PROFILE
Krish Kittur
Over six months, contributed to hytech-racing/drivebrain_software by developing and refining features for embedded vehicle control and state estimation. Integrated Simulink-based code generation into the CMake build system, modernized CAN communication logging with spdlog, and enhanced inverter state estimation robustness through improved concurrency and data handling. Delivered power limiting in control logic to prevent motor overloads, expanded CAN database definitions, and ensured reproducible builds using Nix. The work emphasized maintainability and reliability, with careful attention to unit testing, dependency management, and thread safety. Utilized C++, CMake, and Nix to address real-time systems challenges in robotics and vehicle dynamics.

Feb 1, 2025February 2025 monthly summary for hytech-racing/drivebrain_software: Delivered Power Limiting Functionality in SimpleController to cap torque based on current RPM and a defined power limit, preventing overloads in high-demand scenarios. Implemented accompanying unit tests to validate power limiting behavior across high RPM and varied driving scenarios. Changes were committed in two commits (63cc72e6.. and bff92349..), and the repository builds successfully with the new feature and tests in place. Impact: reduces risk of motor overload, improves drivetrain safety, reliability, and predictability of actuation. Technologies/skills demonstrated: embedded control design, C++ control logic, unit testing, build validation, and test-driven development.

Oct 1, 2024Month: 2024-10. This period delivered the integration of Simulink-based code generation into the drivebrain_software build pipeline, establishing an end-to-end codegen workflow and aligning dependencies for reproducible builds. The work includes updating the build system to include code generated by simulink_automation, replacing matlab_math with a codegen package, updating drivebrain_estimation linkage to use codegen::Tire_Model_Codegen, and updating Flake tooling (flake.lock and flake.nix) to reflect new dependencies and package references. No separate bug fixes were reported this month; the primary focus was enabling the code generation pathway and ensuring build reproducibility. The work is documented by commit 736df7d8f33d4130f5febaf929073098925452c7.
