A Selecting Robots Method Using Visible Light Communication

From the view of Industry 4.0, robots and machines like as automated guided vehicles and manufacturing robots are focused on in order to achieve factory automations which changings from mass production to variant variable production. Managing them are important task for workers. For this environment, remote control is required to manage these devices, however, it is often difficult to know the identification number of them. Therefore, we propose a selecting system where we can select the controlled target device by using visible light communication. The transmitter sends its own identification number by the visible light communication and transmits the control command using wireless communication like as Wi-Fi. At this time, the control command is transmitted by the broadcast communication to all the devices connected to the same network. The device selected by the visible light communication receives the identification number of its transmitter, and the device can execute the control command on Wi-Fi which has the same identification number in its packet. In order to evaluate the complexity of device selection, we have some experiments which measures the operation time to select devices with unknown identification number. From this experimental result, the proposed method is considered to be the easy-to-use remote controller with the least operation error.
