Recent technological advances in utilization and generalization of Internet have overcome some of the limitations of remote robot control range and real-time monitoring system. However, It needs Embedded system with control protocol or hardware which has avility to port the micro realtime operating system in robot control system communicate with remote controlled robot, because those system use the wireless LAM or Bluetooth as a network media. In this paper, we design and implement the wireless MODEM protocol and install it to the server system. Also, we implement a client system could control the remote robot through the server and we assure that this protocol and client/server system ate suitable for small size remote control system based on Internet.
