This paper is experimental study to inspect effects of problem solving ability and programming interest using Pico Cricket of the educational robot. The programming learning which is regarded as the very core of information subject improves problem solving ability. But the programming teaming does not display the effects properly, because the programming learning studies a grammar manual. The educational robot has the advantage to approach the programming learning easily for containing entertainment. The Pico Cricket of the educational robot has the advantage not to induce competition but to compose a cooperative learning environment. Also, the Pico Cricket is able to be had interest of programming learning to girl students, because the Pico Cricket is able to suggest life-centered and cooperative contents which girl students like. Accordingly, This paper is study which the programming learning using Pico Cricket affects the problem solving ability and programming interest and men and women's comparison study.

In this paper, we show how a curriculum using LEGO MINDSTORMS NXT robot based ROBOTC for undergraduate students has been developed, and we analyze the educational effect of the curriculum. The curriculum is composed of basic knowledge learning, practice with basic robots, practice with advanced robots, and creative design and implementation of robots. During the three year period since 2009, educational achievement has been analyzed by surveys for 6 classes, 94 students. According to the analysis, the curriculum has highly motivated the students and made them to achieve effectively our educational and academic goals. Also, we observe that the curriculum helped the students to improve their creativity and the problem solving skill, and that the students were autonomously and deeply involved in the homework and the term projects, which made them be very cooperative. Finally, the intensive practice with ROBOTC programming is shown to help students to improve their programming ability of C language.

In recent years, dangerous materials and gas leak accidents have been frequently occurred. The hazardous materials storage facility accidents are not rapidly controlled when a leak is detected, unlike other chemical plants can be controled. Externally, the human has to approach and respond to the source of leaking directly. As a result, the human and material damage are likely to larger result in the process. The current approach has been passive response after ringing the alarm. In this study, the suggested tracking system of the leak resource is designed system to track the resource actively by utilizing the mobile sensor robot platform, which can be made easily through recent rapid development technology, is verified through prototype system. Thus, a suggested system should pave the way for minimizing the spread and damage of the accident based on the exact site situation of the initial leak and quick and early measures.
