User's Motion for Shape Perception Using CyARM
No full textWe have developed a new sensing device, named by “CyARM“. CyARM is one of Active Perception device, based on activeness of human perception. In order to clarify information for shape perception using CyARM, an experiment had conducted. Results of this experiment show that shapes with sharp edges are identified easily, but shapes with smooth edges are identified with greater difficulty. In other words, the subjects perceived changes in distance from the sensor to the object as object edges. Furthermore, from the results of multi-dimensional scaling, it is suggested that object shapes perceived by the subjects were classified according to the sharpness of the edge and by the ratio of height and width. In addition, motion analyses were conducted. The result shows, it is suggested that user tend to swing arm to front arm mainly in motion of lateral direction.Lecture Notes in Computer Scienc
Path Planning for Precision Farming based on Autonomous Vehicles
No full textThis paper describes the planning system for precision farming. Especially, the system aims to support GPS based autonomous tractor and its actuators. The farm tractor can run precisely in fields according to GPS based navigation. The actuators can be controlled variable according to the precise position in fields. Using the tractor and its actuators, we can realize precision farming according to several conditions in fields. In order to use the autonomous tractor system, the planning system is developed for storing the field information, navigating the tractor and planning the variable farm-work. In this paper, we describe the functions, especially the path planning of the system. To generate the optimum paths, we formulate the covering problem and apply the approach using genetic algorithm
