[0043] Preferably, in order to increase the contact area between the tray 103 and the support platform 102 and ensure the stability of the installation, the tray 103 can adopt a large-area slot structure to be detachably connected to the support platform 102. The tray 103 is buckled into the support platform through the slot, which can effectively ensure that there are multiple connection points between the tray 103 and the support platform 102, thereby increasing stability.

[0044] The present application adopts a separate design for the tray 103 and the support platform 102, so that the tray 103 can be taken out and used independently, and the tray 103 can also be connected to the support platform 102 by a locking mechanism, which increases practicality.

[0045] The tray may be made of plastic or metal, and the specific material is not limited in this application.

[0046] Of course, as another optional embodiment, the tray 103 may also be magnetically connected to the support platform 102. Specifically, the tray is made of metal, and a magnetic component is disposed inside the support platform.

[0047] Further, in order to facilitate taking the tray 103, as Figure 1 As shown, the edge of the tray 103 may also include a convex surface, which serves as a side surface of the tray 103.

[0048] In one embodiment, the tray 103 may be a rectangular tray 103, one side of which is detachably connected to the support platform 102 of the robot via a slot structure, and the edges of the other sides of the rectangular tray 103 include convex surfaces, which serve as the side surfaces of the tray 103. It is understood that the height of the side surface of the tray 103 may be designed to be convenient for taking, and this application does not limit this.

[0049] like Figure 1 As shown, the side of the tray 103 can be in an outwardly turned-up state, which makes it easier for the user to remove and install the tray 103 from the support platform 102. In addition, in order to facilitate the placement of long objects, a notch 104 is provided on one side of the tray 103. The height of the side at the notch 104 is lower than the height of the side at the non-notch 104.

[0050] In one embodiment, a notch 104 is provided on one side of the tray 103, and a long object such as a long chopstick or a straw can be placed horizontally to the robot, for example, the notch 104 is located close to the robot. It is understandable that the size of the notch 104 and the side height of the notch 104 can be designed according to actual needs, and this application does not limit this.

[0051] Furthermore, the tray 103 may further include a circular sink 105 on the plate surface for placing water cups to maintain the stability of the water cups during transportation and prevent them from moving or spilling. It is understandable that the diameter of the circular sink 105 may be designed according to the size of a general water cup, and this application does not limit this.

[0052] Of course, as other optional embodiments, the tray 103 may also include sinks of other shapes on the disk surface, such as square, oval, etc.

[0053] Preferably, the operation screen 101 can be arranged on the first side of the robot, and the support platform 102 is integrally arranged on the first side of the robot, and the first side is the front of the robot; the vertical height between the support platform 102 and the bottom of the robot is less than the vertical height between the operation screen 101 and the bottom of the robot. By arranging the support platform 102 on the front of the robot and below the operation screen 101, it is more ergonomic and convenient for users to operate.

[0054] It is understandable that the support platform 102 can be set at the middle area of ​​the robot, wherein the middle area of ​​the robot can be regarded as the middle area, so as to be more convenient for users in standing and sitting positions to pick up items. For example, the support platform 102 can be set at 2 / 3 of the height of the robot.

[0055] In actual application scenarios, the robot ordering and delivering meals is done by the elderly using the ordering system on the interactive screen to order and deliver meals. After the interface determines the elderly's meals, it will automatically place an order to the meal preparation area. The robot automatically goes to the meal preparation area according to the route, and the staff places the meal on the tray 103 in front of the robot and delivers it to the elderly's dining table to complete the service. Of course, the elderly can also choose to place the meal on the robot's tray 103 after the meal is prepared at the meal preparation area, and the robot will deliver it to the dining area. In addition to delivering meals, other daily necessities can also be delivered by the robot, such as helping the elderly to deliver clothes, daily toiletries, and medicines to be taken on time in the bedroom space of a community nursing home.

[0056] Furthermore, in order to store items and deliver multiple items at one time, the robot may further include: a first drawer 106, which is embedded in the second side of the robot.
