The exploration task is defined as a problem of generating minimal-cost path, in which robots go through several observation points and observe a working environment. Both number of the observation points and path length should be minimized. The proposed algorithm has two characteristics: efficiency in exploration and adaptability to dynamic environmental changes. Our method can be realized with the combination of (a) distribution of observation points by a reaction-diffusion equation on a graph, and (b) generation of a Hamiltonian circle that connects all observation points. The observation points dynamically change their arrangements in accordance with the recognized environmental situation. The calculation cost for exploration path generation is shown to be in order of N/sup 1.5/, where N is the number of the observation points. Our method can be extended into cooperative exploration path planning method. Our method homogenized the arrangement of the observation points, then only a basic partition method can equally part exploration task for each robot. The effectiveness of our method is shown by both simulation and real robot experiments.","PeriodicalId":344984,"journal":{"name":"2002 IEEE International Conference on Industrial Technology, 2002.

To fabricate such inserts, the diamond tool has to be tilted sufficiently to achieve an effective flank angle of around 30 degrees. The maximum flank angle should be kept lower than 15 degrees to ensure adequate strength of the tool cutting edge. Due to the tool tilt, two types of form errors have to be addressed: the form error arising from the presented tool nose changing from circular to elliptical curvature, and the cone form error caused by the tool flank interfering with the center portion of the machined profile. The first type of form error can be eliminated by using a tool path correction procedure. For the second type of form error, theoretical and experimental investigations were conducted to determine the effects of the diamond tool tilt, the rotated angle and the tool nose radius on the center cone form error. This produces information on the correct tool radius and rotated angle required to minimize the center cone form error. With the above two procedures, the form error of deep-sag aspherical profiles can be improved significantly from 22 /spl mu/m to 0.11 /spl mu/m.","PeriodicalId":344984,"journal":{"name":"2002 IEEE International Conference on Industrial Technology, 2002.
