需求:
在txt文档里写了一串机械臂运动的点,里面包含了xyz位置和四元数组,有n行,每行n个数据,需要将这些数据用rostopic发布出来,让机械臂依次运行这些点
代码:
#!/usr/bin/env python
import roslib
#roslib.load_manifest('learning_tf')
import rospy
import math
import tf
import geometry_msgs.msg
import turtlesim.srv
import sys
import time
import json
import string
from geometry_msgs.msg import PoseStamped
i = 0
def txt_read ():
test_pose = PoseStamped()
global i
f = open("SamplePoses.txt","r")
lines = f.readlines()
pose = [0.0,0.0,0.0,0.0,0.0,0.0,0.0]
for line in lines:
pose = line.split()
print(pose[0])
test_pose.pose.position.x = float(pose[0])
test_pose.pose.position.y = float(pose[1])
test_pose.pose.position.z = float(pose[2])
test_pose.pose.orientation.x = float(pose[3])
test_pose.pose.orientation.y = float(pose[4])
test_pose.pose.orientation.z = float(pose[5]

该代码读取TXT文件中的机械臂运动点数据,包括xyz坐标和四元数信息,然后利用rostopic将数据转化为PoseStamped消息并发布,以控制机械臂按顺序执行动作。
