Remote actuator control method by visual feedback using ROI with communication property of multiple channels

Many types of sensors and actuators are being connected to networks, and highly functioning or highly efficient services that use them are being investigated. One useful application of such systems might be remotely controlling actuators by using visual feedback. This method would be used to capture images of actuators and transmit those images to highperformance computers via networks for fast image analysis for obtaining information related to the actuators' state, e.g., velocity and position. This method allows the separating of sensors, computing resources, and actuators. Thus, actuators can be easily fabricated and at a low cost. However, delay and loss of data in networks are possible, which negatively affect performance. Therefore, we propose a communication method that transmits only control data and small images sufficient for controlling actuators via stable networks for less cost and more flexible system design.
