ABSTRACT
Objective: To design a portable teleoperated rescue device for persons who fell into the sea. Methods: The function analysis of rescue device and the design of target properties were performed using the quality function deployment method by summarizing the advantages of existing marine rescuers, marine environment and airborne characteristics. The optimal triangle rescuer was selected from six conceptual design schemes. The simulated analysis of surface pressure distribution was carried out with STAR-CCM+ software. The deformation, stress and strain energy were analyzed with ANSYS Workbench software. The reliability analysis was performed with failure mode and effect analysis (FMEA). Results: The triangle rescue device met the requirements of STAR-CCM+ analysis and ANSYS Workbench analysis, and achieved low energy consumption and good agility. The possible causes of failure in reliability analysis were dealt with accordingly. Conclusion: The design of portable teleoperated marine rescue device has the characteristics of portability, strong maneuverability and high safety. It can provide great help for maritime rescue and has certain military, social and economic values.
ABSTRACT
Teleoperation had become one of the most prolific areas of research due to the great number of applications in which the remote operation paradigm can be applied. Teleoperation is made from several disciplines, areas or techniques, ranging from communications to systems control and from virtual reality to digital signal processing. Hence, individual advancements in these areas could be applied to developments in teleoperation systems. This article presents a compilation of important terms and concepts. It also presents a compilation of the state of the art in teleoperation systems, with special emphasis in telesurgery applications and related research studies in the area comprising image processing and cooperative robotics, which have been used to increase the effectiveness in telemedicine systems and to increase the quality of surgical procedures.
