The method of computer-aided design oriented to requirement configuration is present for the palletizing robot. Index of design requirement is quantified hierarchically. The whole function of palletizing robot is decomposed according to the working plane. The various kinds of attributes of function carriers are digitized and the consistency is kept with the index of design requirement. Optimal design scheme can be gotten by the computation of evaluation function constructed in this paper. The software of computer-aided conceptual design for palletizing robot is developed.
