The Chattahoochee High School InvenTeam invented an after-market device to enable continuous mobility for adolescents using manual wheelchairs. The All-Terrain Accessibility Transporter (ATAT) allows manual wheelchairs to be stabilized on slopes of up to forty-five degrees and on rugged terrain at beaches or parks. Also, it can tread up a flight of stairs with a height of up to 6 inches per step. The device is easy to store and transport in the bed of pickup trucks and wheelchair-accessible vans with dimensions of 48.7” x 50”. The ATAT control system uses a joystick for chassis movement and buttons for the wheelchair lift. The control system is powered by a 12 V, 18 amp-hour battery with a life of up to 6 hours per charge. The device is suitable for individuals up to 170 pounds using a manual wheelchair. It is made from aluminum sheet metal for a stronger, lighter chassis and V-belt treads for strength and ability to latch onto stairs and rugged terrains.
