This paper explores the coincidence assembly recognition of two objects of any shape in any designated position within a three dimensional space. A mathematical model based on algebraic topology theory is presented. The objects are regarded as envoloped with 2- simplexes which are convex in shape. Then the coincidence recognition for the two objects can be reduced to an assembly of a mutually correspondent 2-simplex on the two objects. An algorithm is proposed for coincidence assembly with a computer zztomatic coorperative control, which eliminats the need for vision aid. This algorithm is straightforward and involves the least amount of computing ever proposed for such an operation. This algorithm has been simulated using Pascal language on an IBM-PC microcomputer.
