Design Study Of Intelligent Catering Service Robot

Combining with intelligent robot technology and a series of new generation of information technologies including internet,the electrical and electronic technology and cloud computing,intelligent robots will play an increasingly important role in the fields of industry,services and military affairs.Because of the emergence of some social problems,such as the rapid development of robot technology,the improvement of people's living standards and the population aging,there is a growing demand for service robots.The use of catering service robots in China is still at the beginning.Due to the imperfect production technology and other reasons,the price is expensive,and the function is single,not to mention widely achieving.In this paper,the mechanical structure of the main part of the restaurant service robot is selected and designed briefly,and part of the content is calculated and checked.The control system uses STM32F103ZET6 as the master chip.It has many advantages,such as high reliability,rich interface,low power consumption and excellent real-time performance.The development of official firmware library can reduce the difficulty of development and greatly shorten the development cycle.The design of embedded control system mainly includes two parts: hardware design and software design.The hardware part mainly includes driver module,wireless communication module,speech recognition module,ultrasonic detection module,handwriting recognition and TFTLCD display module.The type of each control module is selected,the working principle of the module is briefly described,and the circuit diagram of each module is drawn.Software design is mainly based on the keil5 environment,using official firmware library development,and a real-time μC/OS-III system is also transplanted,which improves the real-time,stability and maintainability of the system.At the same time,make the later control function expand and perfect more convenient.The path planning of mobile robot is one of the core technologies.The purpose is to find a path from the initial position to the target position under the requirements of environmental conditions and performance indicators,which can avoid all obstacles and have the shortest length.In this paper,on the basis of the traditional ant colony algorithmto make improvements,the disadvantages of the traditional ant colony algorithm are improved to a great extent,including long search time and redundant path.At the same time,the feasibility of the algorithm is analyzed and authenticated by MATLAB software.Real time positioning in robot working process using UWB technology,TOA method is used to locate.Improving the accuracy of time delay estimation by MUSIC algorithm.Finally,the accuracy of the positioning is improved with Kalman filter.
