Revision history [back]

The issue is that you haven't installed something that are required to build baxter related packages from source (em in your case). My guess is that you need to run something like the following (at the top of your catkin workspace) in order to redress the dependencies.

rosdep install --from-paths src --ignore-src --rosdistro groovy -y -r

If this resolves the issue, I don't know why it's not included in the tutorial you referred to.

Btw for the questions regarding Baxter Research Robot you might get more eyes on its email forum.
