Engineering work, shown in context.

Challenge

A kiosk application could stop responding during operation, leaving the terminal unavailable until someone intervened. Recovery had to work reliably on restricted Windows machines and remain supportable.

Approach

• Converted failure modes into monitoring, recovery, logging, and rollback requirements.
• Built a one-shot PowerShell monitor launched every minute through Task Scheduler.
• Added anti-flapping, health logs, hidden execution, state tracking, and retention.
• Validated the package in UAT before rollout support.

Contribution

• PowerShell health checks and restart logic
• Task Scheduler and VBScript deployment
• UAT, documentation, rollback planning, and knowledge transfer

Outcome

• Reduced reliance on manual observation.
• Created a repeatable engineering support package.
• Progressed from UAT to operational rollout at multiple outlets.

Challenge

The system needed to move roll cages between levels through constrained lanes, ramps, roads, traffic interactions, and output-chute operations without modifying the cages.

Approach

• Mapped the current flow and collected site measurements.
• Compared indoor staging and outdoor-road concepts.
• Defined requirements for under-riding, towing, and forklift-style robots.
• Used concept drawings and vendor discussions to refine feasibility.

Contribution

• Problem framing and constraint capture
• Route concepts and system block diagrams
• Robot configuration comparison
• Stakeholder presentations and follow-up studies

Outcome

• Narrowed the study to feasible movement concepts.
• Made operational constraints visible for vendor evaluation.
• Built a basis for requirements and safety review.

Challenge

Printers, a weighing scale, payment hardware, touchscreen, router, PC, and mailbox had to become one usable, safe, and serviceable self-service terminal.

Approach

• Created three concepts from separated modules to full integration.
• Iterated layouts around ergonomics, access, safety, and cable routing.
• Produced CAD geometry, drawings, and fit studies.
• Used a physical mock-up and fabricator feedback before assembly.

Contribution

• Fusion 360 and SolidWorks modelling
• Component packaging and service-access studies
• Prototype and slot-fit testing
• Fabricator coordination and documentation

Outcome

• Progressed from concepts to a fabricated enclosure.
• Integrated the shell and equipment into a completed assembly.
• Improved maintainability through access and routing design.

Challenge

Teams had to build interconnected arenas their own robot could navigate while creating obstacles for competitors, balancing challenge, feasibility, and reliable autonomy.

Approach

• Translated the competition objective into arena and navigation requirements.
• Iterated a Merlion Park-inspired design in Fusion 360.
• Built a dimensionally accurate mock-up to test clearances.
• Fabricated the arena, mapped it in RViz, and tested navigation.

Contribution

• Systems approach and requirements
• Arena CAD and physical iteration
• Mock-up and feasibility testing
• ROS mapping and robot navigation

Outcome

• Delivered the fabricated competition arena.
• Created a usable RViz map.
• Demonstrated LIMO navigation through the completed environment.

Challenge

Repositioning larger or bed-bound patients can require multiple nurses, creating physical strain and time pressure. Existing aids may depend on patient mobility, fixed infrastructure, or multiple products.

Approach

• Selected the nursing domain through an agile comparison process.
• Interviewed nurses and validated bedside needs and constraints.
• Reviewed injury evidence and competing turning aids.
• Converted needs into requirements, modelled the concept, and built the prototype.
• Ran hands-on stakeholder validation.

Contribution

• Domain analysis and stakeholder interviews
• Needs formation and market comparison
• Concept and SolidWorks modelling
• Prototype assembly and feedback analysis

Outcome

• Demonstrated assisted patient rotation.
• Received positive feedback on the concept.
• Identified inflation time and patient movement as key improvement areas.
• Defined faster pumping, higher-friction material, and automated valves as next steps.
