Abstract: A wheelchair includes a seat, a first adjustable leg coupled to a first side of the seat, a second adjustable leg coupled to a second side of the seat, one or more turning sensors, and a control unit. The first adjustable leg includes a first leg actuator configured to extend and retract the first adjustable leg. The second adjustable leg includes a second leg actuator configured to extend and retract the second adjustable leg. The one or more turning sensors are configured to output a turning signal indicative of the wheelchair performing a turning motion. The control unit is operable to determine the wheelchair is performing the turning motion based on the turning signal, and automatically adjust a tilt angle of the seat with the first leg actuator and the second leg actuator to lean a user of the wheelchair into the turning motion.
