With uour help I have replaced my Dynamixels AX-12A with XL430-W250-T motors.
The motors sw#1 & sw#2 tests are working.
The RVIZ segmentation fault problem has been resolved bij using another laptop.
So I am continuing my Turtlebot3 journey.
INow I am stuck because I am using another lidar other than the one used with Turtlebot3-burger.kit.
My lidar is the YDLIDAR X4.
Looking at the error-output of the command "roslaunch turtlebot3_bringup turtlebot3_robot.launch" , I assume it is because the mismatch in the lidar hardware.
Can you help me to make my Turtlebot3-burger working with the YDLIDAR X4?
I appreciate your help in this,
Thanks and best regards,
I can see that you are still using the "hls_lfcd_lds_driver" which is the default hardware lidar driver for TurtleBot3.
Although I haven't used your lidar, I think you should use proper driver for your YDLIDAR X4.
You might want to check out the ROS community to see if there're any similar cases and possibly more experienced users for customizing TurtleBot3.
