Abstract
The present invention provides an unmanned transfer robot system including: an unmanned transfer vehicle capable of traveling on a road surface between a plurality of work stations; a robot that is mounted on the unmanned transfer vehicle; a sensor that is mounted on the robot and that detects a condition of the road surface; and a control unit that controls the robot and the unmanned transfer vehicle. Within an operation range of the robot, the sensor is disposed at a position where the sensor can detect a condition of the road surface in the periphery of the unmanned transfer vehicle, and the control unit controls the unmanned transfer vehicle on the basis of the condition of the road surface acquired by the sensor.
Claims7
An unmanned transfer robot system comprising:
- an unmanned transfer vehicle that travels on a predetermined traveling path;
- a robot that is mounted on the unmanned transfer vehicle;
- a sensor that is mounted on the robot and that has a predetermined detection range;
- and
- a controller that controls the robot and the unmanned transfer vehicle,
- wherein the controller:
- operates the robot during traveling of the unmanned transfer vehicle so that a road surface in front of the unmanned transfer vehicle in an advancing direction is included in the predetermined detection range, the road surface in front of the unmanned transfer vehicle in the advancing direction being determined by the predetermined traveling path;
- calculates an amplitude of a vibration predicted to be generated in the unmanned transfer vehicle on the basis of a condition of the road surface detected by the sensor;
- estimates a maximum value of a traveling speed of the unmanned transfer vehicle, the maximum value of the traveling speed making the calculated amplitude of the vibration equal or less than a prescribed threshold;
- and
- controls the unmanned transfer vehicle on the basis of the estimated maximum value.
