Claim 1:
2. A remote operation system in which a plurality of users who are present in locations away from each other remotely operate a plurality of respective remote operation mobile bodies that are located in one place by operating respective remote operation terminals that the plurality of users have, the remove operation system comprising:
the plurality of remote operation mobile bodies; and
the plurality of remote operation terminals, wherein
each of the remote operation mobile bodies comprises:
a control command reception unit configured to receive a control command from the corresponding remote operation terminal;
an operation control unit configured to control the operation of the own remote operation mobile body based on the control command;
an imaging unit;
a captured image information acquisition unit configured to acquire captured image information from the imaging unit;
a captured image information transmission unit configured to transmit the captured image information to the corresponding remote operation terminal;
a mobile-body-side microphone;
a mobile-body-side sound pressure information acquisition unit configured to acquire sound pressure information from the mobile-body-side microphone;
a mobile-body-side sound pressure information transmission unit configured to transmit the sound pressure information acquired by the mobile-body-side sound pressure information acquisition unit to the corresponding remote operation terminal;
a mobile-body-side sound pressure information reception unit configured to receive sound pressure information from the corresponding remote operation terminal; and
a mobile-body-side output unit configured to output the sound pressure information received by the mobile-body-side sound pressure information reception unit, and

each of the remote operation terminals comprises:
a control command input unit configured to accept an operation of inputting the control command;
a control command transmission unit configured to transmit the control command to the corresponding remote operation mobile body;
a captured image information reception unit configured to receive the captured image information from the corresponding remote operation mobile body;
a captured image information display unit configured to display the captured image information;
a terminal-side microphone;
a terminal-side sound pressure information acquisition unit configured to acquire sound pressure information from the terminal-side microphone;
a first-terminal-side sound pressure information transmission unit configured to transmit the sound pressure information acquired by the terminal-side sound pressure information acquisition unit to the corresponding remote operation mobile body;
a first-terminal-side sound pressure information reception unit configured to receive sound pressure information from the corresponding remote operation mobile body;
a second-terminal-side sound pressure information transmission unit configured to transmit the sound pressure information acquired by the terminal-side sound pressure information acquisition unit to another remote operation terminal;
a second-terminal-side sound pressure information reception unit configured to receive sound pressure information from another remote operation terminal;
a terminal-side output unit configured to output the sound pressure information received by the first-terminal-side sound pressure information reception unit or the second-terminal-side sound pressure information reception unit; and
a conversation control unit configured to execute an inter-mobile-body conversation mode that establishes conversation with another user using the first-terminal-side sound pressure information transmission unit and the first-terminal-side sound pressure information reception unit and an inter-terminal conversation mode that establishes conversation with another user using the second-terminal-side sound pressure information transmission unit and the second-terminal-side sound pressure information reception unit in such a way that they can be switched, wherein

each of the remote operation terminals further comprises:
an inter-terminal conversation request transmission unit configured to transmit an inter-terminal conversation request to another remote operation terminal;
an inter-terminal conversation request reception unit configured to receive an inter-terminal conversation request from another remote operation terminal; and
an inter-terminal conversation request approval unit configured to accept an operation of approving the inter-terminal conversation request received from another remote operation terminal, and

the conversation control unit of each of the remote operation terminals executes the inter-terminal conversation mode in place of the inter-mobile-body conversation mode after the inter-terminal conversation request is approved.
