in this project guidance and control of underwater robot, including three engines and propeller attached to it, by fuzzy control has been investigated. fuzzy control is done based on human experience and requiered laws. the robot can also be controlled and guided by the user. this robot may be used in sea or swimming pool environment for finding goal point and locate in desired direction. in ad...

although construction has been known as a highly complex application field for autonomous robotic systems, recent advances in this field offer great hope for using robotic capabilities to develop automated construction. today, space research agencies seek to build infrastructures without human intervention, and construction companies look to robots with the potential to improve construction qua...

This paper reports on a programming lesson using autonomous robots in junior high school. First, the design of the low cost circuit board for the lesson is described. The structure of a general programming language “Dolittle” which controls a robot is also explained. Then, we introduce lessons of manufacturing and controlling robots in “Information and Computer” area of “Technology and Home Eco...

Finding information in large scale autonomous heterogeneous databases is an issue that has been virtually unexplored in database research. We describe a new approach for nding information in a large scale network of autonomous and heterogeneous databases. In our scheme, no a priori knowledge of the database schemas or the space of information is necessary to locate information. The system relie...

The principal function of the CSCL environments is to provide to the various users (students, teachers, tutors, etc.) the best activities with the best tools at the best time according to their needs. If a CSCL system is a collection of activities or learning process, we can cut out its functionalities in a certain number of autonomous functions which can then be carried out separately in the f...

Physical education teachers can influence students' self-determination through the motivational strategies that they use. The current study examined how teachers' reported use of three motivational strategies (providing a meaningful rationale, providing instrumental help and support, and gaining an understanding of the students) were predicted by perceived job pressure, perceptions of student s...

There is no robot around us in our society at the current stage if we define a robot as an autonomous machine working in the arena of offices, homes, and disaster sites, etc. outside the factories. Mechatronics, dynamics and robotics involving humans are the world of strong nonlinearity. This paper investigated the approach to the emergence of the objective behavior of an autonomous mobile robo...

This paper reports on a Naval Engineering Education Center (NEEC) design-build-test project focused on the development of a fully autonomous system for landing Navy unmanned aerial vehicles (UAVs) on transiting ships at sea. Our NEEC team of engineering students researched image processing techniques, estimation frameworks, and control algorithms to collaboratively learn and train in Navy-relev...
