In domestic railway stations, transporting cargo using overhead cranes is difficult because of the catenary lines. Horizontal moving piggy-back transfer technology is a method of transporting trailers or cargo together with trucks on freight trains while avoiding the catenary lines. This thesis is a study on the design technology of piggy-back loading and unloading transfer facilities that satisfies all the conditions necessary for the use of the existing railroad network in Korea. By developing a shuttle system, including an air cushion transporter and a docking unit, the piggyback transport system was designed. This technology is expected to improve railroad logistics technology and expand the logistics market.

In this paper, important design parameters for parallel kinematic robots are defined, paying special attention to machining errors which may cause kinematic errors at the end effector of a robot. The kinematic effects caused by each design parameter, as well as their upper/lower limits, are analyzed here. To do so, we have developed a novel software program to compute kinematic errors by considering its defined design parameters. With this program, roboticists designing parallel kinematic robots can understand the important design parameters for which upper/lower allowances have to be strictly controlled in the design process. This tactic can be used for the design of high-speed, parallel kinematic robots to reduce the design/manufacturing costs and increase kinematic precision.

In this study, economic feasibility analysis was performed when various hydrogen production and transport technologies were applied to derive hydrogen supply plans by period. The cost of hydrogen may vary depending on several reasons; configuration of the entire cycle supply path from production, storage/transportation, and utilization to the cost that can be supplied to consumers. In this analysis, the hydrogen supply price according to the hydrogen supply route configuration for each period was analyzed for the transportation hydrogen demand in metropolitan area, where the demand for hydrogen is expected to be the highest due to the expansion of hydrogen supply.

In this paper, a hybrid roll for a roll-to-roll hot embossing system to fabricate micro patterns is studied. In previous studies, heating rolls are widely used to heat the polymer substrate for embossing process, so the rolls only give heat to the substrate. The hybrid roll studied in this paper can be used as not only a heating roll but also a cooling roll. It is expected that more flexible process can be designed if the hybrid roll is used in the roll to roll hot embossing process. Some analysis to design the roll is presented in this paper.

Recent trends in transport system for carrying heavy freight are that demands of a high efficiency, economic efficiency, convenience and safety are increased. Conventional transport systems were poor in transport efficiency and economic efficiency. And Safety problems can be caused to products and workers. In order to overcome these problems, an air cushion transport device with a high-pressure air is required. The air cushion transporter is a device for reducing the frictional force of floor surface and lifting the heavy freight by spraying the high-pressure air to the floor. Technology to float and transfer freight using high-pressure air is very convenient and initial cost can be reduced. In this paper, the study on the levitation performance and transport efficiency of air cushion transport system is conducted and verified that air cushion transporter has a significantly higher transport efficiency than conventional heavy handling systems.

These days, the interests on the high speed handling robots are increasing because it is important to get down the unit cost of production to get the price competitiveness. The parallel kinematic mechanism is more suitable to implement the high speed robot system as well known. The moving parts of the high speed parallel robot have to be designed for light weight. But the vibration motion is induced by the light weight links because they drive in high acceleration and deceleration. In this reason, the structural analysis of the high speed parallel kinematic robot is very important in the design process. In this paper, the study on the structural analysis of a high speed parallel robot has been done and the research results will be introduced.
