Development of four-wheel-type mobile robot for rough terrain and verification of its fundamental capability of moving on rough terrain

In many fields employing robots, e.g., wheelchair robots, rescue robots, and construction robots, robots that can move on rough terrains are desired. A robot with a simple mechanism and high mobility for all terrains is discussed in this paper. A four-wheel-type mobile robot is developed, and its design is discussed from a functional viewpoint. Its fundamental capability of moving on rough terrains is verified through simulations and experiments.
