2012-07-19 09:31:08 -0500 commented question Bad Gyro Callibration

I seem to have found the right combination of calibration numbers to make the gyro report correct values. I still get an error message on the dashboard saying bad gyro calibration, but the robot model in rviz is turning almost exactly as much as the physical turtlebot.

Did you ever get this issue resolved? I have basically the same problem. I also noticed the raw gyro value would change if the robot was turning, which seems to indicate the gyro is NOT malfunctioning.

Have you explored the tf tree rgbdslam generates for you? It seems slam_transform is the localized position of the kinect.

This question is a duplicate of which you asked a month ago.

This looks like a bug in rviz and/or a lack of support for your graphics hardware. You should probably file a bug against rviz. Use this wiki section for info on how to make a usable bug report: how to make a usable bug report.

OK, Thanks, I posted it under different tags because I realized it was an rviz issue and not a kinect issue and thought it needed different background. I'll take my other post down.

2011-09-12 06:34:43 -0500 asked a question rviz sensor data does not rotate

Hello, I've been using ROS for quite a while now, and I recently upgraded from cturtle to electric (skipped diamondback). I started with a fresh install of 11.04 64 bit on an i7 iMac 2010 model. I followed the instructions for a generic install, using apt-get with ros.

rviz does not let me rotate any of the sensor data I have access too in it's window, it shows the data, but rotating the display does not rotate the data itself. My transforms are setup correctly (the most basic of transforms from base_link to laser, 0,0,0,0,0,0). I'm viewing just a laser scan data type. Another odd behavior I viewed was the first time I started rviz on two different installs of ros it had no grid by default (which was not the case on cturtle) and when I tried to add a grid, there were no data types listed as available. Once I restarted rviz the data types showed up in the data types list. Possibly related.

The same happens for Kinect data, I can view the point cloud in the rviz window, but I cannot change the orientation of the point cloud.

I tried reinstalling ros, installing diamondback, installing via svn.

If I had more karma I would upload some screen captures.

I have no idea what the problem is and I would appreciate any help I could get. Please let me know if I need to include more information.

2011-08-31 07:57:15 -0500 asked a question openni_kinect rviz display error, pointcloud2 is displayed but cannot rotate or change view

I just installed a vanilla diamondback install (desktop-full) through apt-get and then installed openni_kinect the same way as per the instructions here

I can start the node just fine with

$ roslaunch openni_camera openni_node.launch

I can then view the raw RBG image in rviz and I can see the pointcloud2 data in the display, but I cannot rotate the display around to view the data from another angle. i.e. Right click+dragging mouse does rotate the grid I added, but does not rotate the point cloud data.

The transforms appear to be ok and my fixed frame is /openni_camera and my target frame is the same.

I'm running a fresh install of Ubuntu Natty, 64 bit on kernel 2.6.38-8-generic on an i7 iMac
