Abstract
A conveyance apparatus comprises a first movable device to move while holding an object, a second movable device to move while holding the object and transfer the object to the first movable device, and a controller to control the first and second movable devices. The second movable device includes a guide member and a hand arranged so as to be capable of reciprocally moving along the guide member while holding the object. The controller estimates, based on a driving history of the second movable device, a thermal deformation amount of the guide member corresponding to the reciprocal movement of the hand along the guide member, and corrects, based on the estimated thermal deformation amount, a drive command value used to move the first movable device to a position to receive the object from the second movable device.
