[ros-users] Gazebo and ROS

Hi



I am trying to run some robot simulations with Gazebo in ROS and I have a
few basic questions.



Is there a Pioneer model in ROS (or do we need to create our own?)



I am used to control the robot in Gazebo through Player, I am just wondering
what is the equivalent in ROS? How can I subscribe to the position
controller of the robot and move it around manually?



Is there a camera sensor/interface/controller that I can attach to a robot
and I can subscribe to? (I’ve read something about Rviz but I am not sure
how to get it working)



How can I attach custom behavioural/navigation code to the robot so it
explores the world by itself based on the code? And want languages does ROS
support?



Thanks you very much.


Regards,

Amy
