Is there any robot with which 2D navigation stack is already setup in case of Gazebo And we can send robot to a particular location through rviz or simple_navigation_goals

Is there any socket communication involved between Gazebo and ROS

How much difficulty we have to face to create a maze environment?

Many thanks.

I found some robots like Robotino and TurtleBot (http://wiki.ros.org/Robots/TurtleBot). But someone says that they can't be properly launched in Gazebo. I don't know it's truthness. Again, for Robotino, lots of packages are mentioned here, but how to install it on ubuntu 10.04 (ROS fuerte is present)?

Socket communication is present in Gazebo-Ros.

I've launch TurtleBot in Gazebo 1.9 under hydro and ran with move_base. But odometry does not use the joint PID controllers. Also because there is no single URDF I could not find the joints , it may not use cmd velocity for 2W dead reckoning. I think Stage may be better for a maze.

Nice to know that you have achieved high level navigation through TurtleBot. Does rviz window helps us to navigate automatically? Since I am new to Gazebo, I don't know about joint PID controllers. Does the problems you have mentioned create sub optimal behavior during navigation. Again in Gazebo I find something [here](http://wiki.ros.org/hector_nist_arena_worlds), don't know it's usefulness in maze creation. Thanks buddy.

Rviz lets you set Pose and Goal. I think you should be able to use a teleop to navigate if you override the cmd_vel topics. The ros gazebo PID controllers are suppose to be realistic motor simulators using hardware interface. But I have had little success with this so far.

Using UsarsimROS, I am able to achieve teleop for P3AT, but now I want to switch it to Gazebo, because many people said that turtlebot and PR2 already have 2D stack properly tuned without even touching single line of code. But right now I can't decide whether TurtleBot and PR2 really achieves high level navigation or not?

Which one of the tutorial s you have followed; first one is (http://wiki.ros.org/Robots/TurtleBot) and second one is (http://wiki.ros.org/turtlebot_simulator) .
