In this paper we try to develop an algorithm for visual obstacle avoidance of autonomous mobile robot.The input of the algorithm is an image sequence grabbed here by an embedded camera on the B21r robot in motion.Then, the optical flow information is extracted from the image sequence in order to be used in the navigation algorithm.The optical flow

This paper presents an original stochastic method of optimization (PGSL) for optimum design of truss structures.PGSL (Probabilistic Global Search Lausanne, developed at the Swiss Federal Institute of Technology at Lausanne) has been inter-faced with a finite element code, then 30hh bikini applied and tested on several size optimization problems of

Yogyakarta is a city tourism that has no natural tourism potential.Shopping tourism can become an alternative strategy to increase the expenditure and length of tourists stay in Yogyakarta.The research is a qualitative research.The research aims equi-jec 6 to examine shopping tourism products in Yogyakarta.The research attempts to identify top five

Hand-eye calibration enables proper perception of the environment in which a vision guided robot operates.Additionally, it enables the mapping of here the scene in the robots frame.Proper hand-eye calibration is crucial when sub-millimetre perceptual accuracy is needed.For example, in robot assisted surgery, a poorly calibrated robot would cause da
