针对手把手示教喷涂机器人再现运动不平稳、整体运行速度低等问题
提出了一种基于样条曲线拟合和运动规划的优化方法。通过使用非均匀B样条曲线对示教轨迹进行拟合计算
得到位姿拟合曲线。位置曲线和姿态曲线是分开进行离散化的。位置曲线基于S型加减速进行离散化
减速点的寻找采用双向插补的方法。姿态和位置的同步问题
采用建立姿态曲线参数与位置曲线参数的映射关系解决。通过仿真和实验验证了该算法能够有效地提高示教机器人再现运动的平稳性和运行速度。
In view of the unsteady motion and low overall running speed of the hand by hand teaching spray robot
an optimization method based on spline curve fitting and motion planning is proposed. By using the non-uniform B-spline curve to fit the teaching track
the position and attitude fitting curve is obtained. The position curve and attitude curve are discretized separately. The position curve is discretized based on S-type acceleration and deceleration
and the two-way interpolation method is used to find the deceleration point. The problem of attitude and position synchronization is solved by establishing the mapping relationship between the parameters of attitude curve and position curve. Simulation and experiment show that the algorithm can effectively improve the stability and running speed of the teaching robot.
