A freight transport vehicle comprising: - a frame defining a loading area and having a longitudinal median axis lying on a vertical median plane ; - a plurality of independent steering trolleys forming two rows , of trolleys, arranged on opposite sides of said vertical median plane in a position spaced from the vertical median plane ; each trolley having at least one wheel rotating about a rolling axis and designed to roll in contact with a rolling surface , and being rotatably hinged to the frame about a respective vertical hinge axis orthogonal to said rolling axis ; - for each of said trolleys , a respective steering motor for rotating said trolley with respect to said frame about the respective vertical hinge axis ; and - a drive and control unit of said motors to drive the frame with reference to a reference trajectory along said rolling surface ; said drive and control unit comprising detection means to detect a deviation of the vehicle from said reference trajectory during the progress of the vehicle and a processing and control unit configured to control said motors in response to detection signals received from said detection means ; characterized in that said detection means comprising two independent optical detectors ; each of said optical detectors being designed to send a respective deviation signal with respect to a reference condition to said processing and control unit ; said optical detectors being both crossed by said vertical median plane and mutually spaced along said median symmetry axis ; said processing and control unit being configured to process the received deviation signals and determine a centre of instantaneous rotation of the vehicle and to control at least part of the motors and rotate the relative trolleys , each about its own vertical hinge axis , so that all the rolling axes intersect in said centre of instantaneous rotation . - a frame defining a loading area and having a longitudinal median axis lying on a vertical median plane ; - a plurality of independent steering trolleys forming two rows , of trolleys, arranged on opposite sides of said vertical median plane in a position spaced from the vertical median plane ; each trolley having at least one wheel rotating about a rolling axis and designed to roll in contact with a rolling surface , and being rotatably hinged to the frame about a respective vertical hinge axis orthogonal to said rolling axis ; - for each of said trolleys , a respective steering motor for rotating said trolley with respect to said frame about the respective vertical hinge axis ; and - a drive and control unit of said motors to drive the frame with reference to a reference trajectory along said rolling surface ; said drive and control unit comprising detection means to detect a deviation of the vehicle from said reference trajectory during the progress of the vehicle and a processing and control unit configured to control said motors in response to detection signals received from said detection means ; characterized in that said detection means comprising two independent optical detectors ; each of said optical detectors being designed to send a respective deviation signal with respect to a reference condition to said processing and control unit ; said optical detectors being both crossed by said vertical median plane and mutually spaced along said median symmetry axis ; said processing and control unit being configured to process the received deviation signals and determine a centre of instantaneous rotation of the vehicle and to control at least part of the motors and rotate the relative trolleys , each about its own vertical hinge axis , so that all the rolling axes intersect in said centre of instantaneous rotation . <EOS>
