PROJECTS

Mechanical Claw Machine

Claw - Lead Designer | Jan 2025 - May 2025

SITUATION:

  • Machine Design – Class project

TASK:

  • Create a purely mechanical device (no electricity) that performs a useful task

  • Requirements: motion conversion, integration of gears, linkages, fasteners, shafts, and additional components

ACTION:

  • Designed the claw mechanism in SolidWorks, meeting all functional requirements

  • Fabricated components through 3D printing and laser cutting to achieve accuracy and functionality
