A new method for global path planning of mobile robots is presented using an Evolutionary Strategy (ES). A two-dimensional autonomous path planning problem of a point mobile robot among polygonal obstacles is formulated as a constrained time-optimal control problem considering motions of the robot. From the visibility concept, each polygonal obstacle is enclosed by a circle so that the visible side...
This paper describes a Takagi-Sugeno (T-S) fuzzy model adopted solution to the simultaneous localization and mapping (SLAM) problem with two-sensor data association (TSDA) method. Fuzzy Kalman filtering of the SLAM problem (FKF-SLAM) is used in this paper together with newly proposed data association algorithm. An extended TSDA (ETSDA) method is introduced for the SLAM problem in mobile robot navigation...
This paper proposes a method for evaluating fuzzy voice commands (FVCs) by user guided visual attention. FVCs inherit fuzzy linguistic information due to the inclusion of fuzzy linguistic terms such as ??very little.?? The contextual meaning of such information depends on the environmental arrangement. Therefore, visual attention system (VAS) is utilized to evaluate the fuzzy linguistic information...
