Courses on the motion and operation of remotely operated vehicles (ROV) tend to feature abstract theoretical concepts, numerous formulas, combinations of mathematical and physical concepts and teaching that is disconnected from practice. As with the development of computer technology, the dynamic connection between the combination of the highly-realistic visual effects of simulation and theoretical classroom teaching has the aesthetic characteristics of a physical science. In this study, a virtual teaching platform for ROVs was developed on the basis of current virtual simulation technologies, as well as the needs of courses focused on ROV motion and operation. Based on detailed analyses of the functional and performance requirements of a virtual teaching platform for ROVs, the system was subdivided into six subsystems: remote-control simulation, dynamic and kinematic mathematical modeling, underwater operation tools simulation, visual scene display, teacher control and network administration, using an object-oriented design method featuring modularization and standardization. The subsystems facilitate modular development, integration and function extension, and support the openness, inheritance and reusability of the system. The platform is used to intuitively acquaint students with ROVs’ kinetic characteristics and operating methods by means of intuitive 3D models, precise motion calculation, and real operating scenes. Based on teaching practice in colleges and universities, a typical work-task-oriented practical teaching system was developed, along with the application of course design and scenario design for the ROV virtual teaching platform. Through interactive operation, students can dynamically and intuitively observe the motion of ROVs during navigation, helping them to learn about hydrodynamic performance. With simulated ROV operation, students learn about the principles of dynamic mechanical tools as well as the relationships between the interaction forces of ROVs. This contributes to disciplinary progress in naval architecture and ocean engineering, as well as the development of students’ practical engineering competence.

We introduce the Lee Sang Gak Telescope (LSGT), a remotely operated, robotic 0.43-meter telescope. The telescope was installed at the Siding Spring Observatory, Australia, in 2014 October, to secure regular and exclusive access to the dark sky and excellent atmospheric conditions in the southern hemisphere from the Seoul National University (SNU) campus. Here, we describe the LSGT system and its performance, present example images from early observations, and discuss a future plan to upgrade the system. The use of the telescope includes (i) long-term monitoring observations of nearby galaxies, active galactic nuclei, and supernovae; (ii) rapid follow-up observations of transients such as gamma-ray bursts and gravitational wave sources; and (iii) observations for educational activities at SNU. Based on observations performed so far, we nd that the telescope is capable of providing images to a depth of R = 21:5 mag (point source detection) at 5- with 15 min total integration time under good observing conditions.

Recently, although the need of marine robots being raised in extreme areas, the basis is very deficient. Fortunately, as the robot competition is vitalizing and the need of the robot education is increasing, it is desirable to establish the basis of the R&D and industrialization of marine robots and to train professionals through the development and diffusion of marine robot kits. However, in conventional case, there is no remotely operated aerial robot‐kit based on the balloon for the marine robot competition, which has the abilities of the airborne locomotion and obstacle avoidance. To solve this problem, an aerial robot‐kit which has the abilities of the airborne locomotion and remote control, is developed. To verify the performance of the developed kit, test and evaluation such as surge, yaw and pitch is performed. The test and evaluation results show that the possibility of the real applications of the developed kit.
