Nov 1, 2025For 2025-11, the Chassis team delivered a targeted upgrade to the Pan-Tilt-Zoom (PTZ) system, expanding testing capabilities and refining PTZ components to improve reliability and maintainability. The work included introducing new testing pieces and updates to PTZ assembly, covering inner/outer test components and modifications to existing PTZ parts to enhance functionality and design. These changes, backed by two commits, establish a stronger validation workflow and a more robust PTZ subsystem for field deployments. While no explicit major bugs were reported this month, the improvements reduce risk in integration and future feature work, and lay groundwork for upcoming performance enhancements and automation.
