编程实现PUMA 560机器人模型的创建、模型图输出和变换矩阵的计算

以下是Python语言实现PUMA 560机器人模型的创建、模型图输出和变换矩阵的计算的示例代码：

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

# PUMA 560机器人的DH参数
a = [0, 0, 0.4318, 0.0203, 0, 0.150]
alpha = [np.pi/2, -np.pi/2, 0, np.pi/2, -np.pi/2, 0]
d = [0.1662, 0, 0.4318, 0, 0.019, 0]
theta = [0, 0, 0, 0, 0, 0]

# 创建机器人模型
def create_robot_model(a, alpha, d, theta):
    n = len(a)
    T = np.eye(4)
    T_list = []
    for i in range(n):
        Ti = np.array([[np.cos(theta[i]), -np.sin(theta[i])*np.cos(alpha[i]), np.sin(theta[i])*np.sin(alpha[i]), a[i]*np.cos(theta[i])],
                       [np.sin(theta[i]), np.cos(theta[i])*np.cos(alpha[i]), -np.cos(theta[i])*np.sin(alpha[i]), a[i]*np.sin(theta[i])],
                       [0, np.sin(alpha[i]), np.cos(alpha[i]), d[i]],
                       [0, 0, 0, 1]])
        T = np.dot(T, Ti)
        T_list.append(T)
    return T_list

# 输出机器人模型图形
def plot_robot_model(T_list):
    fig = plt.figure()
    ax = fig.add_subplot(111, projection='3d')
    ax.set_xlim3d(-0.5, 0.5)
    ax.set_ylim3d(-0.5, 0.5)
    ax.set_zlim3d(-0.5, 0.5)
    ax.set_xlabel('X')
    ax.set_ylabel('Y')
    ax.set_zlabel('Z')
    ax.view_init(elev=30, azim=30)
    for T in T_list:
        x = T[0, 3]
        y = T[1, 3]
        z = T[2, 3]
        ax.scatter(x, y, z, color='r', s=20)
    for i in range(len(T_list)-1):
        T1 = T_list[i]
        T2 = T_list[i+1]
        x = [T1[0, 3], T2[0, 3]]
        y = [T1[1, 3], T2[1, 3]]
        z = [T1[2, 3], T2[2, 3]]
        ax.plot(x, y, z, color='b')
    plt.show()

# 计算机器人末端执行器的变换矩阵
def get_end_effector_transform(T_list):
    T = np.eye(4)
    for Ti in T_list:
        T = np.dot(T, Ti)
    return T

# 测试代码
T_list = create_robot_model(a, alpha, d, theta)
plot_robot_model(T_list)
T_end = get_end_effector_transform(T_list)
print('机器人末端执行器的变换矩阵：\n', T_end)

运行上述代码，可以得到PUMA 560机器人模型的图形和机器人末端执行器的变换矩阵。

注意：上述代码中的DH参数是根据PUMA 560机器人的标准参数进行设置的。如果使用的是其他机器人的参数，需要根据实际情况进行调整。
