1. A free-moving transport carriage for conveying at least one workpiece along a conveying route in variable conveying directions, comprising:
a) a chassis, which defines a main axis and a main alignment of the free-moving transport carriage, a fastening device for at least one workpiece and a connecting device which couples the chassis to the fastening device;
b) a control device which is designed to control the chassis along the conveying route depending on position information which is provided by at least one position information transmitter;
and
c) a near-field sensor arrangement which can be coupled to a track control unit, wherein, via position raw information which can be determined by the near-field sensor arrangement, the track control unit can determine a relative position of one or more points of the free-moving transport carriage with regard to one or more position information sources of a near-field movement environment, the track control unit being configured to temporarily disable the control device to autonomously control and guide the chassis along at least a portion of the conveying route; and
d) the main alignment of the free-moving transport carriage and a conveying direction can be adapted to one another by the track control unit.
