Upper Darby High School InvenTeam
Drexel Hill, PA
- A total of 72 dual-layer polyurethane rollers – set on fins at 45-degree angles – circumscribe each stainless-steel hub that comprises the omni-directional wheelchair.
- A three-access joint stick coupled with encoders mounted on each drive shaft allow infinite direction, while ensuring precise control of speed and direction of each wheel.
- The powered chair also has the ability to raise and lower its height, tilt the seat, and raise and lower the footrest.
- Demonstrated at the Odyssey, the InvenTeam’s omni-directional wheelchair illustrated full maneuverability through translational, lateral and rotational movements including moving in diagonals at any angle and tracing an arch.
- There is potential to further develop the prototype in collaboration with the company Airtrax, which provided additional support for the InvenTeam.
