -> OmniInfantry) and board_serial* identification replacing usb_pid*. Migration validated on OmniInfantry hardware; other platforms migrated in-progress with placeholder board_serial* values until testing completes. Ported and reimplemented local helpers (BMI088, DR16, DJI and LK motors, supercap, endian handling, CAN packets, and ring buffers) to the librmcs v3 transport. Updated bring-up workflows and configuration to align with the new architecture. Documented breaking changes to plugin names and parameters and prepared cross-platform validation plan for additional platforms.

May 1, 2025May 2025 Monthly Summary for Alliance-Algorithm/RMCS. Focused on delivering robust autonomy features and improving control fidelity to support safer and more reliable operation in mixed-network and real-world environments. Key features delivered: mDNS dual-stack service discovery enhancements in the set-remote script to correctly issue A/AAAA queries over IPv4/IPv6 multicast, boosting service discovery robustness when both address families are present. Advanced steering and yaw control overhaul introducing a force-controlled steering chassis, analytical quadratic programming solver, DualYawController, reworked input/config handling, and a refactored video transmission controller; integrated a low-pass filter and aligned velocity calculations to an inertial/world frame with IMU yaw data for improved directional control. Minor UI improvements were implemented to support operators. Major bugs fixed: None reported this month; focus on feature delivery and stability improvements. Overall impact: enhanced autonomous navigation reliability and steering precision, enabling safer, more efficient operations across varied networks and environments. Technologies and skills demonstrated: mDNS dual-stack networking, IPv4/IPv6 multicast, advanced control systems (QP solver, DualYawController), sensor fusion (IMU yaw), coordinate frame alignment, software refactoring, and UI improvements.

Dec 1, 2024December 2024 RMCS monthly summary focusing on key achievements and business impact. Delivered a force-based chassis control overhaul using convex optimization, centralizing angular velocity control in the chassis_controller, and replacing the legacy power controller with a vector-friendly matrix_pid_controller. Improved configuration clarity by renaming supercap control to charge_power_limit and tightening access levels in PidCalculator; introduced make_and_bind_directly in InputInterface and made several component inputs optional to enhance robustness and integration. Launched foundational hero robot platform capabilities, including chassis, gimbal, shooting, and UI/status reporting. Expanded ShootingController to support multiple friction wheels, large bullets, flexible feeders, and configurable eject behavior for jam scenarios. Strengthened core architecture with referee and library integrations: merged rmcs_referee into rmcs_core, integrated librmcs as a submodule with wrapper interfaces, and removed redundant serial submodule to reduce maintenance overhead. Enhanced sensor integration and hardware robustness: standardized IMU orientation, clarified hardware transforms (e.g., PitchLink to ImuLink identity) and improved transmit buffer safety and destructor behavior. Boosted repository hygiene and maintainability: updated gitignore rules, removed environment-specific files, and added default configuration guidance. Overall impact: improved system robustness, modularity, and scalability; clearer interfaces and safer hardware interactions enable faster iteration, safer deployments, and stronger platform readiness for upcoming features and production use.
