도우미로봇은 혼자 힘으로 걷기 어려운 노약자를 보조하는 보행 보조 기능과 다양한 오락 기능을 수행하는 로봇이다. 이 로봇은 음원 위치 추정기법에 의해서 어느 방향에서 소리가 발생하였는지 알아내고 그 방향으로 머리를 회전한다. 로봇의 머리에는 CCD카메라가 장착되어 있어서 카메라로부터 들어오는 영상에서 사람의 얼굴을 찾고 그 사람이 있는 곳까지 자율 주행기능에 의해서 장애물을 회피하며 이동한다. 사용자의 앞까지 이동하면 로봇은 이동을 멈추고 사용자로부터 명령을 받을 때까지 대기한다. 노약자는 로봇의 전반부에 부착되어 있는 터치스크린을 이용하여 로봇에게 다양한 명령을 내릴 수 있다. 로봇은 명령에 따라 보행 보조 작업을 수행하거나 전자메일, 음악, 영화 등 다양한 엔터테인먼트 서비스를 수행하게 된다.

As society becomes more complex and advanced, the risk of accidents is inevitably increased, and this is an opportunity to increase the occurrence of not only congenital disabilities but also acquired disabilities. In this situation, the use of rehabilitation robots, a complex of advanced technologies, is expected to increase steadily in the future. So the authors would take a look the technological trends and future development prospects of domestic and foreign rehabilitation robots. Until now, disability assistive robot technology has been mainly developed in the field of supporting disability with walking disabilities or work limitations rather than cognitive disabilities. However, another issue of population aging is that cognitive impairment has the potential to increase, so development of a disability assistance robot that secures user safety must be actively promoted. It is thought that empirical results should be derived and converged

This study is a review study attempted to analyze the current situation of surgical robots based on previous research on surgical robots in the era of the 4th revolution, and to forecast the future direction of surgical robots. Surgical robots have made full progress since the launch of the da Vinci and the surgical robot is playing a role of supporting the surgeries of the surgeons or the master-slave method reflecting the intention of the surgeons. Recently, technologies are being developed to combine artificial intelligence and big data with surgical robots, and to commercialize a universal platform rather than a platform dedicated to surgery. Moreover, technologies for automating surgical robots are being developed by generating 3D image data based on diagnostic image data, providing real-time images, and integrating image data into one system. For the development of surgical robots, cooperation with clinicians and engineers, safety management of surgical robot, and institutional support for the use of surgical robots will be required.

Recently, ere are many researches to improve the quality of e medical service such as Point of care (POC). To improve the quality of the medical service, not only good medical device but also more man power is required. Especially, the number of nurses are very few in Korea that is almost the lowest rank compared to OECD countries. If the simple repetition works of the nurse could be removed, it is possible to use the skillful nurse for other works and provide better quality services. There are many simple repetition works which the nurses have to do, such as replacing the ringer's solution. To replace the ringer's solution automatically, it is necessary to detect residual quantity of the ringer's solution. In this paper, image processing is used to detect the residual quantity of ringer's solution, and modified self quotient image (SQI) algorithm is used to strong background lights. After modified SQI algorithm, the simple histogram accumulation is done to find the residual quantity of the ringer's solution. The implemented algorithm could be use to replace the ringer's solution automatically or alarm to the nurses to replace the solution.

Recently, various motion beds have been actively developed and popularized. The motion bed has the functions of height adjustment, back plate rising, knee lifting, tilt function and left / right rotation, and the remote control can conveniently be used by the patient himself or the caregiver to move the patient. However, since the medical bed for use does not have a function of preventing pressure ulcers, exchanging sheets, and transferring patients, it is necessary to disperse body pressure by using a pressure ulcer prevention matrix to prevent pressure ulcers. However, it is accompanied by muscle strength and hard work, and nurses are avoiding difficult nursing care. In this study, we developed the first prototype in the world and confirmed that the system works normally with the goal of developing multifunctional beds that automatically perform the prevention of bed sores, the exchange of sheets and the transfer of patients in order to facilitate such nursing work. It is anticipated that the proposed multifunctional motorized bed in the future will be a model of a medical robot for smart healthcare.
