Monthly summary for 2025-08: Delivered multi-repo hardware and firmware enhancements across Arm, Chassis, and RoverFlake2, focusing on wiring optimization, PTZ control improvements, and expanded sensing capabilities. Key outcomes include driver holder redesigns and motor mounting across Link 1 for variant alignment; end effector wiring and mounting geometry improvements; chassis peripheral integration groundwork with new components (PTZ assembly, tube, lidar mounting, placeholder wheels); and a new Arduino PTZ sketch with gas sensor and serial interface. PTZ control refinements improved responsiveness and precision by transitioning to digital pan control and tightening tilt constraints. Note: URDF modeling was attempted in Chassis but not yet successful. Business value includes improved hardware integration reliability, easier wiring management, richer sensing capabilities, and more responsive autonomous control for testing and deployment. Technologies demonstrated include SolidWorks CAD, mechanical/wiring integration, Arduino firmware development, serial communications, and real-time PTZ control.

July 2025 focused on mechanical redesign and system integration for UBC-Snowbots/Arm to improve performance, manufacturability, and readiness for future automation. Delivered three core tracks: (1) Robotic Arm Mechanical Redesign and Enhanced Mounting Alignment, addressing motor hole sizing (A3), bolt circle orientation, bearing covers, spacers, tensioners, and assembly constraints; (2) Slip Ring Integration and Wiring-Hardware Mounting, introducing STEP files for a 12-circuit 5A slip ring and a new SmallHolderHex mounting hardware with alignment mates for A4 wiring management; (3) Deficiency List Tracking and Arm Design Adjustments, establishing a traceable deficiency workbook and updates to A4 dimensions and related components. Key CAD changes and documentation support improved manufacturability and traceability.

June 2025 — UBC-Snowbots/Arm: Focused on strengthening the A1 robotic arm's mechanical interfaces to improve assembly reliability and cross-system compatibility. Delivered an updated mounting interface that standardizes the plate mounting holes and aligns critical components with the chassis, enabling smoother integration with the A1 attachment plate and reducing rework during assembly and maintenance.

May 2025 – UBC-Snowbots/Arm: Delivered foundational URDF capabilities and CAD-to-URDF workflow. Key achievements include partial URDF generation covering coordinate frames, link/joint structures, inertial properties, visuals, and collisions; creation of main Arm URDF defining the full four-axis kinematic chain with configuration files; and an end-to-end workflow to export SolidWorks CAD components to STL. Major bugs fixed: none reported this month. Business value: enables reliable simulation, accelerates integration with planning/control modules, and establishes a reusable CAD-to-URDF pipeline for future iterations.

Monthly work summary for 2025-03 covering hardware and tooling work across UBC-Snowbots Arm and Chassis repos. Focused on delivering measurable improvements in arm reach/pose accuracy, RealSense integration readiness, and prototyping infrastructure, while stabilizing the build process and laying the groundwork for scalable hardware assets.

February 2025 (2025-02): Delivered the Arm system Rev A 2025 mechanical refresh and geometry tuning, achieving increased modularity, better spec alignment, and improved maintainability. Key deliverables include consolidation of the assembly structure, L1 integration, expanded subassembly connections (Wrist under Link 2), new sprockets and Arm Plate, and binary asset updates for Rev A 2025. Geometry tuning refined arm dimensions (L1 spacing, uprights and belt-length) to meet 2025 design specs, enabling more accurate motion and easier future iterations. No critical defects were reported; in addition, housekeeping and repository hygiene efforts (file reorganization and backup cleanup) reduced risk and simplified future work. This work enhances reliability of the autonomous arm, reduces integration risk, and positions the team for faster feature delivery going forward. Technologies demonstrated include mechanical CAD and assembly planning, 3D modeling exports (SLDPRT), version-control discipline, and cross-functional collaboration with design leads.

January 2025 – UBC-Snowbots/Arm: Focused on improving repository maintainability and onboarding by reorganizing the project structure to create a clearer and more scalable layout for assembly assets. Implemented targeted reorganization of assemblies assets and directories, setting the stage for faster feature delivery and easier maintenance.

December 2024 monthly summary for UBC-Snowbots/Arm focusing on asset delivery to support accurate modeling and component placement. Delivered a Moteus r4.11 STEP Asset to the Multi Use Assets directory, enabling precise placement of the Moteus controller board in system models and improving downstream simulation and integration workflows. No major bugs reported in this period. All changes are committed and traceable.

November 2024 — Arm: Timing Belt Sprocket design and drawings delivered, enabling precise modeling and manufacturing readiness. Implemented sprocket geometry and placements; updated engineering drawings and 3D models to align sprockets with the L2 + Wrist assembly, improving visualization and assembly accuracy. Commit activity recorded: 76c6060ecfe37851f8d3848dc66e3978eb1a7bcb (Added Timing Belt Sprockets) and 4b0e5a6d96ee82473a66caaf614157247141c7d9 (Aligned Sprockets + Made Drawing). No major bugs fixed this month; primary focus on feature development and documentation. Technologies demonstrated include CAD design, 3D modeling, engineering drawings, and version control; results support faster downstream manufacturing and reduced rework risk.
