The work aims to design an intelligent gatekeeper robot for property management of access to public places in the new situation, to help the construction of smart communities in the new era. Starting from the user needs, an AHP analysis was conducted to derive the weight values of each user need. The user needs were transformed into the technical characteristics of the product through QFD. A quality house of the product was constructed according to relevant attributes of user needs and technical characteristics. The absolute and relative weight values of each technical characteristic were calculated. The autocorrelation between each technical characteristic was determined to discover the possible conflicts in the design process. The conflict was described by applying the TRIZ theory, and the appropriate separation principle and invention principle were selected to solve the conflict and get the innovative solution of product design. Based on the results of the analysis and calculation of user needs and product technical characteristics and the application of TRIZ principles to resolve conflicts, the design of an intelligent gatekeeper robot was completed. The intelligent gatekeeper robot designed based on this design process can effectively meet the needs of two user groups of property management staff and the general public. The study provides a new idea as well as a reference for intelligent robots to help build a smart community.
