A scheme of transmission system in micro robotics based on combined information data

摘要

Traditional inspection robots which equipped with analog camera normally have two channels to transmit image information and control signal. However, this double-channel method causes difficulties in miniaturization of robots. In this paper, we proposed a new scheme in which WIFI technology is utilized to intergrate images information and control signal to diminish the size of the module into 4*3cm~2. In order to realize the miniaturization, a RT5350 router is selected as the main controller. Through the establishment of a wireless local area network (WLAN), the mixed data (including frame image and the maximum 4KB control information) eventually reach the transmission rate of 15-30 fps. The scheme proposed in this paper can be implemented in a variety of situations, such as indoor mobile monitoring, micro land investigation, micro air vehicle, etc. Up to now, this scheme has been implemented and validated in miniature detecting robot. Experiments show that the transmission of image information is smooth and stable and the control signal is accurate and reliable.
