If vibration occurs due to fast movement of the robot, the camera image is unstable. No longer the eyes of a robot can not perform the role. Research methods for the stabilization of shaky video is required. The most popular method is to use the motion vector. But, the drawback to this method will require a large amount of operation. And the limits of the embedded robot. Therefore, in real-time transmission of images to be difficult. This paper proposes a motion sensor using the image stabilization. Uses data that is output from the motion sensor. So, not related to the progress of the robot movement is a way to remove it from the video.

In this study, the robot arm control system was implemented that is operated by human hands, which can be used in environments that are inaccessible to humans. This function has to be sent to the robot's arms after extracting coordinates of human hands. Through mapping and bluetooth communication we use a leap motion sensor with infrared light and Image recognition sensor.

인간과 의사소통 및 상호작용함에 있어 휴머노이드 로봇은 그 외형이 인간에게 친숙해야 할 뿐만 아니라 그 행동역시 인간과 유사해야 한다. 인간의 상체 동작과 유사한 동작은 인간과의 의사소통에 있어 매우 중요하다. 인간의 동작과 유사한 동작을 수학적인 식을 통하여 생성해 내기는 매우 힘들다. 수학적 모델을 개발하려는 노력과는 달리 최근에는 모션캡쳐 장비로부터 동작데이터를 획득하고, 그 데이터를 휴머노이드 로봇에 입력하는 연구가 진행되어왔다. 하지만, 로봇과 인간이 의사소통함에 있어서 필요한 모든 데이터를 모션캡쳐 장비로 획득하여 저장해 놓기는 불가능 하다. 또한, 동작을 통하여 의미를 전달하는 의사소통의 경우에 상대방과 분위기에 따라 동작의 방향이나 크기를 달리할 필요가 있다. 이 논문에서는 의미가 있는 동작을 모션캡쳐 장비로부터 획득하고, 휴머노이드 로봇에 맞게 변환한 다음, 그 데이터를 상황에 맞게 실시간으로 변형하는 방법을 제안한다. 제안한 방법을 몇가지 동작에 적용하여 그 실효성을 검정하였다.

An effort for motion control of multi-axis in robot have been continued recently. In this paper, we propose implementation method for AC servo driver that can be easily motion control of multi-axis in robot. This proposed method implement EtherCAT communication technologies of bi-directional optical communication based on single optical core method that applied WDM for communication between control stage which is upper and AC servo drive stage.

In this paper, we propose an efficient Robot Performance System (RPS). For the proposed system, a soundboard was developed and inserted into the body of a humanoid robot to enable audio playback without an external playback device; the hardware required to enable the external storage device within the soundboard to remember the sound sources necessary for performances was developed. Furthermore, a specialized performance scenario planning software called Robot Performance Planning Development Program (RPPDP) was developed to allow users to search through a motion database for the robot's default motions, applied motions, and motions for special circumstances, allowing anyone to plan a robot performance at a low cost in a short amount of time.

This paper was researched the straight cruise of fish robot according to biological mimic, and it was compared the proposed method which was considered up to 7th order components in fourier series of Liu's tail motion function with the approximate method which was used general sine function by simulation. If fish robot has a large number of links and if the length of tail link is long. The end rotary joint trajectory of tail motion function generally is different from sine function. Therefore The approximate method which expresses tail motion trajectories as fundamental component in fourier series has a problem. Through the computer simulation, the proposed method showed 10% excellent propulsion and velocity than the conventional method.

As humanoid robot technology advances, the use of robots for performance is increasing. As a result, studies are being conducted to increase the scope of use of robots in performances by making them natural like humans. Among them, the use of motion capture technology is often used, and there are environmental inconveniences in preparing for motion capture, such as the need for IMU sensors or markers attached to each part of the body and precise high-performance cameras. In addition, for robots used in performance technology, there is a problem that they have to respond in real time depending on the unexpected situation or the audience's response. To make up for the above mentioned problems, in this paper, we proposed a real-time motion capture system by using a number of RGB-D cameras and creating natural robot motion similar to human motion by using motion-captured data.
