The robot control by PC through the wireless communication between the PC and the single-chip microcomputer not only expands the functions of the PC, but also creates more functions of the indoor service robot. Therefore utilization of the wireless communication between the PC and the robot can make full use of resources and improve the efficiency. The hardware of the indoor service robot includes the hardware of the robot control system and the hardware of the PC monitor system. The software of the indoor service robot consists of the software of the PC control software and the single-chip microcomputer control software. Therefore, the robot can autonomously walk along the track or walk under the manual control even when the robot is a long distance away.
