Improving GPS

Wed, 03/27/2013 - 06:11
Hello all,
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...

Some important hints to reduce frustration.

Wed, 03/27/2013 - 02:36
1. Be sure to disconnect all cables for your microcontrollers before throwing them into a shopping bag. Trying to re-solder a torn off micro USB surface mounted socket is difficult and might be impossible if you can't even find the torn off socket.

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.

Ubiquity Robotics Progress Report.

Tue, 03/26/2013 - 07:46
We are making progress with the project. I've been working on the navigation team. Patrick's ros_arduino_bridge can work on an RPi, and further more can be controlled from a remote wireless device.


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.

make and run a simple Python file?

Mon, 03/25/2013 - 21:37
I'm trying to get a simple Python program running under ROS (& Turtlebot).

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 file.

I ran rosmake

o-ring belts

Mon, 03/25/2013 - 21:37
I am trying to find o-ring belts for my Nanosumo robot. Researching online,
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

Interesting Product

Mon, 03/25/2013 - 21:37
I met this guy in the Internet of Things meetup. He has an interesting
product that may give people ideas. He makes cubes that can be used to
create musical compositions.

Has anyone done this and is there a good explanation of what the process is?

I tired to follow the tutorial, without much success

After I get the wstool, wstool init barfs at me.

ROS neato node not running in groovy?

Tue, 03/19/2013 - 21:29
Has anyone got the ROS Neato node working in Groovy?

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/ file - here line 44 says neato_driver.neato_driver. And ROS tells me this file cannot be found.


Tue, 03/19/2013 - 07:08
I am trying to get a Nanosumo robot ready in time for Robogames. Is anyone
else competing in Robogames?

Raspberry Pi Event

Fri, 03/15/2013 - 23:37
I saw this and thought maybe some of you might be interterested.

MAKE has partnered with Engadget as a media sponsor for their premiere
event EXPAND on March 16-17, at Fort Mason in San Francisco.The event
provides a unique opportunity to hear from your favorite consumer
electronics luminaries, Engadget editors and MAKE editor-in-chief Mark

ROS_ARDUINO_BRIDGE, Raspberry Pi, Groovy, so happy together.

Fri, 03/15/2013 - 23:37

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,
