| In recent years, with the rapid development of modern information technology, wireless communication technology has become an indispensable part of people’s life and work, including daily use cell phones, wireless devices, etc. The 4 g and WIFI are the most popular wireless communication technology in the 21st century. And China now has the world’s largest mobile phone user base, make good use of the Android smartphone portability is strong this characteristic, combined with a broader range of 4 g mobile networks, remote control of home robots will look for China’s huge wireless communication market provides an excellent opportunity. And the improvement of industrial automation degree, industrial site of a lot of flammable, explosive contour endanger the heavy manual labor is an urgent need to replace manual laborers by robots. On the one hand, can ensure the safety of workers’ labor, on the other hand can greatly improve the labor productivity. Therefore, the combination of wireless communication to the robot’s remote wireless control mode, has become the new direction of the robot research.This paper discusses the realization of remote wireless control a 14 degrees of freedom wheeled robot system, the Android and PC two platforms to complete basic walking, fetch operation and video monitoring task. Purpose is to grasp the robot wireless control principle and mechanism, for more and more popular in the wireless control field has a strong applicability and importance, plays an important role in promoting the development of robots. Work as follows, mainly mobile phone connected wi-fi access to modified the mini router, open to write good Android software, through the interface button to remote driving intelligent robot, control panel outside connection server through a router, modification of the mini router will be from the mobile terminal to receive wireless signals via a serial port to the control panel, control surface at the bottom of the motor to drive, complete the robot’s movement before and after, steering operation so as to realize the order reach the designated position; And through the steering gear, the rotation of the stepper motor drive arm, complete the fetch action. And you can also through the camera back to the video information, the realization of remote data collection.Conclusion was that, with the comprehensive coverage of 4 g technology, any time any place, as long as we are able to connect to the Internet, remote control we need to control equipment becomes possible. This is the communication technology of the next generation of technology of Internet of things simple model, simple and convenient, and the application range is wide. Will bring great convenience to our production life. |
