Thank you so much for your great help. Now I am trying to build my own ROSject and practice the machine learning course again from scratch. My question is the simulation in ROSjest doesn’t have a gazebo world with a wall for turtlebot2. May I please ask if you can update the simulation options for ROSjest or Could you pls tell me how I can add a wall myself?
My second question is I’ve noticed most of the course have been updated to ROS neotic. How do you think I can access the older version of ROS in 5 days course for kinetic? I prefer that version of the course.
Thanks a million. You are the legend
