The name of the food delivery robot in the application is only that the food delivery robot can be used for delivering food, and the using function and the using scene of the food delivery robot are not limited in the way.

Fig. 1 to 3 show a food delivery robot in one embodiment of the present application, fig. 4 and 5 show another food delivery robot in another embodiment of the present application, and the food delivery robots in the two embodiments have different appearances, and particularly have different shapes of the upper body.

Referring to fig. 1 to 3 in combination, an embodiment of the present application provides a food delivery robot, including: the walking device comprises a chassis 10, an upper body 20 and a support member 30, wherein a walking device 40 is arranged at the bottom of the chassis 10; the upper body 20 is arranged above the chassis 10 at intervals; the support 30 connects the chassis 10 and the upper body 20, respectively, such that the chassis 10 and the upper body 20 have a gap S in the up-down direction. The support member 30 thus serves both as a coupling function and supports the upper body 20 such that the upper body 20 is spaced apart from the chassis 10 with a gap S in the up-down direction.

The support member 30 is fixed to one of the chassis 10 and the upper body 20 and detachably connected to the other. For example, the lower end of the support member 30 is fixed to the chassis 10, and the upper end of the support member 30 is detachably coupled to the upper body 20. Alternatively, the lower end of the supporting member 30 is detachably coupled to the chassis 10, and the upper end of the supporting member 30 is fixed to the upper body 20.

Further, the food delivery robot further comprises a positioning sensor 50, wherein the positioning sensor 50 is arranged in the gap S, and detects the obstacle or the target object outwards through the gap S.

In the embodiment of the present application, the meal delivery robot avoids the chassis 10 and the upper body 20 through the supporting member 30, and an effective space is left for the positioning sensor 50. After the positioning sensor 50 is installed in the gap S between the chassis 10 and the upper body 20, because the gap S between the chassis 10 and the upper body 20 only has the supporting piece 30, and the rest positions are not shielded, the shielding of the light emitted by the positioning sensor 50 and the light reflected by the target object by the supporting piece 30 is small and can be ignored almost, so that the food delivery robot can perform all-dimensional scanning through the positioning sensor, and can realize 360-degree obstacle avoidance, and the food delivery robot can effectively avoid the obstacles when moving forward and backward, moving left and right, namely all-dimensional movement. In addition, the supporting member 30 is detachably connected to one of the chassis 10 or the upper body 20, so that the versatility of the food delivery robot is improved, and the chassis 10 and the upper body 20 can be assembled with the upper body 20 and the chassis 10 of another model or function respectively after being detached.
