PROFILE
Clemens Wulff
Worked on the bit-bots_main repository to deliver robust robotics features focused on game-state management, behavior differentiation, and safety. Developed Python-based state machines and behavior trees to enhance decision-making for gameplay, including dynamic goalie and defender roles, set-piece handling, and whistle-based transitions. Improved robot safety by updating URDF joint limits and refining penalization state tracking, ensuring reliable localization and control. Integrated ROS communication protocols and backend logic to support external control and manual overrides, while addressing bugs related to stability and team handling. Demonstrated strong version control practices and clear commit traceability, resulting in maintainable, reliable, and responsive robotic behaviors.

Mar 1, 2026Month: 2026-03 Overview: This month concentrated on strengthening game-state reliability, enabling external control, and refining in-game decision-making to improve automation safety and gameplay performance. Deliveries span robust game-state management, stability improvements during stopped states, enhanced set-piece decision-making, and sharper whistle-based game-flow transitions. Key features delivered: - Game State Management and External Control: Standby state support, new status and ball state publishing, integration of external stop signals for manual control, and updated game-state messaging. (Commits: ebea481d366d01e2ee453e4bf692e8226ca8ef61; 7e58a0d307c07918220dcf942491bcfb81c845ab; 397f833a69ecc5ce83d5be5ae03a5f7ab8d8b7c6; 7120046e4966892107b684237086ac66044dfba7) - Robot Stability in Stopped State: Fixed stability issues when entering stopped state, added animation-based stability, and improved state transitions to prevent falls. (Commits: a247bd7f952d8dbf41cd5fa6450222c836c33213; 11b4a5f8da2f6ff045ae0bd4ab063faea996fef2) - Set-Piece Decision-Making Improvements: Refined decision-making for corners, throw-ins, and rival free kicks to improve positioning and actions during gameplay. (Commits: 7ea9d6e2ae19fc6557e563c095b1c37aa87055ae; 4ff3bd9c394c43d5d10e85517708b4ab8972d4c1) - Whistle Detection and Game Flow Enhancement: Enhanced whistle detection to localize during state transitions and ensure correct game-state updates in response to whistle signals. (Commit: 84ebddd998eb9297b53355879fce94dde530993e) Major bugs fixed: - Robot Stability in Stopped State: Addressed instability and fall risk when transitioning to/staying in stopped state; updated transitions across HCM and body behavior modules to prevent falls. (Commits: a247bd7f952d8dbf41cd5fa6450222c836c33213; 11b4a5f8da2f6ff045ae0bd4ab063faea996fef2) Overall impact and accomplishments: - Increased reliability of game-state handling and external control, enabling safer manual interventions and clearer game-state signaling to downstream systems. - Reduced risk of robot falls during stop/start transitions, improving uptime and safety in real-game scenarios. - Improved in-game decision-making for set-pieces, leading to better positioning and more consistent scoring opportunities. - Sharper game-flow control through improved whistle localization, reducing mis-synchronization between sensors and gameplay state. Technologies/skills demonstrated: - Real-time game-state management, publish/subscribe patterns, and external control integration. - State-machine design, robust error handling, and safe transition policies. - Computer vision-assisted localization triggers (whistle-based cues) and localization-aware state transitions. - Algorithmic decision-making for football actions (corners, throw-ins, rival free kicks) and behavior-driven development. Business value: - More reliable automated gameplay with safer manual overrides, increasing team performance margins and reducing operational risk during matches and demonstrations.
