Dec 1, 2025OpenHUTB/nn — December 2025 Monthly Summary Key deliverables and outcomes focused on reliability, performance, and business value in humanoid navigation simulations. Key features delivered - Humanoid Robot Dynamic Obstacle Avoidance and Advanced Navigation: dynamic obstacle handling (including sliding walls), multi-target navigation, fixed/distance-priority navigation, robust path handling, and cross-platform model loading. Improved control stability to prevent falls; enhanced directory handling for consistent loading across Windows/macOS/Linux. - Distance-priority, multi-target and fixed-point navigation: implemented distance-priority multi-goal decision making and fixed-target navigation in dynamic environments, enabling more predictable and efficient routes. - Mujoco/open-model optimizations and obstacle modeling: integrated open-source Mujoco models, added wall2 sliding obstacle joints, and refined obstacle definitions to better reflect real-world dynamics. Major bugs fixed - Startup path resolution and cross-platform issues: automatic startup working-directory switch, standardized path separators, and robust model-path validation with clearer error messages to prevent missing-file failures. - Model loading and XML parsing: resolved issues around MuJoCo XML parsing and dynamic obstacle modeling (e.g., rand() usage in pos attributes) and improved robustness of model loading across environments. - Simulation initialization and visualization: corrected initial world coordinates and reduced UI flicker, improving stability and debugging visibility. Overall impact and accomplishments - Significantly improved simulation reliability and reproducibility across platforms, accelerating experiment setup and iteration cycles. - Enhanced navigation accuracy and resilience in dynamic scenes, enabling more realistic testing and faster validation of algorithms. - Strengthened engineering discipline around path handling, logging, and encoding (UTF-8), reducing operational friction for teams and downstream deployments. Technologies/skills demonstrated - Python-based path handling, cross-platform I/O, and structured logging with [INFO]/[SUCCESS]/[ERROR]-style prefixes. - Mujoco model integration, dynamic obstacle modeling (including sliding walls), and multi-target navigation strategies. - Distance-priority decision making and fixed-target navigation under dynamic constraints. - Robust debugging practices: automated startup configuration, clear error messaging, and UTF-8 encoding discipline.

Nov 1, 2025November 2025 performance overview for OpenHUTB/nn: Implemented robust humanoid model loading and walking improvements, delivering cross-platform reliability, clearer diagnostics, and stable walking performance. Key work included automatic working-directory resolution, cross-platform path normalization, and model path existence checks in humanoid_motion_control. Addressed root causes of path-related loading failures and initial pose balance, and aligned joint limits and inertia parameters. Repo hygiene updates and environment config enhancements reduce setup friction for new contributors. The work directly improves simulation reliability, reduces debugging time, and enables more consistent progress on humanoid robotics research and development.
