  • Technology-based convergence education is being emphasized for students in the era of the fourth industrial revolution. In math education, students need to increase their capabilities in the future by having them experience mathematical problems using robots and sensors, a key technology in the era of the fourth industrial revolution. To this end, it is necessary to present educational uses for educational robots in relation to math and curriculum from a 'mathematics education perspective' and analyze its educational use in relation to the mathematics and curriculum, considering the role of mathematics at the base of the process of exploring real-world phenomena and solving problems. Based on the analysis of Van Hiele levels of development in geometry and the LOGO activity level of Olson et al.(1987), this study analyzed and presented the level of LEGO Mindstorm activity, a representative educational Robot capable of collecting and analyzing data and programming in the form of block language, in the first to fourth level.

  • Recent advanced interlace technologies allow the user to interact with different spaces such as Virtual Reality (VR), Augmented Reality (AR) and Ubiquitous Computing (UC) spaces. Here, we present a LEGO House application, a collaborative application which involves multi interaction spaces -VR, AR and UC spaces. The LEGO House application is built based on the VARU framework which is designed for enabling the prototyping of a tangible space application. The application is about an interior design. One user is located in the combined AR and UC space and interacts with the AR LEGO house and the physical smart devices. The other users interact with the virtual LEGO house but they share the same environment, the LEGO house. Therefore, they can collaborate together as they are co-located.

  • In this paper, we describe a case study of a new lab. project that improves efficiency for education and interest on learning in image processing and pattern recognition related subjects by using LEGO Mindstorms. In addition we verify the validity with analysis of the practical application. LEGO Mindstorms is already used in many educational institution of several countries since about 10 years ago and various case studies have been published. The use of LEGO Mindstorms is generally positive but the negative comments about this exist. The main cause of negative opinion is from unpredictability. The unpredictability from mainly analog characteristics of robot can degrade the effective learning. The describing lab. project suppresses occurrence of unpredictability by minimizing dependence on robots. Students can concentrate on learning the related algorithms by minimizing the learning content and further consideration.

  • In this paper the author proposes a case study of a freshmen introduction to engineering design course ing LEGO Mindstorm NXT and analyzes the survey results of the course. The diffilculties are that this course should provide various aspects of design experiences to the students while not requiring the major knowledge and skills and it should attract the students to the engineering major. According to our case study LEGO mindstorm can be a good solution to this problem. The design experience with LEGO Mindstorm NXT provides students with various aspects of design experiences including defining problem, finding constraints and functions, exploring design space, and performing preliminary design, as well as fun. This paper also provides a project list that can be used for freshmen design experience including soccer game robots, line tracer, and vacuum cleaner etc.

  • Lego block system forms a temporary pavement area using the assembled structure block in the road excavation work for the maintenance and installation of facilities. This system was developed for a safe passage of vehicles and pedestrians. A study on the fundamental performance of a lego block system was performed through material quality, sliding resistance and compression tests. And compaction performance of ground on the road was reviewed and evaluated through field tests. As a result, a lego block system for road recovery showed the excellent performance and compaction effect.

  • In this paper, we propose a method to solve the difficulties in constructing an environment capable of practical training on the theoretical contents of robot control field. We make a two-wheeled mobile robot with Segway structure using LEGO block. In order to demonstrate the validity of using the developed robot as a practical application of advanced control theory of robotics education such as dynamic system and nonlinear system, the robot takes a stable posture while balancing the change of gravity during running. The results of the experiment are shown. By presenting the results, the robots made using the LEGO block are used for practical training of advanced control theory of robotics. It can be used as a tool.

  • This paper deals with the selection method of effective engineering design problem based on LEGO Mindstorm NXT for basic design education. By YouTube case study of various LEGO-based engineering designs for olympic sports, performance criteria have been developed including programming complexity, structural complexity, sensor/actuator complexity and variety of game operation. Programming complexity includes range of programming code length and possible program variety. Structural complexity includes variety of structural elements such as length, shape, weight, and volume to overcome design restrictions. Sensor/actuator complexity includes variety of sensor used and number of possible actuator assemblies. Variety of game operation includes game complexity and required creativity to make LEGO robots. Based on these performance criteria, four representative sports were selected as the candidates for effective engineering design problem. Finally, feasibility and attributes of each candidate were verified by real implementation examples.

  • We present a legorization framework that produces a LEGO model from a voxel model. Unlike other frameworks, we include bricks whose height is more than one layer. Furthermore, we devise a two-colored graph that represents the adjacency and stability information of a LEGO model. Our legorization is composed of tiling process on each layer, which is implemented using a heuristic search algorithm. We legorize five models including characters and buildings to prove the excellence of out framework.
