Abstract: Provided are an information processing apparatus and a mobile robot configured so that influence of a change in the posture of a mobile body can be reduced and the accuracy of measurement of a distance to a target object can be improved. A mobile robot 1 includes a control section 2 configured to drivably control each unit of a robot body 1A, a detection section 3 configured to detect a target object around the robot body 1A, and a mobile section 4 configured to move the robot body 1A. The detection section 3 includes first distance sensors 31 configured to detect distances to first positions P1 on a floor surface F in a movement direction D1 of the robot body 1A and second distance sensors 32 configured to detect distances to second positions P2.

Abstract: A mobile robot 1 includes: a control means 2 for controlling the drive of each unit of a robot body 1A; a detection means 3 for detecting a target object around the robot body 1A; and a travel means 4 for moving the robot body 1A. The control means 2 determines a change in the environment by: obtaining two first measurement value groups S11 and S12 obtained by detecting the distances to different positions P1 and P2 in an environment at intervals of a predetermined time with the travel of the mobile robot 1; and processing the first measurement value groups, generating two second measurement value groups S21 and S22 according to the travel distance of the mobile robot 1, and comparing the generated second measurement value groups S21 and S22.
