Multidisciplinary collaborative optimization design of robots

The idea of multidisciplinary design optimization (MDO) is applied to synthesize optimum robots. The main idea and frame of collaborative optimization are introduced. Three disciplines of working stroke, driving performance and hydraulic component are involved in the design optimization of a 3-RRS robot. The optimization model of system-level and optimization model of subsystem are established. Sequential Quadratic Programming (SQP) and Genetic Algorithm (GA) are respectively used to execute the optimization of system-level and the optimization of subsystems using popular commercialized MATLAB. The numerical results indicate that the collaborative optimization can be successfully applied to dealing with the complex robot system, and lay a foundation to solve more complex mechanical system.
