Special Issue on Visual Servoing and its Applications
Submission Date: 2019-10-15

Visual servoing task is to control the pose of a robotic system, relative to a target, using visual features extracted from an image. Advanced robot systems often integrate up-to-date sensors, vision systems, and visual servoing techniques to deal with non-static target objects of various shapes and colors. The environment a robot is immersed in its orientation, and its motion can be described through visual information. The camera may be carried by the robot or fixed in the surroundings, known as endpoint closed-loop (eye-in-hand) and endpoint open-loop, respectively. Visual servoing has proven to be useful in a wide range of real-world applications, such as military, medical devices, trade, search and rescue, security, among many others. For instance, visual servoing techniques can be applied on unmanned vehicles, which can be used for surveillance, road-traffic control, border inspection, and reserved areas supervision, to provide visual information from the surroundings. Nowadays, the study on enhancing the autonomy of these vehicles has focused on navigation and formation control, target recognition, and tracking, among many others, by improving their visual capabilities. For example, the formation control in unmanned aerial vehicle (UAV) swarms is used in applications like searching and mapping to fly in groups above vast areas for goods delivery, tracking and even locating and following military targets. Visual servoing must produces the necessary commands to maintain the vehicle attitude and define the flight path based on the provided information from onboard sensors. Improving the autonomy of robots is still one of the challenges facing visual servoing and there are various ongoing studies in this field, where each system may differ from others in size, appearance, type of power plant, and more; due to these differences, they may also show distinct characteristics, but the equipment employed for evaluating their position and orientation is usually the same, which consists of inertial measurement units (IMU) and vison sensors. One of the flaws of using inertial information for motion is the accumulation of small errors on estimating the robot position, which consequently results in drift and deviation in determining its location over time. In modern motion equipment, the global positioning system (GPS) information is used for continuously correcting the IMU estimations and solving this problem, but in the event of interference or disconnection of the GPS signal, the position and motion error should remain and therefore visual servoing can be used for guidance and navigation in different kind of applications to improve the robot autonomy by feedback control of pose and motion through information acquired by onboard vision sensors. Topics: The topics of interest, listed below, are aimed to show continuing efforts provided in the domain of Visual Serevoing applications. § Control system design for camera-carrying moving platforms. § Image processing algorithms for feature extraction. § Stability improvement. § Target location and recognition. § Speed estimation § Tracking

Special Issue on Internet of Energy - designing and planning energy-efficient smart control systems
Submission Date: 2019-12-31

The extensive attention drawn towards development of Internet and shift towards green energy, pioneered the novel concept of Internet of Energy (IoE) by converging the two notions with the aid of Internet of Things (IoT). IoT enables innovative ways to share data, leverage devices, and facilitates remote access. However, problems arise because the infrastructure has not been modernized for implementation. To capitalize on the notion of IoE, physical grids must evolve. The upgrading and automation of electricity infrastructures allow clean energy production with minimal waste. Millions of small renewable energy- generating units are added to the main energy system, in order to achieve maximum efficacy. Increasing demand for a clean energy intensifies the need of transforming the conventional grids. Even though the solution is renewable energy, the radical shift from existing grids leaves us with tremendous technical challenges that require an entirely new way of managing energy systems. In similar fashion, IoE benefits its stakeholders by increasing efficiency, wireless charging, saving money, and reducing waste production. Further, IoE uses sensors to gather data from various equipment to improve the operational performance, subsequently followed by analysis through domain-specific software. The beauty of IoE is that its benefits are not limited to the large manufacturers, but utility providers, domestic producers, and solar-based companies can also benefit from it. Furthermore, IoE also enables the grid infrastructure to improve energy generation and distribution, while facilitating the integration of renewable energy generators. Simultaneously, IoE ensures grid data collection from the beginning to the very last end of the grid. Such aggregated data will empower utility decision making regarding load balancing, forecasting, and pricing. For this special section we are soliciting high quality unpublished manuscripts that present original results. The aim is to bring novel research ideas, highlight the open issues, and indicate current research advancements and future directions in the field of IoE-based smart control systems and energy grids, their architectures and various applications in IoT.
