Abstract
A robotic system for grasping a randomly oriented object, comprising grasping means for grasping said object is disclosed. Motor means places the grasping means at a desired position and causes performance of a gripping function. Camera means forms a first image of the object. An optical train conveys an image from a predetermined point to the camera means, the predetermined point being fixed relative to the grasping means. Image means contains a second image of the object to be grasped. Comparison means compares the first image to the second image. First coupling means couples the image means to the comparison means. Second coupling means couples the output of the camera means to the comparison means. Image rotation means causes rotation of the second image with respect to the image produced by the camera means. The comparison means is responsive to the first and second coupling means to stop rotation of the image rotation means when a coincidence in angular position is detected between the second image and the image produced by the camera means. Finally, angular orientation means generates an angular orientation signal in response to a detection of coincidence between the second image and the image produced by the camera means to generate an orientation signal indicating the orientation of the object and providing the orientation signal to the motor means to angularly orient the grasping means with the object to be grasped.
