To reduce the radar cross section at microwave frequencies, it is necessary to implement electromagnetic (EM) absorbing devices/materials to decrease the strength of reflected waves. In addition, EM absorbers also find their applications at higher spectrum such as THz and optical frequencies. As an atomic-thick two-dimensional (2D) material, graphene has been widely used in the development of EM devices. The conductivity of graphene can be electrostatically or chemically tuned from microwave to optical light frequencies, enabling the design of reconfigurable graphene EM absorbers. Meanwhile, the derivatives of graphene such as reduced graphene oxide (rGO) also demonstrate excellent wave absorbing properties when mixed with other materials. In this article, the research progress of graphene and its derivatives based EM absorbers are introduced and the future development of graphene EM absorbing devices are also discussed.

Abstract Visual SLAM (Simultaneously Localization and Mapping) is a solution to achieve localization and mapping of robots simultaneously. Significant achievements have been made during the past decades, geography-based methods are becoming more and more successful in dealing with static environments. However, they still cannot handle a challenging environment. With the great achievements of deep learning methods in the field of computer vision, there is a trend of applying deep learning methods to visual SLAM. In this paper, the latest research progress of deep learning applied to the field of visual SLAM is reviewed. The outstanding research results of deep learning visual odometry and deep learning loop closure detect are summarized. Finally, future development directions of visual SLAM based on deep learning is prospected.

Background: Modular self-reconfigurable robot is a hot topic in current robotics research, the modular self-reconfigurable robot is composed of several modules with certain autonomous ability and perceptual ability. Through mutual docking and assembly, the overall configuration is changed to achieve different moves and operation functions. Compared with the traditional robot, it has strong adaptability to the environment and the ability to deal with changeable tasks. Objective: The recent modular self-reconfigurable robot is summarized, and its structure, characteristics and development are introduced. Methods: This paper summarizes the patents and research progress of modular self-reconfigurable robot, and introduces the current development of modular self-reconfigurable robot from the aspects of structure features, docking methods, driving types and applications. Results: This paper classifies the structural features, docking methods and driving types of various modular self-reconfigurable robots, summarizes the typical features, and discusses the current and future development of modular self-reconfigurable robots. Conclusion: Modular self-reconfigurable robot is a new subject in the field of robotics research in recent years. Through the docking among a large number of unit modules which changes the overall configuration, extends the motion form and realizes different motion gait, modular self-reconfigurable robot can replace traditional robot to complete the work in a complex environment, which is of great significance to the development of robot. Therefore, more modular self-reconfigurable robot patents should be invented.
