This research is for selection of animal and establishment of guideline which for animal robot design for the purpose of emotionally disturbed children's psychotherapy. In the case of emotionally disturbed children because of poor expression about themselves's emotional condition, there are many restriction in the existing cure and educational method. Using research method of animal shape robot which is starting to make attempt since the late 1990s is effective to learning disturbed children. For the development of animal robot for psychotherapy of emotionally disturbed children first of all which animal is selected is very important. Therefore at the early stage of research preference surveyed to children including emotionally disturbed children and decide an object of animal robot. And what kind of shape is very preferred is also preference surveyed. Through focusing group interview about shape, color, facial expression, sound, and move which have an influence on outward shape design of robot, present the guideline which is needed to animal robot design for emotionally disturbed children.

Most of the recently developed robots are human friendly robots which imitate an animal or human such as entertainment robot, biomimetic robot and humanoid robot. Interest in these robots is increased because the social trend is focused on health, welfare, and graying. By these social backgrounds, robots become more human friendly and suitable or home or personal environment. The more biomimetic robots resemble living creature, the more human feels familiarity. Human feels close friendship not only when feeding a pet, but also when watching a pet having the food. Most of entertainment robots and pet robots use internal-type batteries and have a self-recharging function. Entertainment robots and pet robots with internal-type batteries are not able to operate during charging the battery. So far there have been a few robots that do not depend on an internal battery. However, they need a bulky energy conversion unit and a slug or foods as an energy source, which is not suitable for home or personal application. In this paper, we introduce a new biomimetic entertainment robot with autonomous eating functionality, called EPRO-1(Eating Pet RObot version 1). The EPRO-1 is able to eat a food (a small battery), by itself and evacuate. We describe the design concept of the autonomous eating mechanism of the EPRO-1, characteristics of sub-parts of the manufactured mechanism and its control system.

This paper proposes an optimal galloping trajectory which costs low energy and guarantees the stability of the quadruped robot. In the realization of the fast galloping, the trajectory design is important. As a galloping trajectory, we propose an elliptic leg trajectory, which provides simplified locomotion to complex galloping motions of animals. However, the elliptic trajectory, as an imitation of animal galloping motion, does not guarantee stability and minimal energy consumption. We propose optimization based on the energy and stability using a genetic algorithm, which provides the robust and global solution to a multi-body, highly nonlinear dynamic system. To evaluate and verify the effectiveness of the proposed trajectory, computer simulations were carried out.

Along with the recent increase in national income, social phenomena such as aging due to a decrease in population and an increase in single households are observed. There are also an increasing number of households raising pets in proportion to aging households and the increase in the number of single households, most of which use animal companions to overcome loneliness and boost domestic vitality. As more and more people consider pets as family members, the size of the domestic pet market is also growing. The growing number of pets in older households and single households is not properly managed by care such as food meals and exercise management for pets. It is necessary to research and develop robots that can monitor animal companions remotely, feed a certain amount of food at regular intervals, and manage their health through exercise. Among pet companions, dog selection is the highest. Therefore, this study identified robot research on driving methods, examples of existing pet care systems, and researched pet care robots using obstacle avoidance algorithms. In order to use the snack pay behavior and obstacle avoidance algorithm of the pet animals by applying IoT and we .oPI technology, it is able to use ultrasonic sensors on the front and has four infrared sensors on the back. However, this study does not reflect the characteristics of other pet animals as a study on pet care robots, and it requires continuous observation and testing.

본 연구는 동물을 위한 웨어러블 로봇을 개발하고, 이를 상황에 따라 적절한 보행을 제어할 수 있도록 강화학습(DQN 알고리즘)을 적용한다. 다양한 센서를 동물에 부착하여 얻은 데이터를 DQN 알고리즘에 입력으로 사용한다. 이 알고리즘은 수집된 데이터를 분석하여 어떤 상황에서 어떤 종류의 보행이 가장 적절한지를 판단하고, 이를 로봇에 적용하여 동물의 보행을 자연스럽게 구현한다
