Abstract: Advances in robotics have had a great influence in the design and performance of motorized assistive devices in the past two decades. Specifically, introduction of “intelligent” system technologies has enabled users of motorized assistive devices to better control their machines and avoid problematic situations. However, one area of assistive devices that has not reaped the benefits of advances in the state-of-the-art, is major weight reduction in the overall design of these devices. Bulky motorized assistive devices hinder the range and portability of these devices and impact the ability of the user to manually handle these devices without assistance of mechanical lifting devices or individuals. This ultralight, collapsible powered operated vehicle (POV) is lighter than those available today by approximately 80%. This device addresses this issue by the development of an ultralight, collapsible POV, which will replace the bulky and heavy motorized assistive devices currently being used.
