码中一个SDH表定义的构型似乎有问题,但是对后面的计算并没有影响,后面的计算中并没有访问dh表中的d和a参数 如下图所示6dof_kinematics.cpp文件中tmp_DH_matrix定义的SDH构型 将上面的构型用matlab绘制出来如下图所示 ` % 清除环境 clear all; close all; clc;
% 注意:Link的参数顺序为 [theta d a alpha] L1 = Link([0 0.550 0.180 -pi/2]); L2 = Link([-pi/2 0 0.680 0 ]); L3 = Link([pi/2 0.165 0 pi/2]); % L3 = Link([pi/2 0 -0.165 pi/2]); % L3的DH参数应该定义成这样 L4 = Link([0 0.842 0 -pi/2]); L5 = Link([0 0 0 pi/2]); L6 = Link([0 0.12 0 0 ]); % 创建机器人模型,将所有链节按顺序组合 SDH_robot = SerialLink([L1 L2 L3 L4 L5 L6], 'name', 'SDHRobot'); view(3)
% SDH_robot.plot([0 0 0 0 0 0]);
% 设置机器人绘图参数(可选) SDH_robot.display
SDH_robot.teach([0 -pi/2 pi/2 0 0 0]);` D_ELBOW参数和示意图中描述的不同 启用上面matlab代码中的注释,将L3定义为 L3 = Link([pi/2 0 -0.165 pi/2]); 虽然对后面的计算没有影响,应该定义为
