Document Type and Number:
WIPO Patent Application WO/2020/054649
Kind Code:
A1
Abstract:
Provided is a conveyance system or the like in which a contribution can be made to stable conveyance of various forms of conveyance objects as they are, without being modified or relocated. The conveyance system conveys a conveyance object while holding the conveyance object between a plurality of conveyance robots. The conveyance robots are each provided with: a body; wheels; a contact part which comes into contact with the conveyance object; a turning mechanism through which the contact part is turnably attached to the body; a driving unit which is attached to the body and which drives the wheels; a load sensor which detects a load when the contact part comes into contact with the conveyance object; and an angle sensor which detects the rotational angle of the contact part with respect to the body. By use of a hardware resource, a process for controlling the driving unit on the basis of information concerning the load detected by the load sensor and the rotational angle detected by the angle sensor such that the load and the rotational angle approach a first target value and a second target value, is executed.
