Method for designing special function robots

A method for designing a customized robot to perform a specified function begins by initially creating an electronic library of data about modules and accessories for a robot assembly. The library stores, for each module and accessory, at least firmware for operation and dimensions. Per robot, the method includes receiving a set of functions and requirements of the customized robot, generating design(s) for the customized robot by finding a set of modules or accessories which match at least one of its functions and requirements, based on information in the electronic library, performing a set of validation tests of each design against criteria, identifying the design(s) which passed the set of validation tests, and generating a list of modules and accessories of a selected design and a connection map for the selected design indicating how the modules and accessories are to be connected together to form the customized robot.
