摘要
机器人操作臂工作空间的形状和体积的精确计算对于其优化问题是非常重要的。为此首先根据从关节空间到工作空间的运动映射关系,使用蒙特卡洛方法产生由点组成的三维机器人工作空间。然后,通过把这些点分解成一系列的切片,获得机器人工作空间每层的二维边界曲线;基于切片曲线,由三维重构的方法产生边界曲面。最后,用数值积分的方法计算了机器人工作空间的体积。
Exact computation of the shape and volume of robot workspace is very important for its optimum design. Firstly, Monte Carlo method is used to generate the three - dimensional (3D) robot workspace composing of points, according to the kinematics mapping from the joints space to the workspace. Then the two - dimensional (2D) boundary curves of each layer of the workspace are obtained by classifying these points into a series of slices. The boundary surfaces are generated by 3D reconstruction method based on the slices curves. Finally, the numerical integration is adopted to calculate the volume of the workspace.
