Rud,
    Was your friend trying to use a webcam via USB or was he using the Rpi camera module? The camera module via the camera port is much faster.

Regards,
Doug P.

The Corobot project is interesting especially since they are using a R-Pi B 2. I would wonder how much vision processing you can accomplish with a Pi, even the B 2. A friend did some work with a Pi B and OpenCV for sample detection. The frame rate was around 2-3 frames per second.

  I have used a IFC6410,BBB,UDOO with ros. Though I have not used any of them with a kinect or xtion. My current plan is to use the neato lidar instead with those. I plan on trying the new raspberry on this robot if it makes funding,  https://www.indiegogo.com/projects/designed-for-education-geared-for-makers/x/1661938 

  If not it will go on one of my other platforms i have laying around.

    David,
          Maybe Paul or Jason will bring Turtlebot to the March meeting.

          If you look at DPRG video  http://youtu.be/qkshrmF_j_E , between 1:29 and 1.50 you can see Jason’s ROS controlled Turtlebot running the table on a Six Can demo at Roborama2014a. Sure this demo could be done in other ways (i.e., see our last competition in December), however this is an example of a ROS based robot solving the problem. If I remember right, Jason was using localization and mapping based on a ROS implementation of SLAM to collect the cans. 

         I would love to see a Turtlebot or another ROS based robot in the CanCan Soccer at Roborama2015a. We might have to adjust the weight limit. I believe Jason’s robot was pretty heavy since it was carrying a laptop.

         Paul, I have a question. Is the new Rpi 2 or the BBB rev B powerful enough to replace the laptop typically used by ROS?

    Regards,
    Doug P.

    Not to sound overly cynical, but might this talk perhaps include a demo of an actual robot running ROS?   Maybe doing something that can't be done with a PIC chip?   Or will this be just another demo of a couple of laptops streaming data to each other?  

    Too much to hope for?  Paul, the ball's in your court!

    cheers

      -All,
          Paul Bouchier has agreed to provide a tutorial on ROS at the DPRG March 14th meeting. Here is what I asked him to cover, if you want something different speak out.

        “Paul, I think we are looking for a what are the requirements, how to install, how to setup, what are the parts of ROS, how to use on the most basic level, type of talk. “

      Regards,
      Doug P.
