After using Rspberry pi, learn about Ros as an open-source robotic operating system.The earliest use of raspberry Pi 2B +raspbian Jessie successfully installed with the source of Ros Indigo, and then change the RaspberryPi3, try again on how unsuccessful.Later, no matter, looking for a transplant raspberrypi 3B Debian 9 arm64 method, successfully run a 64-bit system.Because it is Debian 9 (stretch),

to modify your own. ⑥cmake according to what generate makefile it. It is also based on the CMakeLists.txt file to generate makefile, the CMakeLists.txt. We should be more familiar with it, that is, we create a new software package automatically help us generate. ⑦ the Last Catkin_make is the compilation of CMake and make a package of instruction tools, standardize the work path and the path to generate files, And when creating a new workspace, we create a top-level CMakeLists.txt file that recu

Perform execution in the workspace directory Catkin_make The following directory structure is available after you use the Catkin_make command.3, in the SRC directory to establish the package:Using the catkin_create_pkg command, create a package under the SRC directory, as shown in the following example: Catkin_create_pkg beginner_tutorials std_msgs Rospy roscpp The last generated file directory structure is as follows: The

But the long test results are as follows: The horizontal axis of the ROS receives the number of event, in 40000 units. (x, Y) indicates that when Ros receives the x*40000

We have explained a lot about PPPoE settings, such as PPPoE settings in Windows and PPPoE settings in Linux. In the next few days, we will mainly explain how to set up the ROS soft route PPPoE. ROS soft route PPPoE settings: Set the IP address pool Go to winbox and click IP ingress Pool1 ｡ Figure 1 On the "IP Pool" page, click "+" at the bottom of the menu, as shown in figure 2 ｡ Figure 2 On the "

Demand Sometimes we need to have a few different master, they want to exchange topic content, this time cannot use Ros to set the same master method. Our approach is to construct a client and a server, they run under different master, the client subscribes to Topic1 under Master1, and then through the TCP protocol (it defines a message protocol format) Send to the server below Master2, for message parsing, and then release the topic1 below Master2, so

First, migrate the C + + Boost Library:1. First go to the Boost website to download the latest boost version, I downloaded the boost_1_6_0 version, unzip.2. Go to the Unzip directory: CD Boost_1_6_0, execute the following command:$./bootstrap.sh--prefix=path/to/installation/prefixThe value of prefix is the path where you want to install boost, and the default is to install it under/usr/local if you do not turn on this parameter. I am installing in the/home/xzz/boost_1_56_0 directory:$./bootstrap

This article describes the format of the Laserscan message and the meaning of each parameter, and at the end of the article wrote a subscriber to read the laser data. Laserscan is a Ros-defined laser data format, and the message is defined in the Sensor_msgs/laserscan.msg file with the path:/opt/ros/indigo/share/sensor_msgs/msg. An example of the Laserscan message is as follows: header:seq:101732 stamp:secs
