摘要:
A method for measuring the three-dimensional position of an object to be captured. A laser measuring unit is provided having an image recognition camera confronting the object, first and second laser light emitting sources respectively irradiating from a slant direction a lateral slit light onto the object relative to a vertical axis of a vision coordinate system and irradiating a vertical slit light onto the object relative to a lateral axis of the vision coordinate system, one slit image on the vertical axis of the object and one slit image on the lateral axis of the object and one of the slit images on the vertical and lateral axes formed before and after the laser measuring unit is moved a predetermined amount in a direction of a camera optical axis relative to the object are taken into the camera, and the three-dimensional position is calculated from the relationship between the predetermined moving distance amount and the deviation of the slit images on the vision coordinates of the coordinate system. This method can be used to locate an electric adjustment position of an electronic component and to move the hand of an industrial robot carrying an electric adjustment member to the electronic component for adjusting the electronic component in the electric adjustment position.

A robot arm is provided with an end effecter for grasping an object and a force sensor for detecting a force acted upon the end effecter. In the state in which end effecter grasps an object, when there is a change in the force acting on the end effecter detected by the force sensor, outputted is a signal for releasing the force of the end effecter grasping the object. The object grasped by the end effecter can be taken out as if the object were handed from person over to person.

摘要:
A contour line characteristic point detecting apparatus arranged so that direction codes of respective tracing points are obtained by contour line data, and then, their directional difference values are found by a directional difference value calculating part. Thus, permutational direction codes are obtained through addition of the directional difference value at the tracing point, to the direction code at the tracing starting point or to the permutational direction code at the previous tracing point by an adder. Thus, by inputting this permutational direction code into a calculation table through delay registers of a plurality of stages, the linear component detection and corner detection can be effected without depending on the directions.
