Problem Statement

For my Master's Capstone, I spearheaded the design of an omnidirectional treadmill - a treadmill that enables walking in any direction for an interactive rehabilitation experience through VR gaming.

My role was to evolve a consumer product concept into an engineering prototype (MVP) by designing for manufacturability, safety, and functionality. By applying my design, prototyping, and collaboration skills, I fully improved the prototype's strength, drive system's efficiency, motion, frame structure, and cost.

Here you can view the original prototype's issues: loose belts, incomplete frame, instability, and many more:

Design Improvements

Through rapid prototyping and testing, I implemented my improvements to the treadmill's drive system, walking beams, and supports to enhance stability, strength, and user experience.

Manufacturing

After extensive DFM and FEA, I led the manufacturing of each new component, communicating with machinists and overseas manufacturers to fabricate 400+ components out of Steel 1018 using CNC machining and horizontal bandsaws while adhering to GD&T standards.

Results

My team and I completed the project, creating a fully functional treadmill prototype after months of testing and manufacturing. The beams can now smoothly rotate throughout the whole system, enabling continuous walking in any direction.
