Hacker Dojo. The meeting will start at 7:00 pm. SIG is an informal
meeting where we just meet and mingle to show off and talk robots. You
don't need to be a member of either HBRC or Hacker Dojo to attend.
Hacker Dojo is at 599 Fairchild Dr, Mountain View, CA 94043. Upon

Does anyone have any suggestions on improving GPS accuracy/fix?
I have already enabled WAAS, but that does not seem to do much. At 9 sattelites I get about 10-15 feet
accuracy (most of the time).
Also, for some reason, when I tested the GPS at the Menlo Park Tech Shop, I got 11 satellites inside of the building! While at my house in Sunnyvale I can't even get a 10 sattelite fix outside. I wonder how its going to be in San Mateo at Robogames...

2. Check to see which Arduino chip you are using. Though the ATmega328 and 168 look identical, the programmer will balk at you if you get mixed up. A jewelers loupe or small electron microscope are useful for reading the number of the chip.
I've got Mike's neato_node running on my laptop in groovy, but haven't got rviz to show me a cloud yet. My next step is to see if I can get the neato_node to work on the RPi. Does anyone know if a ros_workspace and a catkin_ws can coexist peacefully? It seems I can run one or the other but not both at the same time on my Unbuntu 11.10 and AMD-64 laptop.
Ubuntu 10.04 and Diamondback.
Following the ROS tutorials, I created a package:
roscreate-pkg my_py std_msgs rospy roscpp
I added a launch folder with a py.launch file and a nodes folder with a

it seems urethane is the best material for belts. However, I have been
unsuccessful finding urethane o-rings around an inch I.D. What would be
really great is a kit, so I could get the perfect size and not have to make
a approximation when I order. Can anyone give me advice on where to get
product that may give people ideas. He makes cubes that can be used to
create musical compositions.
I tired to follow the tutorial, without much success
After I get the wstool, wstool init barfs at me.
BTW - making some progress at Ubiquity Robotics:
roslaunch neato_node bringup.launch
rosrun neato_node neato.py _port:=/dev/ttyUSB0
Traceback (most recent call last):

The February meeting video has been uploaded starring David Crawley and
the Ubiquity Robotics Team. (Also includes Show & Tell and
Announcements as usual.)
I have it working in feurte OK. But in groovy it is giving me a missing driver declaration. I've traced it to the
neato_node/node/neato.py file - here line 44 says neato_driver.neato_driver. And ROS tells me this file cannot be found.

Following instructions from Patrick's Wiki, got rosmake to compile in a workspace, there was one unresolved dependency.
This was using the new Raspian image from Kurt, slightly edited to add workspaces, ssh enabled and various environment variables tweaked to reflect package locations, IP address etc,
