Remote operation system

A remote operation system comprising:

• a working machine including an actuation lever and an imaging device which images an environment including at least a part of the actuation lever;
• and
• a first remote operation apparatus and a second remote operation apparatus each including an operation lever configured to perform a remote operation of the working machine, an image output device which displays an environmental image corresponding to captured image data acquired by the imaging device of the working machine, and one or more processors configured to execute computer-executable instructions stored in a memory, wherein
• the one or more processors of the first remote operation apparatus execute the computer executable instructions to cause the first remote operation apparatus to act as a passive mode detector which detects a passive mode of the operation lever in the first remote operation apparatus, and a first client control device which transmits operational mode data corresponding to the passive mode of the operation lever in the first remote operation apparatus which is detected by the passive mode detector, and
• the second remote operation apparatus further comprises an actuator configured to actively operate the operation lever in the second remote operation apparatus, and wherein one or more processors of the second remote operation apparatus execute the computer executable instructions to cause the second remote operation apparatus to act as a second client control device which receives the operational mode data, and controls an operation of the actuator in accordance with the passive mode of the operation lever in the first remote operation apparatus in response to the operational mode data.
