Hi ROS users, I was wondering whether there was some interest in the community to develop a common interface for Ackermann steering based robots. We have an autonomous car using ROS (utexas-art-ros-pkg) for which we use a proprietary message format to control the driver. We are now trying to port over the code-base for a number of smaller robots based on the traxxas platform to ROS. We were hoping to discuss the driver interface along with an interface for some basic GPS based navigation for the traxxas robots. In case there are existing examples for this this type of work already, I would appreciate it if someone could point them to me. Thanks, Piyush
