The method of computer-aided conceptual design is present for the palletizing robot. Intelligent design and modeling are integrated in this system. Index of design requirement is quantified hierarchically and various kinds of attributes of function carriers are digitized. The analytic hierarchy process is used for reference to check the consistency of quantitative value of attributes and the rationality is ensured. Design requirement can be configured flexibly in man-computer interaction module and the optimal scheme is generated automatically according as the computation of evaluation function. Model file of virtual prototype for ADAMS can also be generated automatically by auto-modeling module. Software system of computer-aided conceptual design for palletizing robot is developed based the method mentioned above.
