Hello,

I am very sorry if my question has an obvious answer but:

I am new to Raspberry Pi and TurtleBot and ROS. I know I can get ROS on the Raspberry Pi, I found a tutorial for that. But before I go through the steps to get it all set up, can I use a Raspberry Pi as the TurtleBot Netbook? Is there anything extra I will need? Is there an example somewhere?

Also, I'm a fan of Groovy, will TurtleBot even work with ROS Groovy right now because the installation instructions are blank?

Any help would be greatly appreciated!

-Kelly

I was hoping someone already did this! I am working with some folks who think the best approach for ROS on an RPi is to use ARCH - supposedly it is faster. I don't know if it will run as a ROS master host.

I feel sure that TurtleBot will work on Groovy, once all the problems have been solved. :-)

DrBot- would you be willing to try to work together on this? I am going to start on the process tomorrow, either way I will post the results here. I am hoping to process the kinect data, or at least send it to the work station.

Goal is the RPi will launch the robot and kinnect, but RVIZ will be run on a wifi connected laptop or other mobile device. I tried to build he openni drivers on Rpi Arch, but the buld failed on the 'clean'.

BTW were able to capture data from both a XV-11 neato node, and a Kinnect using the turtlebot kinnect launch on an ubuntu laptop using fuerte. This is all work associated with the Ubiquity robotics project.

Hi I'm able to launch turtlebot using raspberry pi wheezy with groovy, and teleop using workstation, but kinect is over burden on processor, were you able to process kinect data?

Hi i dont know what im doing wrong, I've installed ros groovy on the raspberry pi and trying to move the kobuki motors with the kobuki node and the keyop but the turtlebot doesn't move. I hope anybody can help me

Are you trying to just control the motors, or are you trying to do the Kinect image processing? I think the Pi is powerful enough for the former but not for the latter.

The Rpi will capture the data and Rviz will be run on a remote computer.

I am working on getting the kinect to work with my raspberry pi but I have not seen anyone getting a pointcloud from a kinect. So no, right now it is not possible to replace the netbook with a raspberry pi and I doubt that it is possible at all.

We are able to run a roscore on Raspian with groovy and use it to control an Arduino.

The build takes forever on a Pi. Once we get a working build, we burn SD cards.

check out this link, it also provides a sd image with the mobile and perception preinstalled

If you use 7805 power regulators to feed your rpi, make sure you use heatsinks on them. That took a while to debug.... Also, just use one of the rpi images rather than compiling yourself and save yourself a week of frustration.
