Hands-Free Stroller Attachment Device Design & Testing

Capstone Design Project (July- December 2024)- Sponsored by Heather Hayes (CEO of StrollRunner)

Stroller attachment device SolidWorks Assembly Model

Final Assembled Stroller Attachment Device

Prototype attached to the stroller handle at device and user interface.

Setup to test for front wheel lifting of the stroller with prototype attached using gyroscopic linear acceleration data.

Biomechanical parameters were analyzed using Motion Capture Analysis.

Our final prototype showed reduced biomechanical effects compared to non-hands-free stroller running.

Our final prototype showed reduced front wheel lifting compared to the original StrollRunner.
