A remote control system comprising: a slave robot configured to move in conjunction with a change in a posture of an operator; a capture device configured to acquire a signal indicating a posture of an operator 's body; and a control apparatus, wherein the control apparatus includes: a receiving controller configured to receive a signal indicating a posture of the slave robot from the slave robot and to receive the signal indicating the posture of the operator 's body from the capture device, a posture comparing part configured to acquire a posture error indicating a difference between the posture of the slave robot and the posture of the operator, a motion connecting part configured to transmit, to the slave robot, an operation signal for operating the slave robot generated on the basis of the change in the posture of the operator on a condition that the posture error is within a predetermined threshold range, the motion connecting part configured to transmit an operation signal for operating the slave robot so that the posture error becomes within a predetermined threshold range before starting the synchronization between the motion of the operator and the motion of the slave robot, characterized in that the control apparatus further includes a connecting information presenting part configured to present information to the operator to prompt the operator to stay still while the slave robot is moving in order to reduce the posture error before starting the synchronization between the motion of the operator and the motion of the slave robot. a slave robot configured to move in conjunction with a change in a posture of an operator; a capture device configured to acquire a signal indicating a posture of an operator 's body; and a control apparatus, wherein the control apparatus includes: a receiving controller configured to receive a signal indicating a posture of the slave robot from the slave robot and to receive the signal indicating the posture of the operator 's body from the capture device, a posture comparing part configured to acquire a posture error indicating a difference between the posture of the slave robot and the posture of the operator, a motion connecting part configured to transmit, to the slave robot, an operation signal for operating the slave robot generated on the basis of the change in the posture of the operator on a condition that the posture error is within a predetermined threshold range, the motion connecting part configured to transmit an operation signal for operating the slave robot so that the posture error becomes within a predetermined threshold range before starting the synchronization between the motion of the operator and the motion of the slave robot, characterized in that the control apparatus further includes a connecting information presenting part configured to present information to the operator to prompt the operator to stay still while the slave robot is moving in order to reduce the posture error before starting the synchronization between the motion of the operator and the motion of the slave robot. a receiving controller configured to receive a signal indicating a posture of the slave robot from the slave robot and to receive the signal indicating the posture of the operator 's body from the capture device, a posture comparing part configured to acquire a posture error indicating a difference between the posture of the slave robot and the posture of the operator, a motion connecting part configured to transmit, to the slave robot, an operation signal for operating the slave robot generated on the basis of the change in the posture of the operator on a condition that the posture error is within a predetermined threshold range, the motion connecting part configured to transmit an operation signal for operating the slave robot so that the posture error becomes within a predetermined threshold range before starting the synchronization between the motion of the operator and the motion of the slave robot, characterized in that the control apparatus further includes a connecting information presenting part configured to present information to the operator to prompt the operator to stay still while the slave robot is moving in order to reduce the posture error before starting the synchronization between the motion of the operator and the motion of the slave robot.
