This paper studies the assembling technology of peg hole robot and searches its intrinsic regularity

for solving existing problems of peg hole assembling. The design theory and method on assembling technology have been studied

which can raise assembling efficiency and have widespread adaptability. By means of this method

the repetitive location precision requirement can be reduced. In the aspect of assembling high quality and small batch products of many variety

the robot assembling technology is gaining extensive application.
