In order to realize precise positioning with remote observation and control of the food delivery robot in the room, this study designs a indoor robot positioning information system based on the DW1000 module and the network module of ESP8266. The improved TWR algorithm is used in the system to avoid the problem of clock out of sync among the base stations and improve the clock offset error of the base stations. The simplified TOA algorithm makes the system locate quickly and accurately. At the same time, the wireless Ethernet module ESP8266 is used to transmit the position data and the status information to the remote server which is easy to view the real-time position state and control the robot movement. The system is an embedded wireless interconnection system, which can satisfy the indoor robot positioning and information transmission, and realize the remote control of the robot.
