Navigation and positioning are important parts of Robot Research.Generally, a robot needs to use a laser sensor (or a depth sensor to convert it into a laser data) in a strange environment, first modeling a map, and then performing navigation and positioning based on the created map. There are also many complete packages in ROS that can be used directly.In

If I tried the previous example, is it too troublesome to input commands to the terminal every time the robot moves? Is there a way to control the robot's movement through the keyboard? Answer room of course. I have studied several other robot keyboard-controlled code, but I still have some gains. I finally transplanted it to smartcar, and the experiment was successful.1. Create a control package first. Cre

Summer vacation at home is a little slack, no, very slack--|! My conscience hurts and I want to make up the progress. But I suddenly find that I have been interrupted for a while, and I have forgotten some of the most basic symbols.
This time, we made a very basic task, restoring the previous progress.

The difference between the single quotation mark ' and ' in the Ros command, such as using the ' single quote ', is correct for the following commands:$ rosrun Rviz rviz-d ' rospack find Rbx1_nav '/sim.rvizInstead of using ' single quotation marks, the following commands are wrong:$ rosrun Rviz rviz-d ' rospack find Rbx1_nav '/sim.rvizThe command can execute and start Rviz, but it cannot be indexed to the corresponding. rviz file, so the corresponding

Ros is a new super-portable robot programming system. Active Oxygen allows you to easily build distributed robot control systems on different languages and platforms.

Docker's existing network model is simple, scalability and flexibility do not meet the needs of many complex scenarios, most of the time users need to customize the Docker container network, rather than using Docker created by default IP and NAT rules.
