摘要
针对工业机器人作业单元布局优化问题,研究了机器人关节空间和操作空间的特性.将机器人的关节轨迹距离作为评估指标,使得机器人的周期时间和功耗的描述更为准确;采用简单、高效的自适应差分进化算法,提高了计算效率.对典型机器人作业单元的布局优化实例进行研究,结果表明了算法的有效性和关节空间评估指标的先进性.
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.
