So we are now downloading from the ros.org package: Http://www.ros.org/browse/list.php?package_type=packagedistro=fuerteNote that the above packages need to be downloaded in Ros workspace.2.

average speed of 500 K, and Max-Limit = 3000000/3000000 is the normal speed limit of 3 m! Note that many of the experts in the Network Alliance have mistaken the ROS algorithm.

1, first install the opencv-3.20 under Linux, want to see a blog. 2, OpenCV installed, in the Ros under the compiler to use OPENCV library function files, always appear below the error, or similar, is Ros find OpenCV library function, the solution is that we can add ourselves. CMAKEFILES/BUTTON.DIR/SRC/BUTTON.CPP.O: In function ' main ':/home/liuqiqi/dev/dobot_ws/src/opencv_image/src/button.cpp : 75: Refere

Combination reason: The Ros need to use the OPENCV3.0 library function (and the library in the Opencv_contrib), but also must use the Cv_bridge conversion. However, it is found that the binary installation Ros-*-cv-bridge requires a bundled installation of OPENCV2. Workaround:git Download the latest version of the source code, self-compiled installation .Harvest: Deep understanding of the source installati

To prevent L2 routing, wayos can be implemented through the simple dial King client. I also described this (Ros can also be used). Next I will explain a simpler method of ROS: Overview: You can set the TTL value to prevent L2 routing. Principle: TTL is a value in the IP protocol package. It tells the network whether the packet is discarded because the time in the network is too long. There are many reasons

During the simultaneous operation of the two machines, the TF transformation of ROS requires that the clocks of the two machines be kept in accordance with one another.1. Query timeFirst, look at the difference between the two machine clocks with the following command. On this computer, view the machine time of the remote master:Ntpdate-q other_computer_ipFor example192.168. 0.23Or you can query the time of the machine by entering the date command dir

In my opinion, the most powerful place of ROS is its communication mechanism, not only the communication between the process is convenient, even the communication between different devices is also very convenient, just add a few lines of code, you can realize the Topi C sharing, remote control and other functions between multiple computers. Let's do it together!This assumes that we have two computers: computer A is the host side, and computer B is the

　　Kinect for Xbox One (v2) uses time flight technology to greatly improve the performance of deep images, compared to the Kinect for Xbox v1, which acquires depth through structured light. The original image color image provided by the Kinect for Xbox (v1) is 640x480, and the depth map is in the range, and under Ubuntu, you just need to install the Openni to get the registered color map and depth map. While the Kinect for Xbox One (v2) original color image is 1920x1080, the depth image is 512x42
