Abstract
A powered wheelchair includes a seat, a first leg, a second leg, and a control unit. The first leg includes a first inertial measurement unit configured to determine a position of the first leg and a first leg actuator configured to adjust a position of the first leg. The second leg includes a second inertial measurement unit configured to determine a position of the second leg and a second leg actuator configured to adjust a position of the second leg. The control unit is operable to determine a global orientation of the powered wheelchair by averaging the position of first leg and the position of the second leg, and automatically adjusting the position of the first leg with a first leg actuator and the position of the second leg with the second leg actuator based on the global orientation to maintain the seat in a pre-selected position.
