This worked for me. (ros-indigo)

Thanks Jack, I'll build it from source.

Is there anyone working on velodyne package release for Ubuntu 16.04 LTS? If not i'd like to do it.

Thanks.

I am using Irobot create with kinect to work like turtlebot; I do not have gyro, so i edited driver.launch to has_gyro=false; after editing i tried turtlebot_bringup again but it did not detect roomba, Roomba was connected and turned on I doublechecked it

the log was

[INFO] [WallTime: 1310523346.309227] has gyro: False
Failed to contact device with error: ['NoneType' object has no attribute 'cal_offset']. Please check that the Create is powered on and that the connector is plugged into the Create.

What is the problem?

I was trying to rosmake eigen cause it occured as a error package while compiling turtlebot, while i was not connected to internet each time i tried errors came. but suddenely when i got connected the netbook to internet I got it worked fine and even it took only some minutes. The error was :

'''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

Do we really need to be connected while rosmaking? what is the role of internet in compiling?

I was trying to rosmake turtlebot_apps on beagleboard and got compiler warnings like

[rosmake-0] Finished <<< kdl [PASS] [ 9.12 seconds ] -- WARNING: 2 compiler warnings

Should I really care about those warnings? Are they similar as normal compiler warnings?

I installed ubuntu 11.04 natty on My Beagleboard-xM Rev. 'B'. After a lot of strugle finally i could install ROS on it. But i need to connect it to Kinect and for that i need Ogre to be installed which I can not install because of Dependency problem with nvidia-cg-toolkit, I used a lot of ways to forcefully install this dependency like using command --force-architecture with dpkg but could not do it,I would be very thankful to know they way, how should i install ogre on it. I will use the beagleboard as replacement of netbook in link text . Also i could not rosmake roscpp it took more then an hour running rosmake and then failed. Thanks in advance.

Hello I am trying to install turtlebot software on beagleboard so that i can use beagleboard rather then Laptop in turtlebot, its just a try to implement FASTSLAM1.0, I installed ubuntu and ROS on beagleboard from source, Is there any way to install Turtlebot from source. The particular error is:

W: Failed to fetch http://packages.ros.org/ros/ubuntu/di... Unable to find >>expected entry 'main/binary-armel/Packages' in Release file (Wrong sources.list entry or >>malformed file)

E: Some index files failed to download. They have been ignored, or old ones used instead.

Is it good practise to use beagleboard on turtlebot instead of a high power and high processing laptop for implementing FASTSLAM1.0?

Can Kinect run on Beagleboard using ROS?

I have tried running ROS on Beagleboard. I want to know which ARM based Hardware is preferable or Recommended to run ROS.

Hello! I tried installing rgbdslam, but got this error:

I have Ubuntu 11.04 and ros-electric version on my laptop. I was successful in doing same on workstation with same Ubuntu and ros versions. The only difference here in laptop is that I dont have root, and someone had already worked on this lappy with rgbdslam and g20 etc. I am new to ROS, will appreciate any help! Thanks in advance!
