[0078] Place the required items on the tracking cart 1 and tie them with the tightening belt 15. After the required items are tied, the RFID signal receiving bracelet 18 or the smart phone sends a command to release the brake and move to the tracking cart 1 through the APP. The tracking cart 1 drives the built-in motor to turn the steering wheel 3 to track and identify the target at the set safety distance and move. When the user needs to use the tracking cart 1 again, he / she operates according to the above method. When the tracking cart 1 is not in use, the power of the tracking cart 1 is turned off and the tracking cart 1 is folded up.

[0079] When step-crossing is not required, the two U-shaped frames 111 are arranged at 90°, with the vertical U-shaped frame 111 attached to the side wall of the tracking trolley 1, and the lifting member 130 housed within the tracking trolley 1. When step-crossing is required, both U-shaped frames 111 are arranged horizontally. When both U-shaped frames 111 are arranged horizontally, iron rods are inserted into the corresponding limiting holes on the limiting plates 115 to complete the positioning of the two U-shaped frames 111.

[0080] Take the step up as an example:

[0081] After completing the limiting operation of the two U-shaped frames 111, the intelligent control module 4 controls the lifting member 130 stuck on the rectangular frame 121 to rise until the bottom end of the tracking trolley 1 is higher than the step, and then controls the lifting member 130 on the U-shaped frame 111 where the rectangular frame 121 is located to move until its support legs 137 touch the ground. Secondly, the lifting member 130 on the other U-shaped frame 111 is controlled to move until its support legs 137 touch the step. Finally, the drive motor 141 is controlled to work. When the drive motor 141 rotates, the rectangular frame 121 is pulled from the U-shaped groove 112 of one U-shaped frame 111 to the U-shaped groove 112 of the other U-shaped frame 111 through the rope to complete the step crossing.

[0082] When continuing to ascend the stairs:

[0083] First, the lifting member 130 on the rectangular frame 121 rises until the bottom end of the tracking trolley 1 is higher than the step to be crossed. Secondly, the drive motor 141 works. When the drive motor 141 rotates, the U-shaped frame away from the rectangular frame 121 is pulled toward the tracking trolley 1 through the rope. Then, the lifting member 130 on the rectangular frame 121 descends, and the ground is completely supported by the lifting member 130 on the outer frame 110. Then, the tracking trolley 1 is pulled toward the step to be crossed by the drive motor 141.
