A mobile apparatus capable of moving or acting autonomously while flexibly avoiding contact with a moving object in accordance with various situations is provided. In a case where a second safety condition is not satisfied because, e.g., a first target trajectory cannot be found, a second target trajectory causing a first spatial element to approach the boundary of an element passing region is searched for and determined.
