Apr 1, 2025April 2025 – ECLAIR-Robotics PCR_Automation: Delivered a robust development ecosystem and end-to-end automation capabilities, focusing on reproducibility, localization accuracy, and cross‑platform integration. Key features included a Docker-based robotic arm development environment with ROS 2 Humble, MoveIt, Gazebo, and tooling; expanded XArm model assets and workspace configurations for collision-safe visualization in ROS; a ROS 2 TCP bridge enabling cross‑platform communication (with a Python sender and Docker Makefile updates); Bird's Eye View enhancements for AprilTag-based localization and visualization; and automated liquid handling using computer vision with precise spatial control and safety checks. Major bug fix highlights include repository hygiene improvements by updating .gitignore and excluding build/install/log artifacts. Overall, these efforts accelerate onboarding, improve simulation-to-real transfer, increase measurement accuracy, and enable end-to-end automation with stronger reliability. Technologies/skills demonstrated include Docker, ROS 2 Humble, MoveIt, Gazebo, rosdep, Python, 3D asset workflows (STL/OBJ), AprilTag localization, cross‑platform IPC, and Git hygiene.

Feb 1, 2025February 2025 performance summary for ECLAIR-Robotics/PCR_Automation. Focused on delivering a modular Computer Vision pipeline and improving repository hygiene to support reliable, scalable development. Key features delivered: - Computer Vision module: integrated circle detection and distance estimation from AprilTag pose, with refactor into birdseyeview.py to create a modular, maintainable architecture. This lays the groundwork for robust perception in automated workflows. - Repository hygiene improvements: updated .gitignore to exclude development files (e.g., .vscode, venv) to prevent accidental commits and reduce noise in CI pipelines. Major bugs fixed: - No critical bugs reported this month. Notable efforts centered on readability and maintainability, including comments in the main function and modularization of the Birdseye view logic to reduce future defect risk. Overall impact and accomplishments: - Strengthened perception capability alongside maintainability, enabling faster feature iteration and safer code management. - Reduced technical debt related to dev-file leakage and brittle repository state, improving onboarding and CI reliability. Technologies/skills demonstrated: - Computer Vision: circle detection, distance estimation via AprilTag. - Python modularization and refactoring (birdseyeview.py). - Code readability enhancements and inline documentation. - Git hygiene and collaboration best practices (co-authored commits).
