In this study, we describe a palm-sized robotic fish that can automatically track a goldfish. A robotic fish is suitable for ecological surveys because it is difficult to be noticed by aquatic animals. However, so far, there is no palm-sized robotic fish that can automatically track an aquatic animal. Automatic tracking by the robot is carried out by recognizing the goldfish with a camera and changing the swimming direction towards the goldfish. To follow the agile movement of the goldfish, the robot has a high turning ability with multiple joints. Finally, we have confirmed the robot can track a goldfish.
