Design Study Of Solar-Powered Logistics Robot

In recent years,logistics is the industry that has been driving the automation process relatively fast.Urban logistics and distribution business is a huge market,and the application of logistics robots in this field has attracted a lot of attention.Logistics robots can improve the efficiency of expedited operations in same-city logistics and courier operations in remote areas,shorten delivery time and costs,and improve the reliability and accuracy of delivery.Under the situation affected by epidemics,logistics robots can realize the distribution needs of contactless distribution,remote distribution and relief and disaster relief,providing safer and more reliable services to the society.However,traditional logistics robots have some limitations in some aspects,such as only relying on lithium batteries for power supply,inability to recharge automatically,short battery life,and low efficiency.In contrast,solar-powered logistics robots offer longer working hours and higher transport efficiency.Solar cells can be charged naturally using sunlight and do not require external power sources or charging equipment,enabling solar-powered logistics robots to work for long periods of time in outdoor environments,greatly improving efficiency.Moreover,the use of solar-powered logistics robots can also reduce the consumption of traditional fossil fuels,which has the characteristics of environmental protection and sustainability.In this paper,we design a small solar-powered logistics robot with flexible C ZTS thin-film solar cells with high deformation resistance,build the solar-powered logistics robot,successfully assemble the solar-powered logistics robot and debug its map building and path planning,power supply system,and intelligent access system.The results of the debugging are that all the systems can work properly,and the range can be extended by using solar panels.The main research content is as follows.1.In order to meet the structural requirements of a small solar-powered logistics robot,an automatic control system is designed to ensure the stability of the logistics robot.This automatic control system consists of four modules,which work together to ensure the stability of the logistics robot.2.The navigation algorithm of the solar logistics robot designed in this paper is studied,and the map building,global path planning and local path planning are tested respectively,so that the solar logistics robot can navigate automatically in the case of static and dynamic obstacles,and then can complete the task efficiently.3.Optimize the absorber layer of the flexible CZTS thin-film solar cell by controlling different preheating and annealing temperatures in the preparation of the absorber layer of the copper-zinc-tin-sulfur thin-film solar cell to prepare a suitable absorber layer material for the absorber layer,and power the solar logistics robot through a photovoltaic power generation system,and improve the solar energy absorption efficiency with an automatic unfolding and retracting system.4.The software and hardware design of the intelligent access system of the solar logistics robot.Finally simulate and solar logistics robot in different environments to verify the working performance of each system of the robot.
