Information processing device and information processing method

An information processing method comprising, by a processor:

• transmit a control command value to an autonomous moving body;
• receiving a movement result of the autonomous moving body based on the control command value and continually or inters intermittently receive a movement log of the autonomous moving body based on the control command value;
• and
• approximating a motion characteristic parameter of a simulator model for a movement simulation of the autonomous moving body on a basis of the movement result of the autonomous moving body and reapproximate the motion characteristic parameter on a basis of the movement log and on a basis of elapsed time from date and time of execution of automatic approximation last time,
• wherein the approximating further includes approximating the motion characteristic parameter on a basis of similarity between a plurality of simulation results acquired on a basis of the different motion characteristic parameters in the movement simulation based on the control command value, and the movement result of the autonomous moving body.
