In our previous blog, we used rviz to simulate turtlebot and used the urdf file to create our own robot smartcar. This blog is to combine the two, use the smartcar robot to simulate in rviz. I. Complete Models Previously, we used urdf file format models. In many cases, Ros does not support urdf files very well. Using macro-defined. xacro files has better compatibility and scalability. Therefore, we recompile the previous urdf file into a. xacro f

Recently, some netizens asked me on the internet how to configure the 3Com Switch. Because of the many questions, I guess this switch is more cost-effective, and there is a 3com 4200 3c17300a, so I will save his configuration code for you! Usage: 1. Save the following code to a file, for example, 3 comvlan. 2. Use the com line to enter the 3Com Configuration 3. Click the restore command to restore the file to the vswitch. Restart the file. Configuration File description: 1. After recovery, the I

If you have tried the previous example, there is no feeling that every time the robot to move and input instructions in the terminal, this is too cumbersome, there is no way through the keyboard to control the movement of the robot? The answer room of course. I studied several other robot keyboard control code, or some harvest, finally transplanted to the SmartCar, the experiment was successful. First, create a control pack First, we create a separate package for keyboard control: Roscreate-

published covariance over time, that is, the variance of the velocity. Note that the use of the world's observations will reduce the uncertainty of robot posture, but this is a positioning rather than a mileage meter. 3.3 Choice of time It is assumed that the robot pose filter has been recently updated at t_0 time. The node will update the robot pose filter until at least one measurement of each sensor arrives at a point in time after t_0. 4. Package Status 4.1 stability The code is well tested

Docker technology has been on fire a few years ago, and with the popularity of this year's devops, this technology has been sought after by the technology community. The mention of Docker is easily assumed to be a technology under the Linux platform. NET technology doesn't seem to matter to him, but it's a non-. NET core technology, and since the new push of.

Some Questions about learning How do I heat update mirrors (images)? (You can quickly start or destroy the container.) This time is almost real-time. How to hot update the game suit? The advantage is that the environment of each application is independent of each other, even if a container crashes will not affect other containers; How do you maintain each container using ports? (Method 1 is written in dockerfile, not flexible; Method 2 is specified at run time); That way, ther
