In robot control, the coordinate system is very important. In Ros, the TF software library is used for coordinate transformation. Link: http://www.ros.org/wiki/tf/Tutorials#Learning_tf1. TF introduction we will introduce the functions of TF through a small instance. 1. Install the turtle package $ rosdep install turtle_tf rviz$ rosmake turtle_tf rviz2. Run the demo Run a simple demo: $ roslaunch turtle_tf turtle_tf_demo.launch Then we can see two turt

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

Dynamic Window Approach (DWA) is an important local trajectory planning algorithm, and the DWA algorithm is used in Ros to obtain good local path planning results. Here are some very good information.Resources:[1]. dynamic window method for local obstacle avoidance of robots (approach) (* * * *)[2]. Autonomous Robot Navigation[3].

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
