message publishing under the command line. Now we need to convert these commands into python code and encapsulate them into a single node. For the previous command line, we can easily write the following control code in the smartcar_teleop/scripts Folder: #!/usr/bin/env pythonimport roslib; roslib.load_manifest('smartcar_teleop')import rospyfrom geometry_msgs.msg import Twistfrom std_msgs.msg import Stringclass Teleop: def __init__(self): p

In order to control Turtlebot's walk autonomously, we need to implement it in code. I. Preparation In this process, we need to know which topic to send a message to. The internet says it's cmd_vel, but I didn't try. We can use the Rostopic list to see a listing of the current output activity topics. We can see that/cmd_vel_mux/input/teleop is what we need, the code is as follows: young@young-lenovo:~$ rostopic List/capability_server/bonds/capability_s

simulations, we used a message release at the command line, and now we need to convert these commands into Python code and encapsulate them in a separate node. For the previous command line, we can easily write the following control code under the Smartcar_teleop/scripts folder: #!/usr/bin/env python import roslib roslib.load_manifest (' Smartcar_teleop ') import rospy from geometry _msgs.msg import Twist from std_msgs.msg import String class
