I can't get the turtlebot to calibrate using the turtlebot_calibration calibrate.launch file. It just outputs "Still waiting for scan" and I can see that the IR sensor never turns on. The kinect works fine when I've tried gmapping though so I know it does work.

I upgraded my turtlebot to ROS Hydro. I can run all typical test programs for the turtlebot without any problems but when I try and create my own packages it can't find turtlebot_node. I know this method worked with Fuerte.

For example: This is how I created a new package called color tracking: catkin_create color_tracking rospy std_msgs turtlebot_node

And then catkin_make gives an error that it can't find turtlebot_node.

I upgraded my turtlebot from Fuerte to Hydro. I went through the whole install and everything worked.

But roslaunch doesn't work now. I can still use roscd to move to all of the packages I just can't launch them. I get the following error when trying to launch the turtlebot:

[minimal.launch] is neither a launch file in package [turtlebot_bringup] nor is [turtlebot_bringup] a launch file name

I'm trying to do color blob tracking with my turtlebot. I'm using cmvision and used color gui to the the correct YUV numbers for the color I want to track. I add those the the colors.txt file and everything seems to be going well. When I run cmvision the colors seems to be inverted and so the blob tracking doesn't work. I don't get why it's doing this. I'm using the default launch file and only changed it to use the kinect camera.

I'm trying to install Gazebo but running into the following errors. I think it has something to do with trying to update Ubuntu. This is with 12.04 and Fuerte.
