PROFILE
Alex Sagredo
Alex Sagredo developed and refined mechanical subsystems for the UBC-Snowbots/Chassis repository, focusing on differential and PTZ camera systems over eight months. Leveraging SolidWorks and CAD design, Alex delivered modular 3D models and assemblies for differential prototypes, sensor mounts, and camera integration, emphasizing maintainability and rapid iteration. Their work included topology optimization, simulation groundwork, and manufacturing-ready refinements, such as DXF exports and assembly integration. By reorganizing CAD files and establishing robust version control, Alex improved traceability and onboarding. The engineering depth is reflected in the integration of hardware features, modular chassis enhancements, and expanded camera coverage without reported bug regressions.

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.
