PS3 Joystick 5. 1 MegasOros 2 yr. ago Good answer, as a side note, a good place to start is to go through the launch file you use in a tutorial and figure out exactly what commands you are running / nodes you're starting. Then get data from joystick and do some calculations based on them and then send command velocities to the turtlebot. Navigating. time to connect to Gazebos model database. Now you can launch your world: In the next lessons we will use this command: with the default world /opt/ros/indigo/share/turtlebot_gazebo/worlds/playground.world. Publications: You are done with Simulation section. In this case you use the Ethernet, however, in many cases the wireless (wlan) is the appropriate connection. Run the navigation demo. An example of ipconfig is shown. First, bring up the TurtleBot simulation as described in the Gazebo Bringup Guide. corot Merge pull request #78 from oscar-lima/fix-tf-problem. 1 2 3 3 Dear friends, I am very new in ROS and I have a problem that I cannot solve. In this video I will show you how to have a Turtlebot 3 simulation in Gazebo with ROS running in a few minutes, by using any type of computer and requiring no ROS nor Gazebo installation. to update its model database.
