A personal guided transport vehicle is disclosed to include a horizontal motion unit, a vertical motion unit, and a gear set coupled between a shaft of the horizontal motion unit and a shaft of the vertical motion unit for enabling the shafts to be interlocked. When operating a horizontal operating lever of the horizontal motion unit, a lock pin is forced into engagement with a mounting hole of the shaft of the vertical motion unit. The horizontal motion unit and the vertical motion unit each have a spring plunger for self-lock. A docking mechanism is disclosed to enable the vehicle to be easily positioned in a docking flange. The docking mechanism includes a locating plate and a coupling plate, the locating plate having a locating notch for quick alignment, the coupling plate having hooks for hooking on the docking flange to hold the vehicle in position.
