, the gateway is 192.168.1.254, the IP of the remote host Turtlebot is 192.168.1.103 Local host IP is 192.168.1.100 (NIC is eth0), The local host launches a Docker container named Rostest2 and configures it with a local IP of 192.168.1.97/24. Because the default mechanism of Docker is not required to provide a network for-DOCKER0, the--net=none parameter is used when the container is started by mirroring. The process is as follows:
(1) Launch a Docker
inside the Ros container
#ping 192.168.1.103
(3) Execute the roscore command inside the ROS container and execute successfully. When you need to execute other commands inside the container again, one thing to note is that you need to reopen a container's terminal window. With the EXEC command instead of attach, why not use the latter, open a try to know.
$ sudo docker exec-it
After entering the container, you still need:

Use the Xbox handle to control the car robot steps (take the Mrobot package as an example)
1. Install the Xbox360 handle driver
sudo apt-get install ros-indigo-joystick-drivers2. Test handle (general connection is JS0)
ls/dev/input/May be js0 One, it is possible to js0,js1 two, there may be js0-3 four, in the test can determine which of the handle
The first method:
Use JSTEST-GTK to test your handle

Before all the use of keyboard control Turtlebot walk, so want to write a paragraph code can let Turtlebot himself, after all, the future work is to let the robot on the map can achieve self-path planning to reach the designated destination.
After starting Turtlebot, in the command line Rostopic list We can see all the current topic, as shown below
We cmd_vel
In order to control Turtlebot's walk autonomously, we need to implement it in code. I. Preparation
In this process, we need to know which topic to send a message to. The internet says it's cmd_vel, but I didn't try. We can use the Rostopic list to see a listing of the current output activity topics. We can see that/cmd_vel_mux/input/teleop is what we need, the code is as follows:
young@young-lenovo:~$ rostopic List/capability_server/bonds/capability_server/events/cmd_vel_mux/active/cmd_vel_mux/i
