Automatic Rescue Rat Guiding System Based on Locational and Directional Information

The goal of this study is to develop an automatic rescue rat guiding system based on a new method utilize the locational and directional information. In this method, the rat reward system is stimulated with an implanted electrode so that stimulus frequency increases as the rat turns its body axis toward the destination. We develop a “back pack” for rats, which is equipped with a GPS module, digital compass, micro electrical stimulator and PIC microprocessor to integrate sensor information and decide stimulate conditions. As a result we were successful in navigating rats to the destination accurately in short time in the indoor field.
