| With the development of robot control technology and Internet technology, robot’remotecontrol throw internet has become a new way to control robot. At present, the domestic researchof mobile robot’s remote control technology based on network has made a lot of results.Althoughrealizing remote control of mobile robot, the control flexibility is insufficient. Therefore, in olderto improve the flexibility, this paper holds Android-based mobile smartterminal and mobile robottogether. Designs and develops a remote control system for a mobile robot based on the Android.Firstly, This paper describes the design concept of the Android-based mobile robotremote control system. That is using Android-based mobile smart terminal to control mobilerobot remotely through WLAN. Then this paper analyzes the structure and control principle ofthis remote control system which contains a server-side on mobile robot and a client-side onAndroid platform. The server sends video gathered by mobile robot’s camera to the client whichaccepts the video and displays it to user. The user controls the mobile robot remotely only by thevideo.Secondly, according to the design scheme, we developed an Android-based mobile robotremote control system. In detail, we realized videotransmission between server and client usingJMF(Java Media Framework) and Socket programming. Also realized bottom control of mobilerobot by Java program through JNI(Java Native Interface). During the development process, westudied the two kind of control schemes, and compared with each other.Lastly, in order to verify the feasibility of Android-based mobile robot remote controlsystem, the system was tested after the system developed. Firstly, the network transmissionreal-time test is done for the video transmission between server and client. Test results show thatthe video transmission real-time through WLAN between server and client is well. Then theentire system is measured. In a decorated obstacle avoidance area, user controls the robot tomove and to avoid obstacles in the field remotely through the Android tablets. The test resultindicate that the Android-based mobile robot remote control system in this paper basically meetthe requirements of remote control. The flexibility and continuity of control is well. The serverand client application are user-friendly, and easy to operate. It can be used as the rudiment of the Android-based mobile robot remote control system. |
