There are multiple variations of generating triangle using numbers in Python. In this case, you use a for loop to draw five lines on the image.

The beginning image starts at (0,0) in the first loop.

This tutorial teaches you how to rotate your turtle. import turtle wn = turtle.

import turtle.
node_name, log_level=ros.
The code above imports rospy (ROS library for Python), Twist (for us to work with the linear and angular velocity of the turtle), and sys (library that enables us to pass parameters via the Linux command line).

节点之间通过主题（topic）、服务（services）、动作（actions）或参数（parameters）等方式进行通信。.

That is why we will be controlling the turtle.

. Here we'll use rqt_plot to plot the data being published on the /turtle1/pose topic. (since publishing a message does not do the job) It doesn't actually do the job but that's how you can send easy instructions.

3. ws = turtle. Thus, as shown in the figure below, from a square near the middle of an empty chessboard, the knight (labeled K) can make eight different moves (numbered 0 through 7). Install the turtlesim package for your ROS 2 distro: Linux. The idea is to import Twist from geometry_msgs.
