摘要： A method and an apparatus for predicting interference, at practical accuracy and calculation time, between a target section of a robot and a peripheral object installed around the robot, when the target section, such as a tool or a sensor attached to a robot hand, is moved along a movement path thereof due to the motion of the robot. A convex hull, defined by areas occupied by the tool at adjacent time points, is calculated. It is judged whether a common area exists between the convex hull and a polyhedron area. When the common area exists, it is judged that the tool interferes with the container box on the movement path, and the procedure is terminated. When the common area does not exist, it is judged whether j

摘要： (1) Orthogonal transformation is applied to sample images based on the images of a normalized orthogonal system, and component groups are determined. A plurality of comparison target images are selected from an input image, and a partial normalized orthogonal system is created from the normalized orthogonal system by decreasing the dimensions. (2) Based on the partial normalized orthogonal system, orthogonal transformation is applied to the comparison target images, so as to determine the partial component group for each comparison target image. A comparison target image having high consistency with one of the sample images is extracted by comparison and collation between these partial component groups and the partial component groups which include each element of each partial normalized orthogonal system among component groups of each sample image. And a new comparison target image group is selected near the extracted image, and a new partial normalized orthogonal system is created by increasing the dimensions. Then (2) is repeated.

摘要： An interpolation method for enabling a robot to make a smooth connecting motion accompanied by velocity control even in the case where the connecting motion involves a nonzero-acceleration motion. During motion path planning for the robot, in order to perform an interpolation so that a point a.sup.(0) on a first motion path G and a point b.sup.(0) on a second motion path H may be smoothly connected by a connecting curve S, the connecting curve S being determined using a parameter including time instant t. First, a function p(T, t) satisfying boundary conditions (continuity of position, velocity, acceleration, etc.) corresponding to required smoothness C.sup.k is derived as a polynomial equation or the like including an unknown parameter T, and by optimizing a suitable evaluation function .epsilon.(T), T.sub.0 for keeping the velocity constant is obtained. Interpolation is performed using q(t)=p(T.sub.0, t), whereupon a connecting motion, in which the velocity is controlled to a constant value, can be attained. Where a composite function (q.smallcircle.f)(t) including an adjustment function f(t) corresponding to a desired velocity transition pattern is used for the interpolation, the velocity can be varied in a desired manner during the connecting motion.

摘要： The entire region of variation in the viewing range of the attitude of a workpiece is divided roughly, and images of the workpiece are captured from each direction. The images are stored together with imaging direction data as a first teaching model. Images captured by varying the imaging direction at a narrow pitch within a predetermined range of attitude variation in the workpiece are then stored together with imaging direction data as a second teaching model. Images of the workpiece are captured and compared with the teaching models. The position and attitude of the workpiece are determined by the imaging direction and imaging position of the selected teaching model.

摘要： A first masking image of an input image is created by assuming that pixels in an area including the area of a target in all sample images are valid pixels while pixels in the remaining area are invalid pixels. The first masking image is used in a first comparison between the input image and each sample image to select an image that provides a best match as a provisionally selected sample image. In a second comparison, a second masking image corresponding to the provisionally selected sample image is used to select a final sample image. The second masking image is created from an individual sample image by assuming that pixels in an area including the area of the target are valid pixels while pixels in the remaining area invalid pixels.

摘要： A group of bolts are suppled into a placing surface of a tray, an isolated bolt is searched for by a visual sensor, and its deviation from a standard position at the time of teaching is determined. The isolated bolt is picked up by a robot that has been taught how to pick up an isolated bolt laying in a standard position. The position of the robot's hand is corrected according to the deviation from the standard position before the robot attempts to pick up the located isolated bolt. If no isolated bolt is found, a shaking device 1 is operated to loosen the piled-up bolts, and a new isolated bolt is again searched for by the visual sensor. The isolated bolt, if found, is picked up. The picking-up operation may be performed by searching for an isolated small set of bolts using a three-dimensional visual sensor. The oscillating excitation can also be provided by a robot. Also, the piled-up bolts may be loosened or disentangled using a robot equipped with a tool for leveling the pile of bolts or by using a gas jet.
