Hi,

If you got ROS from package manager, try

sudo apt-get update
sudo apt-get dist-upgrade

2011-06-27 16:00:10 -0500 asked a question How do I update ROS?

I just received my Kinect. I am in the process of installing ubuntu 11.04. I had a prior version of ROS installed... Is there a simple way to upgrade the current installation?

Sorry, this is a very newbie question. I've spent a little time searching for the answer but it hasn't jumped out at me.

I see that none of the Turtlebot kits (currently) list an IMU. Is that accurate or have I missed it in the listings?

I've been anxiously waiting for TurtleBot since it's announcement... I'm disappointed, though, in the pricing. Parts seem a little expensive: $99.95 for the standoff kit!?!?! This is not a PR2!

There is sooo much good coming out of Willowgarage. ROS is amazing. The interest in sharing so much information is astounding to me. All of that has been truly a turning point. But Sheez... if Turtlebot is supposed to be an affordable way to gain entry into the field, how does one justify $99.95 for a handful of parts I should be able to duplicate by visiting my local hardware store?

Hi Mike,

One method that works for me is to turn off user authentication in the Rovio web interface: click Settings->Security then uncheck the box next to Enable User Authentication and click the Update button. With this done, you can put anything you want in the username and password fields in the rovio.launch file (like "foo" and "bar").

Another method is to add a Rovio user as a Guest (again via Settings->Security) and use a simple username and password; e.g. "foo" and "foobar" (password must be at least 6 characters) then use these in the rovio.launch file.

Thanks for the reply. I wanted to avoid having to enter anything. I understand how to put in the information in the rovio, but wanted to keep it empty and learn how to enter null into the launch file.
2011-02-18 12:10:53 -0500 asked a question launch rovio

I had a few more minutes to test things. My rovio currently has no username or password. I'd like to keep it that way. I tried editing the launch file so that the values were "" but that seemed to generate an error.

Should I have them equal to nothing, to "", to blank space, to " " or what?

That means everything is already installed.

Those messages are confusing. I opened rosdep enhancement ticket #3346 to make the output clearer.

2011-02-17 14:08:40 -0500 asked a question Rosdep Error

I'm a newbie to Linux and ROS.

Have successfully installed Ubuntu and (I believe) ROS and am in the process of installing various stacks.

One stack is the iheart-robotics rovio driver.

I've attempted to follow the directions to the point I am supposed to issue "rosdep install rovio" from within the installation directory.

It spins for a few seconds and reports an error. The sequence is:

mike@mike-EP45C-UD3R:~/mikeros/iheart-ros-pkg$ dir
ihr_demos  ihr_tools  README  rovio
mike@mike-EP45C-UD3R:~/mikeros/iheart-ros-pkg$ cd rovio
mike@mike-EP45C-UD3R:~/mikeros/iheart-ros-pkg/rovio$ rosdep install rovio
executing this script:
 set -o errexit
#No Packages to install
mike@mike-EP45C-UD3R:~/mikeros/iheart-ros-pkg/rovio$

I presume this is an error. Or does this indicate that the dependencies have previously been resolved?

Many thanks...

-Mike
