팬틸트 카메라 제어를 위한 자세측정 장치 기반 이동로봇플랫폼 구현

비상체가 자세를 유지하기 위한 자세기준에는 비상체의 무게중심을 지나 서로 직교하는 3축을 취하는데 그것을 각각 롤(roll)축, 피치(pitch)축, 요(yaw)축 이라 부른다. 자세측정 장치는 이 3축에 대한 변동을 검출하는 센서이다. 본 논문에서는 HMD에 자세측정 장치를 부착하고. 이동로봇플랫폼에 팬틸트를 장착하여 카메라를 제어한다. 가속도센서는 진동에 매우 취약하기 때문에 센서데이터에 노이즈가 심하게 발생하며, 센서데이터를 매핑(mapping)하는 과정에서 데이터들의 간격이 많이 벌어지는 문제도 발생한다. 이러한 문제점을 해결하기 위해 평균필터와 Cosine Interpolation을 적용하여 팬틸트 동작을 방해하는 요소를 제거하였다. 제안한 성능을 평가하기 위해 실외환경에서 HMD에 부착한 센서데이터를 원격으로 전송하여 이동로봇에 탑재된 팬틸트 카메라를 제어하였다. 실험결과 약간의 지연은 발생하였으나 비교적 안정하게 팬틸트 카메라가 제어됨을 확인할 수 있었다. 또한, 이동로봇은 평지나 경사면 등 어떠한 지형에서도 주행이 가능함을 확인할 수 있었다. Aircraft have a cross axis of the three each other for maintenance of aircraft position. It is called roll axis, pitch axis and yaw axis. Attitude reference system is a sensor for detecting a change of the three axis. In this paper, mobile robot platform install part of Pan-tilt and HMD attitude reference system, because of we use control camera. The acceleration sensor is very weak a lot of noise to vibration, also problem with data from process of mapping to the data problems to arise. However to solve this problem, we removed the average filter and Cosine Interpolation for Pan-tilt. Using capacity evaluation for outdoor environment for we are proposing. Mobile robot has HMD and equipped Pan-tilt. We control mobile robot camera. In this experiment result is little bit delay happening, however Pan-tilt camera is relatively stable control checking. Also, we will checking any terrain and slopes is no problem for mobile robot driving skills.

This paper presents bio-ethanol production from fruit wastes as it possibly alternate fossil fuel in the future. To illustrate the component ratio in exocarps of fruit wastes such as pears, apples, and persimmons, the amount of moisture, lignin, -cellulose, and ash content were respectively examined by the ingredient analysis. Also, the amount of the glucose obtained from the enzyme hydrolysis using the axocarps was investigated. It was found in our results that the energy efficient process requires different temperature conditions for the saccharification step(50℃) and the fermentation step(30℃) in ethanol synthesis.

This paper investigates the dehydration and RDF (Refuse Derived Fuel) production of organic wastes, livestock manure and sewerage sludge with pressurized hydrothermal treatment process. The renewable technology for the organic wastes must involve short treatment time required, reusable energy source, anti-odor and viruses, low cost for the treatment, and well-fertilization. The pressurized hydrothermal treatment process promotes to evaporate moisture in the waste after being shortly treated in a reactor, which uses steam and heat supplied by an external boiler. By the pressurized steam, the cell walls of the waste break and effectively release the internal moisture. Then, the dried waste can be mixed with waste vinyls to produce RDF with a higher heating value as high as 6,700 kcal/kg.

Horse racing has become one of the most popular leisure activities in Korea, having more than 16 million visitors in 2012. This study examines the relations between experiences at a horse racing park, attitude towards horse racing, and behavioral intention. In this study, five constructs of experience have been developed through reviewing the literature, and an on-site survey was conducted at Seoul Horse Racing Park on November 2012. The results of structural equation modeling analysis showed that hedonic and education factors have positive influences on the attitude towards horse racing. However, the other three factors of utilitarianism, relations and escapism, did not have significant effects on the attitude. The relation between attitude and behavioral intention on horse racing showed a very high correlation, with lack of discriminant validity. The findings suggest that Seoul Horse Racing Park should focus on hedonic and education factors for their marketing and promotion.
