A robotic wheelchair with a combination of different locomotion for difficult terrains

Over the years, a lot has been done in the field of medical technology to assist the elderly and physically challenged people. One such development is the robotic wheelchair. Many designs of the same have been proposed throughout the recent past. But such models still face difficulties in covering difficult terrains like steps, etc. We propose a design of wheelchair which will be able to mimic easy locomotion techniques available in nature. For example: serpentine locomotion, aquatic locomotion, etc. Various types of robots mimicking such movements have been made in the past. We suggest the inclusion of such robotic locomotors in the already existing robotic wheelchair designs to assist more efficient movement. A peep into the previous researches done in this field lays the foundation of our proposed design.
