The Ros container in Docker is connected to the remote ROS host Docker is currently a popular open-source application container engine, and ROS (robot operating system) is a popular robotic operating system. In combination, it is a possibility to study the cloud robot. 1. P

It provides some basic tools for distributed computing, as well as programming the core parts of the ent

ROS Learning Series and ros Learning Series We have already discussed how to use URDF to build a robot car and display it in the simulation environment of Rviz, but the car is still. The following describes how to make it work in Rviz and clarify the relationship between URDF, TF and odom.1. Relationship between base_link, odom, fixed_frame, target_frame, and map

First, history With the rapid development and complication of the robot field, the requirement of reuse and modularization of the code is more and more strong, and some open source robot system can not adapt to the demand very well. 2010 Willow Garage released the open source robotic operating system Ros (robot operat

What's this?"Roomblock" is a robot platform consists of a Roomba, a Raspberry Pi 2, a laser sensor (RPLIDAR) and a mobile battery.The mounting frame can be made by 3D printers. ROS navigation system enable to make a maps of rooms and use it to reach to the goal autonomously.Who need this?Anyone want to learn the cutting-edge technologies of robotic navigation, mapping, and autonomous driving.

Using Ros for robot development, I think most companies want to use ROS to achieve the robot navigation, positioning and path planning, it has greatly reduced the development threshold of the robot field, developers do not have to take many detours to the predecessors, maste

This paper mainly introduces the configuration and use of navigation function package set. 1 Robot Setup Assuming that we have set up the robot in a specific way, the navigation feature pack set will make it available for movement. This configuration is outlined in the figure above. The white part is the required and implemented component, the gray part is optional and implemented , and the blue part is th

Of course, do not use this trick when there is no problem. The beginning of the section has been completed, the following is followed by Roswiki tutorial study. Roswiki is quite complete and friendly, the only drawback is that the Chinese version of the Cn-

Http://wiki.ros.org/ROS/EnvironmentVariablesRos/environmentvariablesIn ROS , you can set many environment variables. The most necessary to understand is ros_master_uri,ros_root and ros_package_path, because they are frequently used in systems and files.

This article only points out the differences between pal sde and Ubuntu 14.04. Configuration Requirements: We recommend that you use a computer with eight CPU cores. We recommend that you use a powerful graphics card with a resolution of at least X pixels for a better user experience when using visualizati
