I worked on the raspberry pi setting up ROS indigo on Raspberry Wheezy.
I followed the following tutorial on ROS.org, but most of the code did not work since Raspberry Wheezy is an old version, that conflicts with a lot of the packages. The most common error was that the Debianhelper was not a high enough version for most of the package dependencies. The solution for the problem was to manually install the newest versions for each package though github.
I was able to most of the tutorial, but encountered a bug a the end of the tutorial. I was not able to build the catkin workspace this week to start testing the robot.
