  • The ability to overcome obstacles is necessary for field robots for various applications including the ability to climb stairs. While much research has been performed focusing on overcoming obstacles, the resulting robots do not have sufficient ability to overcome obstacles such as stairs. In this research, the purpose is to overcome relatively large obstacles by flipping locomotion through the modification of the stair climbing robotic platform of the previous research. We propose two scenarios to overcome large obstacles: a rear wheel driving system and an elevation system using a ball screw. The research is performed based on static analyses on obstacle-climbing. As the simulation results indicate, we determined the optimal posture of the robot for climbing obstacles for rear wheel driving. Also, an elevation system is analyzed for obstacle climbing. Between the two scenarios an elevation system is determined to reduce the operating torque of the actuator, and the prototype was recently assembled. The climbing ability of the robotic platform is verified. We expect the application area for this robotic platform will be in accident areas of nuclear power plants.

  • 본 연구는 6주간 20대의 일반 대학생을 대상으로 척추 정렬과 균형능력에 대한 클라이밍 운동 프로그램이 자기효능감에 미치는 영향에 대해 알아보았으며, 실험대상자는 총 30명이었으며, 6주간 주 3회 씩 상지와 하지에 대한 클라이밍 운동프로그램을 실시하였고, 결과는 다음과 같았다. 자기효능감의 군내 비교에서는 훈련군에서 유의한 차이가 있었다. 따라서, 클라이밍 운동이 자기효능감에 정상성인의 동기부여를 향상하는데 영향을 줄 수 있다는 것을 알 수 있었다. 결론적으로 추후 다양한 실험자들에게 클라이밍 운동을 실시할 시 참고 자료로 사용될 수 있을 것이라 사료된다.

  • A variable configuration tracked vehicle(VCTV) is developed to reduce turning energy and improve climbing ability for stairs. This mechanism has four track T-type frames. By changing the driving direction, each track T-type frame rotates to minimize the contact area with ground. It also has better performance than other VCTV in energy consumption of turning. Futhermore this mechanism is more stable than other VCTV on the rough terrain. When climbing stairs, each track T-type frame rotates to obtain a front attack angle and keep stability on steep stairs. The design parameters of components of track T-type frames are optimized to enhance the performance of climbing stairs. Performance indices include a stable angle, a climbing ability, a height of the vertical obstacle. In case that the overall length of the mechanism is 0.2m, it is required that the radius of the wheels should be 5mm and the length track contacted with he ground should be 0.09m to climb higher and steeper stairs.

  • In this paper, we propose a cable climbing robot which can climb up and down the cables in the bridges. The robot mechanism consists of three parts: a wheel based driving mechanism, adhesion mechanism, and safe landing mechanism. The wheel based driving mechanism is driven by tooth clutches and motors. The adhesion mechanism plays the role of maintaining adhesion force by a combination of pantograph, ball screw, and springs even when the power is lost. The safe landing mechanism is developed for guaranteeing the safety of the robot during operations on cables. It can make the robot fall down with reduced speed by dissipating the gravitational forces. The robot mechanism is designed and manufactured for validating its effectiveness.

  • Recently the concurrent construction method of framework and windows work has been applied for early beginning of exterior finishing works in tall building construction. However, the conventional method makes difficulties in auto-climbing of gang-form and climbing work of lift car since the removal of ACS(auto climbing system) should be preceded for operation of lift car up to the top floor. This study propose a concept model of integrated ACS and lift car system to resolve these problems and begin windows works early in tall building construction.

  • Recently people have increased to climb mountain. Owing to developing IT technology, the number of people using smart phone have increased remarkably as well. In this context, the Korea Forest Service has implemented the project of Mountain Climbing Information Public Service(MCIPS). The purpose of the MCIPS is to support climbing safely based on a trail map of spatial data of GIS(geographic information system). The customer will be able to access the MCIPS through n-screen(IP-TV, Web Site, Smart phone, Galaxy tab) provided a broadcasting and telecommunication convergence service. In addition, the MCIPS would support two-way communication through connecting to Twitter and Youtube. The MCIPS will make the customer fun using Augmented Reality(AR) of Smart phone(Android) and contribute to protecting people from mountain accidents.
