Do i need to add the static TF transformation information to the launch file? I'm using ROS and a RPLidar A2 and apparently the sensor turns clockwise which means its reference frame (see image below) isn't the same as a normal cartesian frame (x axis on 0, y axis on 90). Contribute to ROBOTIS-GIT/turtlebot3 development by creating an account on GitHub. the new laser is recognized but not included in my old environment for my python program, so I figured it was the location of the files for the new laser. Try changing the frame, you can try world or maybe base_link. This works quite well for quick and easy transforms, however, it doesn't scale when many sensors and frames get added in. Regarding point 1) If I understand correctly, I should copy the contents of the ZIP file into the catkin working directory src. To be on the safe side, I first reset the image to my previous state and then started the installation from Create a Catkin workspace. The ROS Wiki is for ROS 1.
