Configuring Linux systems to support industrial robots and automated production development
With the rapid development of industrial robots and automated production, more and more companies are beginning to use Linux systems to support their production development. Linux system has good stability, flexibility and customizability, which makes it an ideal choice. This article will describe how to configure a Linux system to support industrial robots and automated production development, and provide some code examples.
sudo apt update
sudo apt upgrade
ROS (Robotic Operating System): An open source platform for robot development. Run the following command to install ROS:
sudo apt install ros-melodic-desktop-full
Gazebo: An open source tool for simulating robotic environments. Run the following command to install Gazebo:
sudo apt install gazebo9
Python and pip: used to write and manage Python scripts. Run the following commands to install them:
sudo apt install python3 python3-pip
echo "source /opt/ros/melodic/setup.bash" >> ~/.bashrc
source ~/ .bashrc
Next, you can create a ROS workspace to organize your project code. Open a terminal and run the following command:
mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/
catkin_make
First, create a Python file named "talker.py" and copy and paste the following code into In the file:
#!/usr/bin/env python import rospy from std_msgs.msg import String def talker(): pub = rospy.Publisher('chatter', String, queue_size=10) rospy.init_node('talker', anonymous=True) rate = rospy.Rate(10) while not rospy.is_shutdown(): hello_str = "hello world %s" % rospy.get_time() rospy.loginfo(hello_str) pub.publish(hello_str) rate.sleep() if __name__ == '__main__': try: talker() except rospy.ROSInterruptException: pass
Save the file and run the following command to make it executable:
chmod x talker.py
Next, open a terminal and run the following command to start ROS node:
roscore
In another terminal, run the following command to run the "talker.py" node:
rosrun 8c407fc3ca5bd2960ccd7d76fd924a9e talker.py
In this way, you create a ROS node and start publishing messages on the "chatter" topic.
The above is a simple example, you can write and run more complex ROS nodes according to your own needs.
Summary
Configuring a Linux system to support industrial robots and automated production development is a relatively simple process. You just need to choose a suitable Linux distribution, install the necessary software packages, and perform some basic configuration. Additionally, ROS provides a powerful platform to develop and manage robotic applications. I hope this article is helpful to you and can provide guidance for your industrial robot and automated production development.
