A decrease in the birthrate and aging are progressing in Japan and several countries. In that society, it is important that physically weak persons such as elderly persons are able to take care of themselves. We have been developing exoskeletal robots for human (especially for physically weak persons) motion support. In this study, the controller controls the angular position and impedance of the exoskeltal robot system using multiple fuzzy-neuro controllers based on biological signals that reflect the human subject's intention. Skin surface electromyogram (EMG) signals and the generated wrist force by the human subject during the elbow motion have been used as input information of the controller. Since the activation level of working muscles tends to vary in accordance with the flexion angle of elbow, multiple fuzzy-neuro controllers are applied in the proposed method. The multiple fuzzy-neuro controllers are moderately switched in accordance with the elbow flexion angle. Because of the adaptation ability of the fuzzy-neuro controllers, the exoskeletal robot is flexible enough to deal with biological signal such as EMG. The experimental results show the effectiveness of the proposed controller.

According to the National Security Service of the National Police Agency, intrusion into empty houses increased form 2013 to 2016. Consequentially this statistics seemed that house intrusion, burglary is increasing. Also according to the statistics of Public Prosecutors'Office, a total 203,573 theft crimes occurered in 2016, of which 18.9% were theft after intruding. By reson of this is most frequent case of intrusion and theft, we have been studing the RodSecurityRobot model to enhance security in many factories to manage. In order to care for security to the high place, we have propsed a road guard robot model which controls the ground in cooperation with the robot that manages the ground by using the drones. The robot and the drone move together to autonomy to avoid objects. And they check time interval. they also goes to the charger to charge when there is no battery.

In this paper, a human coexistence-type companion robot that can communicate with people in daily life and alleviate the gap in care personnel was studied. Based on the voice recognition module, servo motor, and Arduino board, a companion robot equipped with a robot arm control function using voice recognition, a position movement function using RC cars, and a voice recognition function was tested and manufactured. As a result of the experiment, the speech recognition experiment according to distance showed the optimal recognition rate at a distance of 5 to 30 cm, and the speech recognition experiment according to gender showed a higher recognition rate in the first tone, monotonous tone. Through the evaluation results of these motion experiments, it was confirmed that a companion robot could be made.

This paper introduces a customized pet care and training system based on information technology. A specific animal is recognized by nose-print recognition. Pet robot induces the animal to move to trainer device. Trainer device trains the animal by snack, play, and clicker, and it can be easily extended for specific training using add-on devices. Pet band performs vital sign monitoring, prevention of home escape, and measurement of exercise amount. By changing configuration, this system can perform various training programs such as mitigation of separation anxiety, induction to defecation place, and prohibition of tresspassing specific place. It also provides customized training by analyzing individual behavior of animal. It can exercise and play the animal when owner is out, and it can immediately notice to the owner when the animal has health trouble.

Malignancy-associated mortality, decreased productivity, and spiritual, social and physical burden in cancer patients and their families impose heavy costs on communities. Therefore cancer prevention, early detection, rapid diagnosis and timely treatment are very important. Use of modern methods based on information technology in cancer can improve patient survival and increase patient and health care provider satisfaction. Robot technology is used in different areas of health care and applications in surgery have emerged affecting the cancer treatment domain. Computerized and robotic devices can offer enhanced dexterity by tremor abolition, motion scaling, high quality 3D vision for surgeons and decreased blood loss, significant reduction in narcotic use, and reduced hospital stay for patients. However, there are many challenges like lack of surgical community support, large size, high costs and absence of tactile and haptic feedback. A comprehensive view to identify all factors in different aspects such as technical, legal and ethical items that prevent robotic surgery adoption is thus very necessary. Also evidence must be presented to surgeons to achieve appropriate support from physicians. The aim of this review article is to survey applications, opportunities and barriers to this advanced technology in patients and surgeons as an approach to improve cancer care.

The purpose of this study is to find out how voice recognition technology can be utilized to solve the elderly problem rapidly aging in Korea. Public support services and civilian nursing services for the elderly are expected to expand in Korea. In this case, voice recognition technology can be used variously for the elderly who are not familiar with the media interface. To this end, our researchers visited Japan and examined the achievements obtained by voice recognition technology in the elderly care. Especially, when caregivers write reports, they have greatly reduced their working hours by replacing the handwritten reports with ones using voice recognition technology. This method can be easily implemented in Korea. In addition, the social cost of the elderly support can be gradually reduced through the development of a robot equipped with voice recognition technology. Consequently, we realize that when voice recognition technology is combined with artificial intelligence programs of various emotion recognition functions and various policy possibilities as well.

The purpose of this study was to explore the components of the geriatric robot pet, which might be helpful in caring for elderly people in the future. Focus group interview-with two focus groups-was performed between August 2014 and December 2014. Study participants were 13 geriatric experts from nursing, medicine, social work, and physical/occupational therapy. All interview data were transcribed, followed by debriefing and a qualitative content analysis. Three main themes emerged: acknowledgment of the usefulness of geriatric robot pet, establishment of elderly-centered appearance, and the functions of the robot pet to meet the needs of elders and family members. The robot pet was considered to be useful to elders who live alone since they can benefit from companionship and care provided by the robot pet. Geriatric robot pet needs to be manageable in size and weight, like a small dog. Moreover, a function that allows for interaction with and monitoring the elderly would be beneficial. The baseline elements that could guide further development of contents for the Korean geriatric robot pet were proposed from the results of FGI. Studies that validate these elements are necessary.

Objective : The purpose of this study was to look at a systematic review on the effects of robot-assisted therapy on stroke rehabilitation in upper limbs. Through this comprehensive study, we have to compare the studies. Methods : We systematically examined papers published in journal from June 2012 to September 2012, using EMBASE, MEDLINE, etc. 12 studies(randomized controlled trials) were included in the analyses. Results : Selected 12 studies were Pedro score 2 or more. The primary outcome measure tools including tools for upper extremity function and activities daily of living were used. Through various intervention, Robot-assisted therapy maximizes the effectiveness of intervention. The effects of upper extremity function and functional ability(ADL) by robot-assisted therapy showed significant effect, but no difference exists between the robot-assisted therapy and conventional therapy groups in terms of upper extremity function and functional ability. Conclusions : Robot-assisted therapy has been widely used clinically for stroke patients to maximize the effect had been applied to various interventions. Robot-assisted therapy depending on the methods of intervention showed that the effect of difference. In the future study, the use of robot-assisted therapy applied to a variety of interventions is needed on occupational therapy.
