Sep 1, 2025

Month 2025-09 — Two high-impact features delivered across rover_micro and rover repos, focusing on camera control reliability and panorama imaging. In rover_micro, CameraInterface refactor and gas sensor messaging initialization support independent handling of PTZ and power commands, improving camera control reliability and sensor data flow. Commit: 1471973b17483ab85779fe2af4421feeabddf513 (IMport (#83)). In rover, panorama capture and stitching were added, introducing ROS nodes/services and client-side logic to capture, stitch, and save panoramas with duration control and a designated save path. Commit: 57fc4df2a84d59f6c5d1c2a93dc0fe1c2a94603b (Panorama (#203)). No major bugs fixed this month; the focus was feature delivery and integration polish. Overall impact: enhanced perception and data capture capabilities, enabling richer mission imagery and streamlined operator workflows. Technologies demonstrated: ROS nodes/services, client-server patterns, message definitions, interface refactoring, and image stitching workflow.

Mar 1, 2025

March 2025 performance summary for robotique-udes/rover. Delivered foundational data structures, CV integration, and substantial threading and recording capabilities with a focus on reliability and performance. Implemented initial hashmap and integration of computer-vision variables, improved threading subsystem (Thread V2), advanced recording workflow (including interval recording, in-recording screenshot handling, and appending recordings). Enhanced FPS tracking and overall performance. Updated dependencies/build system, logging, and code quality. Reintroduced the camera controller module, added GStreamer RTSP streaming and related screenshot capture/cleanup, and performed targeted bug fixes to harden runtime (shutdown synchronization, safe delete, and general stability). Result: more reliable data capture, streaming, and multi-threaded operations enabling faster feature delivery and maintainability.
