Material vehicle, traction apparatus and system, and method for controlling bidirectional traveling of material vehicle

Abstract

A material vehicle, a traction apparatus and system, a method for controlling the bidirectional traveling of a material vehicle, and a storage medium. A material vehicle () comprises a vehicle body (), an unlocking assembly (), a plurality of front universal wheels () and a plurality of rear universal wheels (), wherein the plurality of front universal wheels () and the plurality of rear universal wheels () are all in a locked state; the vehicle body () is used for placing a target article; the unlocking assembly () is used for releasing the plurality of front universal wheels () from the locked state when same are in a horizontal rotation direction, and controlling the material vehicle () to travel in a first direction by means of the plurality of front universal wheels (); and the unlocking assembly () is further used for releasing the plurality of rear universal wheels () from the locked state when same are in the horizontal rotation direction, and controlling the material vehicle () to travel in a second direction by means of the plurality of rear universal wheels (), the first direction and the second direction being opposite to each other. By means of the unlocking assembly, the plurality of front universal wheels or the plurality of rear universal wheels can be released from the locked state thereof, such that the material vehicle can change the positions of driving wheels, and bidirectional traveling can be realized without needing to turn the material vehicle around.
