| 摘要 |
The present invention relates to a mobile vehicle or wheelchair having the ability to provide stabilized transport to at least one individual on a variety of surfaces, slopes and/or terrains. The mobile unit or wheelchair of the invention may travel across smooth and very rough surfaces, slopes of varying or different angles and various outdoor terrains (including grassy, rocky, sandy, muddy and/or hilly terrains). In one aspect of the invention, the height of any part of the unit or the overall height of the device may be adjusted preferably to raise or lower the center of gravity. For example, the height of the device may be lowered to provide more stable transportation. In another aspect, the device may be adjusted to increase or decrease the size of the footprint (or any part of the footprint) of the device. For example, the footprint of the device may be enlarged to provide more stable transportation. Preferably, both the height of the device (or any part of the device) and the size of the footprint (or any part of the footprint) may be adjusted preferably to provide more stability.
