Optical indexing system

摘要

A T.V. camera, mounted on the arm of a teleoperator remotely controlled grasping hand, is used to view an object to be grasped through an in-line semi-reflective mirror and a laterally disposed reflective mirror. Alignment of the teleoperator with the object is indicated by a single superimposed image of the object on the television viewing screen. Non-alignment of the teleoperator hand and the object is indicated by double images.
