[0018] The visual sensor 40 is fixedly disposed on one side of the vehicle body handle 11 to provide visual data.

[0019] The basket 50 is fixedly disposed above the vehicle body base 10 and is used to place shopping bags and merchandise.

[0020] The barcode scanning module 60 is disposed in the basket 50 and is used to scan the barcode of the commodity.

[0021] The magnetization and demagnetization module 70 is disposed in the basket 50 and is used to magnetize or demagnetize the goods.

[0022] The barcode scanning module 60 and the magnetizing and demagnetizing module 70 are also connected to the shopper's mobile phone through a mobile phone APP to provide product information and perform real-time pricing and online payment.

[0023] The automatic packing module comprises two guide rails 81 symmetrically fixed on the inner side of the basket and a transverse guide rail 82 arranged between the two guide rails.

[0024] The control module 90 is disposed below the vehicle body base 10 and is in communication connection with the visual sensor 40 and the motor 30 .

[0025] The control module 90 controls the motor 30 to drive the Mecanum wheel 20 to move according to the visual data provided by the visual sensor 40 to follow the customer and avoid obstacles autonomously.

[0026] Figure 2 It is a structural diagram of the automatic packaging module in an embodiment of the present invention.
