This paper proposes elementary robot programming problems using the algorithmic thinking-based problem model with material factors in the elementary robot programming. And this paper proves the validity of developed robot programming problems in defining them as algorithmic thinking-based problems through experiments. The experimental results are analyzed in views of variety and effectiveness evaluation of answer algorithms and suitability of allocating degrees of difficulties to the developed robot programming problems. As a result of the experiment, we find that the developed problems has various answer algorithms and suitable degrees of difficulties for elementary school students.

This paper presents a task teaching method for off-line programming of a multi-robot system. Teaching commands were developed in order to simplify a complex teaching process, to shorten the setup time for new working environment and to have flexibility for changes in working environment. Four teaching commands can be used to automatically generate trajectories of an end-effector of the robot in electronics assembly line. The robots used in the work cell are a four-axis SCARA robot and six-axis articulated robot. Each robot is controlled in a independent way while objects, working environment and robots are modeled in corresponding modules, respectively. The off- line programming system developed uses OpenGL for a smooth graphic effect in Window s where three dimensional CAD data can be leaded for graphical modeling.

The problem of robot navigation and control is a complex task. Its complexity and characteristics depends on the characteristics of the environment robot inhabits, robot construction (mechanical abilities to move, sense) and the job the robot is supposed to do. In this paper we propose a hybrid programming approach to mobile robot navigation and control in an indoor environment. In our approach we used declarative, procedural, and object oriented programming paradigms and we utilized some advantages of our distributed computing architecture. The programming languages corresponding to the paradigms we used were C, C++ and Prolog. In the paper we present some details of our mobile robot hardware and software structure, focusing on the software design and implementation.

This paper describes an experimental system for automatic robot programming, The SNU-ARPS (Seoul National University Automatic Robot Programming System). The SNU-ARPS generates executable robot programs for pick and place operation and some simple mechanical assembly tasks by menudriven dialog. It is intended to enable the user to concentrate on the overall operation sequence instead of the knowledge regarding the details of robot languages. To convert task specifications into manipulator motions, the SNU-ARPS uses an internal representation of the world. This representation initially consists of geometric database from CAD system and is updated at each operation step to reflect the state changes of the world.

The programming learning by using a robot may be one of the most appropriate learning methods for enabling students to experience the creative learning of future society by avoiding the existing stereotyped style educational environment, and understand and improve algorithm which is the basic fundamental of mathematics and science. This study proposed four types of items of errors which may occur during robot programming by elementary school students, and made elementary school students in the fifth and sixth grades learn robot programming after developing the curriculum for the robot programming. Then, the study collected and classified errors that had occurred during the process of learning, and conducted a comparative analysis of computer-based programming language which had been previously studied. This study identified that robot programming in elementary school was shown superior to existing computer-based programming language as a creative learning method and tool through the field experience.

The purpose of this study is to develop a subject integration robot programming instruction model to improve information gifted elementary students' creativity. For this goal, we have developed a subject integration robot programming instruction model and verified its effectiveness. The developed instruction model was applied to the 5th and 6th grade elementary school students. The developed model was applied to the experimental group and ordinary robot programming instruction model was applied to the comparison group. As a result, the model was significantly enhance students' creative disposition and creative cognitive abilities. According to these results, it has been proved that the subject integration robot programming instruction model is effective to the information gifted elementary students' creative disposition and creative cognition abilities.

Most of the robot programming curriculums consists mainly of understanding robot programming language and learning a simple grammatical sentences rather than logical problem solving process, these curriculums impose a burden on childrens' learning. Storytelling offers opportunities for continuation of childrens' positive learning motivation to practice symbolic manipulations, hold multiple abstract concepts in their heads, and create meaning between these ideas. In this paper, to overcome the difficulty of robot programming curriculum in elementary school and find teaching method which derives the childrens' motivation, we used storytelling in study of our robot programming curriculum.

Robot assisted programming education has been highlighted because it enhances the involvement of students. Robots are combined with mechanical and program elements. However, in after school Robotics classes, almost all is education for the mechanical elements of robots. On the other hand, education for robot programming is a starting stage. It is difficult for students to programming with sensors. Therefore, in this paper, I researched the relationships between elements from sensors to output devices. And I applied it to Robotics education. As a result, the students can understand robot because they studied the relationships between data from sensors and output devices. We proved it by the survey after the relationship education.

Using robots in the programming classes may help to induce learners' interest and motivation. However, simple introduction of new media, such as robots, may cause to increase learners' interest level temporarily, but also may give cognitive overload and offense against learning motivation. We developed a robot programming course to induce intrinsic motivation and to reduce cognitive load for learners in the programming education. And then, we implemented the developed course in college programming classes and analysed the educational effects of robot programming learning on novice learners' flow level. We found that robot programming course was helpful in enhancing novice learners' flow level. Especially, the element of 'autotelic experience', which explains an intrinsic motivation, was higher than conventional programming course group. It means that the developed strategies for robot programming course provides positive effects on learners' intrinsic motivation.

As international market pressures increase, product life cycles are becoming shorter at same time requirements for productivity and flexibility are becoming higher. Major improvement in robot programming user interface is central to increasing productivity and flexibility for automatic manufacturing environments. New computer technologies have the potential to accomplish this improvement. In this study we have developed a system which proves that interactive computer graphics and geometric modeling have matured to the point where their artful application into an integrated system can rsult in radically new and powerful user interface for robot programming. With the graphic user interface environment the system efficiently utilizes the existing CAD data and gemetric modeling techniques for off-line programming and simulations. Also the system successfully generates robot control programs performing the desired tasks given through off-line programming.
