An intelligent food delivery system based on drones

Abstract

The invention belongs to the technical field of unmanned aerial vehicle application, in particular to an intelligent feeding system based on the unmanned aerial vehicle, comprising an unmanned aerialvehicle, a controller, a shock absorbing module, a mounting plate, a support plate, a dual-axis motor, a ball screw, a slider, a polishing rod and a claw. The two rotating shafts of the dual-axis motor are fixedly connected with the ends of two ball screws with different rotation directions. A low end of that slider is slidably connected with the polished rod, and an upper end of the slider is connected with a ball screw through a screw nut pair; An upper end of an connection jaw is fixed at the low end of the slider; The clamping jaw is used for clamping the meal plate, and the clamping jaw is used for clamping the meal plate. A set of shock absorbing sleeves is arranged between the bottom plate and the mounting plate of the unmanned aerial vehicle (UAV), and a spring is arranged in the central hole of the shock absorbing sleeves, so that the shaking of the UAV during flight is avoided and transmitted to the mounting plate, and the food in the meal plate is further prevented from spilling in the transportation process. Driving the ball screw with different rotating directions by the two-axis motor can realize the stable clamping of the clamping jaws to the dinner plate.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and specifically relates to an intelligent meal delivery system based on unmanned aerial vehicles. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle" ("UAV"), is an unmanned aircraft controlled by radio remote control equipment and its own program control device. [0003] In recent years, countries have increased research and development and investment in drones, greatly improving the technology and performance of drones, and expanding the scope of use of drones. Drones can be used to take selfies, deliver goods, and For aerial photography and delivery, but these are all outdoors, and indoor applications are relatively rare. At present, some restaurants use drones to deliver food. These special waiters fly under the control of the infrared sensor system installed in the restaurant. The set flight path flies over the heads of customers to de...

AI Technical Summary

Problems solved by technology

[0004] However, the existing food delivery drones have some problems while providing convenience. If the customer picks up the meal slowly, the drone needs to stay in the air for a long time in front of the dining table, and cannot wait for the customer to pick up the meal in the shutdown state. Causes great inconvenience: On the one hand, it consumes power. In order to meet the requirements of carrying food, the food delivery drone needs to reduce its own weight. Generally, the battery capacity of the design is relatively small, and the waste of power will increase the charging times of the drone and reduce the Utilization rate of drones; on the other hand, when the drone is flying in the air, the flying height is parallel to the dining table, which is relatively low. The restaurant has a relatively large flow of people, and the blades are easy to hurt customers. Moreover, the airflow generated by the blades will affect customers’ dining experience. Feel and experience; moreover, when the customer picks up the meal, the weight of the drone and the center of gravity suddenly change, which may cause the flight status of the drone to be unstable and cause food to spill
