色情報に基づく小型魚ロボットFOCUSの目標物追従制御

It is necessary for a small aqua robot to search for a target in order to investigate creatures such as fishes in a river or lake. However, control signals by electric wave from outside do not reach a robot easily in water. Therefore, aqua robots must search the target autonomously without signals from outside. It is important for a robot to gaze forward and recognize the target in water. In this study, we have used a fish robot named FOCUS which can swim in water by using the tail fin. This robot has some micro CMOS cameras and a FPGA circuit board for data processing. A red object is detected with the CMOS camera. In addition, FPGA calculates where the red object is located in the image. This robot controls the tail fin mechanism and submersible system in order to decide the course of the robot in response to the calculated positional coordinates. We have confirmed that this robot can recognize a color target and follow the target in water.
