My key responsibilities including:

- Material testing for the rubber handle to ensure ergonomic comfort, grip performance, and durability in industrial settings.

- User testing for the easy-swap battery system (as shown above), assessing usability, handling comfort, and operational efficiency.

- UI design for onboard interface components to improve operator interaction and feedback.

Additionally, I participated in WP Series quality checks collaborating with engineering and manufacturing teams to align product performance with design intent and quality standards.
