Description

Domestic transport robot with intelligence lift platform

Technical Field

The invention belongs to the technical field of intelligent robots, and relates to a household transport robot with an intelligent lifting platform.

Background

At present, with the progress of science and technology, the concept of smart home is developed, and people are more and more pursuing an intelligent life style, along with a series of smart home devices: smart televisions, smart air conditioners, smart refrigerators and other concepts and products emerge, and in the life of home, people are used to the lazy and agreeable life, but often need to take and deliver some articles at home, so can we not help us accomplish these tasks with smart robots?

Then in our conception it should have the function:

1: it has the function of moving at home.

2: it has the function of avoiding obstacles.

3: the video camera has the functions of a camera and networking, and can transmit shot real-time video information to an upper computer.

4: it possesses lift platform, can go up and down with the article of transportation, when conveniently people got and put article and reduce during the rise, can be that the robot keeps lower focus, convenient transportation.

In summary, the problems of the prior art are as follows:

present domestic intelligent transportation robot all is comparatively heavy, lacks the platform that can intelligent control article go up and down for in the transportation, can't reduce the whole focus of robot, appear empting the problem easily.

The difficulty of solving the technical problems is as follows: the difficulty of solving this problem lies in designing intelligent gravity perception platform, whether have put article on the intelligent perception platform, can descend automatically when the pressure of perception article, when the perception article is taken away, can rise automatically.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention provides the household transportation robot with the intelligent lifting platform, so that the household life is more intelligent, convenient, interesting and pleasant.

The technical scheme is as follows:

a household transport robot with an intelligent lifting platform comprises an ultrasonic obstacle avoidance module 13, a camera 14, a lifting platform, a trolley chassis, a control chip 8 and a WiFi communication module 11;

the ultrasonic obstacle avoidance module 13 is used for detecting whether an obstacle exists in the front of the trolley and transmitting distance data to the control chip;

the camera 14 is used for transmitting the shot content to the control chip in real time through the USB interface;

the trolley chassis consists of a trolley bottom plate, a driving motor and a driving wheel 12;

the control chip 8 is used for controlling the forward and reverse rotation of the four driving motors to realize the forward, backward, left-turn and right-turn actions of the chassis, reading the data of the ultrasonic module, the numerical value of the film pressure sensor, the state value of the travel switch and the data of the camera, transmitting the data to the notebook computer, controlling the movement of the trolley and controlling the lifting of the lifting platform;

the WiFi communication module 11 is used for realizing communication between the control chip and the notebook computer.

Further, the lifting platform comprises a top fixing ring 1, a conveying belt 2, a lifting motor 15, a first travel switch 3, a second travel switch 10, an optical axis 4, a film pressure sensor 16, a linear bearing 7, a tray 5, a lifting platform 6 and a control chip 8.

Further, the ultrasonic obstacle avoidance module 13 is used for detecting whether an obstacle exists in the front 15 cm of the trolley.

Further, the ultrasonic obstacle avoidance module adopts an HC-SR04 module.

Further, the pressure sensor employs a flexible membrane pressure sensor FSR 402.

Further, the WiFi communication module adopts ATK-ESP 8266.

Further, the control chip adopts Arduino nano.

The invention has the beneficial effects that:

the household transport robot with the intelligent lifting platform can intelligently sense whether articles are placed on the platform, can automatically fall when sensing the pressure of the articles, and can automatically rise when sensing that the articles are taken away.
