A system for providing a behavior simulation platform service is provided, and comprises: a user terminal that selects and downloads at least one behavior simulation program, and then applies the at least one behavior simulation program to a previously owned robot; and a platform service provision server including a database unit that maps and stores the at least one behavior simulation program and at least one robot, a transmission unit that, if the user terminal selects a behavior simulation program, transmits the selected behavior simulation program to the user terminal, and a storage unit that, if feedback is received from the previously owned robot via the user terminal, stores the feedback.
