in this paper, a new method was proposed for the navigation of a mobile robot in an unknown dynamic environment. the robot could detect only a limited radius of its surrounding with its sensors and it went on the shortest null space (sns) toward the goal. in the case of no obstacle, sns was a direct path from the robot to goal; however, in the presence of obstacles, sns was a space around the r...

The paper deals with the wireless sensor-based remote control of mobile robots motion in an unknown environment with obstacles using the Sun SPOT technology and gives the fuzzy velocity control of a mobile robot motion in an unknown environment with slopes and obstacles. The model of the vehicle has two driving wheels and the angular velocities of the two wheels are independently controlled. Wh...

In this paper, two inverse problems of Stephen kind with local (Dirichlet) boundary conditions are investigated. In the first problem only a part of boundary is unknown and in the second problem, the whole of boundary is unknown. For the both of problems, at first, analytic expressions for unknown boundary are presented, then by using these analytic expressions for unknown boundaries and bounda...

We study the regulation of a firm with unknown demand and cost information. In contrast to previous studies, we assume demand is influenced by a quality choice, and the firm has private information about its quality capacity in addition to its cost. Under natural conditions, asymmetric information about the quality capacity is irrelevant. The optimal pricing is weakly above marginal costs for a...

The problems of the output regulations and/or disturbance reductions have attracted a lot of interest and have been actively researched in the consideration of the control problem for systems which are required to have servomechanism and for vibration attenuation in mechanical systems. It is well known that such problems are solvable using the Internal Model Principle in cases where the system ...

in this paper, we consider an inverse problem of linear heat equation with nonlinear boundary condition. we identify the temperature and the unknown radiation tern from an overspecified condition on the boundary

Unknown-unknown risks are unknown with consequences. This type of risk is the most difficult to deal with. From this perspective, innovative solutions and technologies needed like robotics. Many studies dealt how robotics raise efficiency safety levels provide enhanced service, collect analyze data for security efforts, assist in dangerous settings or disaster. research based on core target ide...
