Abstract:With the increasing popularity of mobile devices and the development of web technology,mobile devices become more popular than computer as the Internet terminal.We need to use responsive design to achieve the perfect layout&visual effect for any type of device for web content.By combining the new features of HTML5 and CSS3,and by preventing the mobile browser and adjusting the page size automatically and media query and using flow layout technologies,responsive web design is effective in fitting different users that use different terminals.

Abstract:An intelligent sorting and conveying robot is designed in this paper in order to simulate the operation procedure of the automatical logistics system. STM32F103 chip microcomputer is adopted as the core control module. Other hardware modules include the power supply module,the motor driver module,the gray sensor module,the color recognition module and so on. In the software design,some key algorithms controlling the robot are considered such as the robot’s motion control algorithm,the color recognition algorithm and the ground gray detection algorithm and etc. At the same time,the robot’s moving lines and its concrete sorting and conveying function are also planned. Test results show that the designed intelligent robot can realize well the appointed object’s sorting and conveying,and it has certain applicable significance.
