An effectiveness of model-based development with user model in developing a wheelchair robot with an ability of telepresence

This paper shows an effectiveness of the model-based development with a user model. The user model which we propose is effective for designing a product, because the user model indicates the requirements for product. And the user model is effective also for evaluating the product, because the user model behaves as an agency of the actual user in the simulation environment. Therefore, the user model is efficient for developing a product which involves some risks damaging user, and is efficient also for developing the product which is used by different types of users, because as a behalf of each user, the user model can evaluate the product. In order to prove the effectiveness of this method, we applied this method to a development of a wheelchair robot with an ability of telepresence.
