Abstract
A mobile robot system capable of estimating the occurrence of various risks within its environment and executing appropriate processing to achieve an objective is provided. The mobile robot system includes an environment recognition unit for recognizing an external environment, a travelling unit, and a travelling control unit which controls the travelling unit on the basis of environment information from the environment recognition unit. The mobile robot system also includes a calculation unit which generates a travelling command to the travelling control unit, a potential risk area recognition unit, and a risk occurrence condition detection unit. When a risk occurrence condition is satisfied, the calculation unit calculates a degree of influence of the occurring risk on achievement of an objective quantitatively in each stage. When the possibility of achieving the object is low, a movement planning unit replans a moving route to raise the possibility of achieving the objective.
