One of our incredibly talented senior design team completing the Off-Road Pediatric Walker in December 2020. Despite many setbacks and challenges during a pandemic, the team designed, manufactured and tested the new walker add-ons to improve off-road mobility without compromising safety or usability.

To improve the user’s mobility, the team designed and manufactured interchangeable wheel hubs that can be easily installable on R82’s Crocodile walker.  These hubs interface with wheel extensions that allow the walker to be quickly adapted to specific terrain.  Additionally, the team replaced the Crocodile’s front casters with casters designed to house a larger, pneumatic wheel.

To ensure the user’s safety, the hub has an integrated braking and anti-rollback system that can be engaged by the user.  Additionally, all the hub components can support the weight of any Crocodile user.

The team also designed and manufactured a lightweight hammock seat that is easily installable on the Crocodile.  The seat does not interfere with the user’s experience when not in use, but can be easily engaged to comfortably support the user.

Grace, an active seven-year-old who loves playing soccer, has been using the team’s add-ons on her Crocodile walker.  According to Grace’s father, the walker’s improved mobility will not only help her on the soccer field but will also allow her to participate in a variety of new outdoor activities.
