    John, I don't think you need any motors. From the exciting photo of Athena standing with a walker, it looks like she just needs a safety system to support her in case she starts to fall.

    You could just run steel cables 2 in parallel (orange) and then a third cable (green) perpendicularly to the other 2 (see drawing). Then Athena could be safety harnessed to this third cable (blue) giving her total free x y movement.
    Inside, I would make sure to eye bolt into studs in the walls. Better yet, put a 2x4 between 2 wall studs and put the eye bolt into that in new between stud. For the harness connection to the third cable(green) you would need a strong swivel connector giving Athena 360 turning ability. If you could find a swivel connection that can disconnect quickly, then you could have this sort of rig in the rooms she would like to use. The parts for an entire room are probably under $50.

    Outside you could use poles to support the 2 parallel cables giving her outside access with safety.

    The (green) cable would move left to right (lets call this X movement) in the room along the (orange) cables. The (blue) harness would move in the perpendicular direction (Y axis) along the (green) cable. With a swivel connection she could also rotate freely.
