The meal delivery robot 1000 includes a case 100 of the meal delivery robot and a robot body 200, and the robot body 200 is connected to the case 100 of the meal delivery robot. Wherein the case 100 of the meal delivery robot is used for storing meal.

Fig. 2 is a schematic structural diagram of a robot body according to an embodiment of the application. Fig. 3 is a schematic structural diagram of a meal delivery robot according to an embodiment of the application. As shown in fig. 3, an L-shaped stopper 70 is provided on the box 100 of the meal delivery robot, a lifting device 210 and a top plate 220 are provided on the robot body 200, and the robot body 200 and the box 100 of the meal delivery robot are connected by the L-shaped stopper 70 and the top plate 220; the lifting device 210 is used for making the top plate 220 contact with the L-shaped limiting member 70.

The robot body 200 is provided with a sensor device and a control device. In an operation process, when the sensing device senses that the robot body 200 is located at the bottom of the box 100 of the meal delivery robot, the control device automatically controls the lifting device 210 to lift, and the lifting device 210 lifts the box 100 of the meal delivery robot. During the process that the box body 100 of the meal delivery robot is lifted, the L-shaped stopper 70 gradually approaches the top plate 220. When the L-shaped stopper 70 abuts against the top plate 220, the control device automatically controls the lifting device 210 to stop lifting.

In one embodiment, the L-shaped limiting member 70 is provided with a magnet, and the top plate 220 is made of metal. At this time, when the L-shaped stopper 70 is adsorbed on the top plate 220, it indicates that the L-shaped stopper 70 has abutted against the top plate 220.

Wherein, the transportation bracket 300 is provided with an L-shaped limiting piece 70, and the transportation bracket 300 is connected with the robot body 200 through the L-shaped limiting piece 70 and the top plate 220.

In an operation process, when the driving device 40 needs to be charged, a worker removes the driving device 40 from the first housing 10, places the driving device 40 on the transferring rack, and transports the driving device 40 to the charging position by the robot body 200 through the transferring rack 300.

The workflow of the meal delivery robot 1000 in the present application is explained in detail as follows:

The user places orders through the ordering application software, and the application software background generates order information according to the ordering condition of the user and sends the order information to the ordering application software of the caterer. The order information comprises meal conditions, meal ordering persons, meal placing unit identifiers and meal position identifiers. The meal preparing personnel prepares meals according to the order information of the users, and the order information is input into the meal delivery robot 1000 through the identification module 44 after the completion of the preparation of meals. For example, the caterer may align the electronic device with the identification module 44, and the identification module 44 identifies the two-dimensional code of the order information in the electronic device, thereby enabling entry of the order information into the meal delivery robot 1000. The meal delivery robot 1000 receives the order information, stores the order information, and determines a target meal delivery position according to the meal delivery unit identifier and the meal position identifier in the order information. The target meal placing position is a meal storage position of a user, the target meal placing position is determined by a target meal placing unit and a target meal position, the target meal placing unit is determined according to a meal placing unit identifier, and the target meal position is determined according to a meal position identifier. For example, the target meal position may be the 2 nd meal position in the meal unit numbered 15.

After determining the target meal placement position, the main control machine 47 controls the motor 48 corresponding to the meal placement unit identifier to rotate according to the meal placement unit identifier, and simultaneously controls the rotation angle of the motor 48 according to the meal placement unit identifier. When the motor 48 rotates, the first transmission gear 42 corresponding to the target meal placement unit is driven to rotate, and further, the first transmission gear 42 drives the second transmission gear 23 to rotate, so that the target meal placement unit is driven to rotate. When the target meal placement unit rotates to a position corresponding to the meal taking port 30, the main control computer 47 controls the target meal placement unit to stop rotating, so that the meal distribution personnel can place the meal on the target meal location.

After the meal is placed, the main control unit 47 controls the target meal placement unit to rotate, and when the shielding part 22 and the meal taking port 30 are determined to be at the corresponding positions, the target meal placement unit is controlled to stop rotating.

The robot body 200 performs path planning according to the meal delivery position in the order information, and conveys the box body 100 of the meal delivery robot to a preset meal delivery position according to the path planning result, and reaches the preset meal delivery position. When the user takes a meal, after the identification module 44 successfully identifies the user, the meal delivery robot 1000 repeats the meal placement process so that the user can complete the meal taking operation. After the meal is completed, the user returns the cutlery box via the return button 45.

In one embodiment, the user may be identified by swiping a meal card over identification module 44 or by scanning the order information two-dimensional code in the electronic device over identification module 44.

For example, when meal delivery robot 1000 delivers meals to a patient, the patient may be identified by swiping a patient card over identification module 44.

It is seen that the meal delivery robot 1000 of the present application supports remote contactless ordering while having functions of meal order recognition, automatic meal dispatch and meal box recycling.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art.
