| 摘 要： | 为实现机械手作业轨迹平滑,关节轨迹的速度、加速度、加加速度保持连续,起始和停止的速度、加速度和加加速度可以任意配置,采用5次B样条曲线插值方法构造关节轨迹。推导了B样条曲线插值轨迹算法;通过VC++6.0开发平台,基于MFC框架类和OpenGL图形库仿真出机械手的运动过程,并绘制出各关节的位置、速度、加速度时间曲线图。仿真结果表明,该方法使机械手关节调整平滑且运动平稳,运动性能显著优于传统的三次样条轨迹规划。 |

| Abstract: | An interpolation method based on five degrees B-spline for manipulators trajectory planning in joint space is proposed to accomplish smooth trajectory adjustment.The B-spline interpolation algorithm can ensure the continuous of velocity,acceleration and jerk in joints moving process,also can achieve start and stop velocity,acceleration and jerk be any configuration.The manipulator trajectory is simulated out and the graphs of joints position-time,velocity-time and acceleration-time are draw n out through C + + 6.0 development platform based on MFC framew ork class and OpenGL graphics library.Simulation results show that,the proposed algorithm supplied manipulators w ith smooth adjustment of trajectory and stable movement of joints. |
