Abstract：In this paper, an indoor mobile robot system with autonomous wireless charging function is developed and magnetically coupled resonance technology is used to perform non-contact wireless charging for the robot. The transmitting coil is fixed somewhere in the floor and a speaker is placed in the same area, while the receiving coil is placed in the robot bottom. The charging steps are as follows: Firstly, robot will carry out the charging procedure if the monitored battery voltage is lower than the threshold value or user sends a mobile phone short message to the robot. Simultaneously, voice playback unit of the power emission source is triggered so that it will broadcast voice instruction and call robot charging. Secondly, robot processes the sampled voice signals and determines the source direction using the sound localization algorithm on DSP. What’s more, the robot is driven and controlled by DSP which guide its search for the power emission source. Finally, wireless charging can be achieved when robot enters within the designated area of the emission source. Since the system has the characteristics of autonomous mobile tracing and non-contact wireless charging, the robot can quickly find the power supply in tens of seconds as well as intelligently realize the wireless charging without human intervention.
