Abstract : This paper reports an experimental investigation of the application of visual feedback to a simple computer-controlled block-stacking task. The system uses a vidicon camera to examine a table top containing two cubical blocks, generating a data structure which is analyzed to determine the position of one block. An electric arm picks up the block and removes it from the scene, then after the program locates the second block, places the first on top of the second. Finally, the alignment of the stack is improved by analysis of the relative position error as seen by the camera. (Modified author abstract)
