However, the cost of the amount of height is needed because of securing the place and breeding of the horse, etc. Under such circumstances, we have created a horseback riding robot as a simulator that can realize the horseback riding therapy, and have added scientific analysis to the empirical rule of horseback riding therapy to study its usefulness. In this paper, we introduce a new simple horse-riding model. This simple horse-riding model was developed using the test data in a past, and it can be used even in the home.
