Ros,gazebo and Rviz startup and environment Setup issues

In the Linux-based Ros, it is important to note the environment variables, as follows: The activation of ROS gazebo and Rviz.

Rosed baxter_tools enable_robot.py uses the default way to open the above. py file, which is opened in the desktop. BASHRC, for example, you can use export editor= "emacs" This represents a new window, or you can use "EMACS-NW" to indicate that it is not a new window. Also, modify the BASHRC original window to source. BASHRC; The newly opened window is available.

./baxter.sh Sim This is similar to a distributed form of command, which should be executed before execution

Roslaunch Baxter_gazebo <tab>
Rosrun Rviz Rviz

Rostopic Echo/robot/joint_states This is the real-time display of its joint state.

Ipython is an upgraded version of Python with auto-complete functionality

For the need to monitor their joint variables, the robot first needs to be moved, which is the need to use the. py file in the baxter_examples to run;

Then open the Rosrun rqt_plot rqt_plot in a new window to open the drawing window


Enter Rosnode list in the new window to see the node currently running
To see the topic of its output, the Rosnode Info/rsdk_joint_velocity_wobbler

You can select the topic, use the Rostopic echo/robot/limb/right/joint_command to view the data in it, and add it in plot, but this should be an array

/robot/limb/right/joint_command/comand[0] To view the graphics/robot/limb/right/joint_command/command[0], you can first perform the Grapefruit addend Group, And then enter Comman[0]

For the method to start Gazebo:
Should be first entered into./baxter.sh Sim, and then Roslaunch Baxter_gazebo <tab>, and can run Rosrun Rviz Rviz;

For the method to start Rviz:
The first should be roscore (this is because using Rosrun cannot start Roscore), then./baxter.sh Sim, and Rosrun Rviz Rviz. It is worth noting that sometimes it is necessary to source/devel/setup.bash to set environment variables.

At the same time several website about robot can be concerned: Kawasaki Japan Kawasaki, Fanuc (Japan); Kuka Kuka (Germany); ABB (Switzerland); Aldebaran al-Great Britain (Paris, France) produced Nao.
ROS IDEs (exprience and advice on using integrated development environments with ROS) Here are some examples as well as eclipse.

For some software that studies Ros: Edmodo,github and so on.

Cal-y can display date time

Since Firefox is a command written using a shell script, you can directly Firefox www.bing.com/

You can use evince to open PDF files in the current directory, such as Envince test.pdf, and you can use an absolute address to open the appropriate PDF.
