Abstract
A gripping device is configured to assemble a connector to a vehicle. An automatic connector assembling system may use the gripping device, and capture a two-dimensional image of an input connector or an output connector of each of a plurality of wiring connectors by a vision camera, detect a position of the input connector or the output connector detect a three-dimensional precise position and angle of the input connector or the output connector by moving the vision camera grip the input connector or the output connector for inserting and fastening the input connector or the output connector into a connection port of an electrical component.
