To use the Nav2 stack and slam_toolbox correctly, we will need to change the DDS implementation used by ROS2. Don’t worry too much, the setup will be super simple. The thing is, as you may know, ROS2 is based on DDS for the middleware. There are different DDS implementations, the...
ROS2 Nav2 – Generate a Map with slam_toolbox In this tutorial I will show you how to create a map for the Nav2 stack, using the ROS2 slam_toolbox package. We are going to use a simulation of a robot, the Turtlebot3, but all the steps that are related to SLAM can be replicate...
Let's create a project for multiple robots, and make sure we can visualize them both in RViz and Gazebo! Let's also make Nav2 algorithms work with them. Navigation: examples Creating map from an image, ROS2 Nav2, Waypoint Follower, Navigating with Keepout Zones, Navigating along given pat...
Another method involves leveraging SLAM technology. The trajectory generated by SLAM, utilizing sensors such as LiDAR, camera, and encoder, can serve as an additional reference for ground truth, especially in environments where GPS signals are unavailable. Combining the strengths of both GPS and SLAM...

In order to do that I needed a map or I needed to create a map dynamically by running SLAM. The PR2 has an existing ROS package to run navigation and SLAM together, pr2_2dnav_slam, which made it simple to get those algorithms running. With those packages running, I opened RViz the ...
. SLAM is not unique to just classical systems. It is accomplished, in some similar form, by rodents by use of their hippocampus [2,19–21]. The special neurons or brain cells which accomplish this will be covered in Section3. 2.2. Fundamental Navigation Issue: Sensor Error...
roslaunch magni_nav move_basic.launch while roslaunch magni_nav aruco.launch was already running and then i selected a simple 2D goal in rviz and the magni starts rotating on itself and starts moving kinda straight ahead for some time (till a wall would basically stop it). I struggle to ...
