Lets say I start turtlebot up in the willow garage world as shown in: http://answers.ros.org/question/12956/running-turtlebot-simulator-in-willow-garage-world

Is there a way to simulate the Kinect PointCloud data that world would produce, so I can see it in rviz?

Best Regards,

Hi,

The "Visualizing TurtleBot Kinect Data" tutorial http://www.ros.org/wiki/turtlebot/Tutorials/Looking%20at%20Camera%20Data seems very tided to the TurtleBot - is there a way to visualize the Kinect Camera or PointCloud in rviz without the TurtleBot?

Best Regards,

As outlined in: http://www.ros.org/wiki/pr2_simulator/Tutorials/WorkingWithGazeboOverRos

It fails to make pr2_teleop:

cole@z:~$ rosmake pr2_teleop
[ rosmake ] Packages requested are: ['pr2_teleop']                              
[ rosmake ] Logging to directory/home/cole/.ros/rosmake/rosmake_output-20111129-103822
[ rosmake ] Expanded args ['pr2_teleop'] to:

[ rosmake ] WARNING: The following args could not be parsed as stacks or packages ['pr2_teleop']
[ rosmake ] ERROR: No arguments could be parsed into valid package or stack names.

Any ideas?

I'm using ros-electric in Ubuntu 11.10

Hi,

I would assume ROS can run in pure simulation? I'm trying to build a SLAM map of simulated environment while navigating through it (with path planning and obstacle avoidance) using the simulated TurtleBot. However most of the TurtleBot tutorials assume you have the TurtleBot hardware.

FYI, I've already got the TurtleBot simulator working via:

roslaunch turtlebot_gazebo turtlebot_empty_world.launch

However I'm unsure how to:

1. calibrate the simulated TurtleBot
2. see the output of a simulated Kinect
3. see the output of SLAM (and ideally the particles in the particle filter)
4. see the output of the path planning
5. drive the robot around (or set way points)

FYI, I would of thought I could do (5) via

roslaunch turtlebot_teleop keyboard_teleop.launch

But it doesn't move the TurtleBot in the simulator - I assume its for the real hardware only?

Any ideas?

Hi, I installed ROS via:

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu oneiric main" > /etc/apt/sources.list.d/ros-latest.list'
wget http://packages.ros.org/ros.key -O - | sudo apt-key add -
sudo apt-get update
sudo apt-get install ros-electric-desktop-full
echo "source /opt/ros/electric/setup.bash" >> ~/.bashrc
. ~/.bashrc

Then turtlebot via

sudo apt-get install ssh ros-electric-turtlebot-robot

However when I run the turtlebot simulator via:

roslaunch turtlebot_gazebo turtlebot_empty_world.launch

I get

[turtlebot_gazebo] is not a package or launch file name

Any ideas?

Hi,

Are there any tutorials that show you how to basically copy the TurtleBot stack software for a new novel robot?

Cheers,
