Jack,
Nate,
This looks like a cool device, definitely interesting for robotics
work. Thanks for making a ROS package.
Note that REP 103 also specifies angles in radians:

As noted, there can be exceptions, domains where the default
conventions are not appropriate. We should not be pedantic about it. A
recent example came up with the GPS message discussion. Latitude and
longitude should be expressed in degrees, not in radians.
I made some similar mistakes in a couple of our autonomous vehicle
messages [[http://www.ros.org/wiki/art_msgs]]. I now wish I'd gotten
them right to begin with. The standards were not so clearly spelled
out back then. In my experience, it is a lot of extra work to change
messages later (more due to bag migration than to fixing all the
references).
