REMOTE-CONTROLLED WORK MACHINE

WIPO Patent Application WO/2015/155878

A1

The present invention relates to a work vehicle which is controlled by remote operations. In remote operations of the work vehicle, i.e. a construction machine or the like, vehicle-body vibration information is made perceptible to an operator in a remote location. The present invention addresses the problem of reducing the likelihood of the operator suffering from motion sickness by transmitting the vehicle-body vibration information after removing motion-sickness-causing frequencies therefrom, when making the vehicle-body vibration information perceptible to the operator. Accordingly, the present invention is characterized by being configured from: sensors for detecting a construction machine and construction-machine vibration information; a band removal device for removing motion-sickness-causing frequencies from the detected vibration information; a camera for imaging the state of the periphery of the construction machine; a remote cockpit in which an operator sits; and an actuator for driving the remote cockpit. The present invention is further characterized in that the actuator for driving the remote cockpit is driven using the vibration information which has had the motion-sickness-causing frequencies removed therefrom, to reproduce the construction-machine vibration information.
