2016-03-08 16:57:52 -0500 commented answer How could I install a previous version of ROS?

Thanks. I compiled the source ros-indigo-desktop. Now, I need to build robot perception packages. For example, how could I build a package vision_opencv ( https://github.com/ros-perception/vis... ) from source?

2016-03-08 14:52:01 -0500 asked a question How could I install a previous version of ROS?

I had ros 1.1.3-0trusty-20140805-0935-+0000 in my machine earlier. I had a ros package I build from source worked fine with this version. However, after I upgraded my ros to 1.1.4-0trusty-20160208-135350-0800, above package even after I build from source again won't work anymore.

So how could I downgrade my ros version to 1.1.3-0trusty-20140805-0935-+0000 (using apt-get)

Thank you

2016-02-27 00:48:24 -0500 asked a question building cv_bridge from source

In an attempt to use the OpenCV I've built from source, I've done following.

  1. Built OpenCV from source
  2. Built ros indigo desktop from source

Now I want to build packages that depends on OpenCV. What is the correct place to get the source for cv_bridge package. And what is the command I should use? is that catkin_make --pkg cv_bridge ?

I've built ros from source. The package i'm using depends on ros-indigo-libg2o as well. Where could I find the source for this? and how could I build it?

2015-12-08 23:48:52 -0500 asked a question ROS supported inexpensive($200~$300) global shutter cameras

Could someone please suggest a global shutter camera for a machine vision project. Following are the requirements.

 1. Resolution more than 640x480
 2. Field of View 120 degrees or greater (horizontally)
 3. 60 fps or more
 4. Global shutter 
 5. USB connectivity
 6. Color or Monochrome
 7. $200 ~ $300

I have seen Aptina MT9V034 / MT9M021 based cameras, but not sure whether there are drivers for ROS. Furthermore, any PointGrey camera suggestions would be helpful as well.

Thank you

2015-10-05 18:40:39 -0500 asked a question Mac OS: ROS Build Errors (Indigo)

I'm using this: https://github.com/mikepurvis/ros-ins... Trying to install Indigo. (I got the same error for Jade - after failing I uninstalled Brew, deleted directories)

OS X Yosemite, ver 10.10.5

brew --version : 0.9.5 (git revision d430d; last commit 2015-10-05)

pip --version : pip 7.1.2 from /usr/local/lib/python2.7/site-packages (python 2.7)

Any help highly appreciated.

Thanks in advance.
