This paper investigated the characteristics of joint space and operational space of the robot for the machine layout optimization problem in robot workcell. The sum of trajectory distance of each joint as an evaluation function is a more accurate approximation of the robot cycle time and power consumption. Adaptive-differential evaluation as a simple and efficient algorithm was introduced to improve the computa- tional efficiency. A typical industrial case was used to verify the validity and practicability of the proposed algorithm. The simulation result shows the effectiveness of the proposed method and the advantage of the joint space evaluation.
