Abstract
The research status of industrial robot trajectory planning is discussed in detail, and the applicable occasions of cubic polynomial interpolation, quintic polynomial interpolation, B-spline curve, mixed polynomial interpolation and other methods commonly used in basic trajectory planning are comprehensively analyzed. At the same time, various methods of optimal trajectory planning for industrial robots are comprehensively reviewed. The advantages and disadvantages of various methods are compared and the important research direction of optimal trajectory planning is prospected.
Keywords: Industrial robot, trajectory planning, intelligent optimization algorithm, optimal trajectory
