  • Patent number: 6154690
    Abstract: A multi-feature automated wheelchair and method provides a significant degree of mobility for the mobility impaired, with minimum human intervention. The wheelchair is constructed to provide a therapeutic effect and is calibrated to accommodate at least three seating configurations for a specific user. The wheelchair is motor driven via a control assembly for activating and controlling wheel rotation. The control assembly includes a joy stick controller for controlling both the speed and direction of motion of the wheelchair, respectively. At least one actuator is used for activating a seat, back, head, at least one leg and at least one arm rest as independent moveable elements. Three separate controllers are optionally used for transmitting emergency data, activating an alarm system, and adjusting the relative heights of the seat, back and head rest portions of the wheelchair.
