摘要:

本文提出了一种三维几何求解方法,用于计算包括手部在内的7自由度关节臂的完整逆运动学。该方法被归类为具有几何解的解析方法,因为它在封闭的步骤数内获得精确解,将逆运动学问题转化为三维几何模型。为了简化问题,采用了运动学解耦方法,一方面利用手部姿态信息独立计算手腕位置,另一方面从手腕出发计算手臂其余部分的角度。

英文摘要:

This work presents a three-dimensional geometric resolution method to calculate the complete inverse kinematics of a 7-degree-of-freedom articulated arm, including the hand itself. The method is classified as an analytical method with geometric solution, since it obtains a precise solution in a closed number of steps, converting the inverse kinematic problem into a three-dimensional geometric model. To simplify the problem, the kinematic decoupling method is used, so that the position of the wrist is calculated independently on one hand with information on the orientation of the hand, and the angles of the rest of the arm are calculated from the wrist.
