This is Wheel bot. It can roam around the house in its wheel form and detect standing fatigue by camera and other sensors. It would then automatically go towards the person and transform to chair form and provide comfort without having a house owner to grab a chair him/herself. With its simple transformation, it is also durable and strong enough to support the weight by the user. The inflatable cushion can be command at will and would not obstruct any part or cause conjunctions.
