Reinstall ROS

[KM6VV]

I think I've gotten too much confused between Fuente and Electric. How
do I uninstall ROS (both) and start again?

Thanks!

You should be able to do a "sudo apt-get remove ros-fuerte-common ros-electric-common; sudo apt-get autoremove" to remove the metapackages, then automatically remove all that depends on the metapackages for the common ROS package.

If you compiled from source, a simple rm -rf /opt/ros/* will remove all of ROS. (You may also have to remove /etc/ros/* as well).

Hey Alan,

After following Michael's procedure, if you decide to install or leave
Electric as your ROS version, I have a little ROS book coming out that
might be of some use to you. I have to ask Wayne if it is OK to post
the link on the forum (since it is a commercial product) but at the
moment the code that accompanies the book is written for ROS Electric
and I will have to write a new revision to handle some of the changes in
Fuerte which could take some time.

Patrick:

Consider me asked and your book approved. Go for it.

Thanks Wayne! I'll put out an announcement later today.

Yes!

I think that is what I'm going to do. And I'd be interested in your book as well.

Thanks!

Hello HBRC'ers,

I have written a little book called ROS By Example.  The book is aimed at new ROS users who want to go beyond the Beginner Tutorials and create some working ROS applications, either in simulation or on a real robot like the TurtleBot.  The book provides step-by-step explanations of a number of ROS programming examples using code that can be downloaded from an accompanying Google Code repository.  You can see a preview of the book including the table of contents at the web page above.

There are some important caveats if you are considering getting the book:

* The companion code is written for ROS Electric, not Fuerte.  There are a number of changes in Fuerte that are going to require me to make a separate version of the code for Fuerte.

* I have tested the code under Ubuntu 10.04 and 11.10 but not 12.04 since Debian packages are not available for ROS Electric under 12.04.

* The book assumes the reader has done at least the Beginner Tutorials on the ROS Wiki.  It also assumes at least a one-time reading of the TF tutorials.  In fact, there are a lot of links in the book that point back to the Wiki but this is all in the spirit of not reinventing the wheel.

* The code samples are written in Python, not C++ so if you don't like Python, this book probably isn't for you!

* A print version of the book will be coming soon but I think the PDF version will probably be more useful to most folks.

Patrick,

The book looks promising, but they don't appear to be ready to sell downloads?

How do I get a copy, I could use it now!

Alan,

I just downloaded it.  Took a few minutes for them to do whatever it is they do to get the PDF to your download page, no more then 5 probably.  It's Volume 1, do I smell Volume 2 in the wind?  And how to get the author to autograph a PDF?  :)

Time for bed, I have to sweat and glow in the dark in the morning.

Hi Alan,

I hope your download eventually showed up.  It's disappointing to here that there is a delay.  I did a test purchase before going live but the receipt ended up in my spam folder for about 15 minutes before I realized it so I couldn't tell what the delay was on the actual download page.

If others experience more than a few minutes delay, please let me know directly (pat...@pirobot.org) and I'll report it to Lulu.

You must have a better nose than an airport sniffer dog because a Volume 2 is about as far away as the Moon. :)  (V1 took me about a year...)  But yeah, the thought has crossed my mind, especially to cover multi-jointed arms and grasping.  With any luck, someone else can write a V2 before I do. :)

Hi Patrick,

I got it.  Probably got hung up because of the new subscription to Lulu, and my unfamiliarity with the Lulu website.

Nice to see a readable PDF.

This is the first book about ROS known to mankind. Am I correct?

[Charlie Chiau]

Where is this ROS pdf that we're talking about?

[KM6VV]

Sounds like it!

About time someone wrote a book on ROS.  Who better then one of our members!

I bought and downloaded it; nice to see a real PDF, as I don't have an E-book reader.

Hi Charlie,

The link is in the first post of this thread but here it is again:

Note that the system requirements are ROS Electric and Ubuntu 10.04,
10.10 or 11.10.

I'm really happy to see a book like this. I bought it but was annoyed that I have to sign up for YetAnotherUserAccount and set YetAnotherPassword.
