n this paper,a detailed study of the theoretical modelling of robotic assembly workstation is presented.

Through analyzing and expounding the system concepts and composition,the flexible assembly workstation prototype for major-parts assembly was set up.

The robotic workstation layout is the main part of the design for a flexible robotic assembly sys-tem.

The present assembly line balancing methods lack associativity,systematic features and integrity and fail to take into consideration of the problems such as workstation allottment of mixed-model assembly line,ordering and the restrictions of practical applications except for the ordering of technologic procedures by the punishment function.
