Planning and control for car-like vehicles

Overview

Pure pursuit controller and Reeds-Shepp sampling based planner for navigation in SE(2) space. This package has been mainly intended for car-like vehicles, although it can be used with mobile bases too.

How is this package different from other SE(2) planning/control packages?

• Provides planning and control for car like vehicles which are non-holonomic
• Correctly handles both forward and reverse driving
• Allows joint path and approach pose planning when we only know approximate target location
• Comes with a minimal set of dependencies
• Core algorithmics is separated from ros dependent code
• Tested on real-hardware
• Comes with a car example
• Integrated with grid_map package
• Features visualizatios and rviz planning interface
• Easily extensible
• Supports dynamic reconfigure for controller tuning

Warning: At the moment, this planning and control framework uses geometric planners which makes it unsuitable for high-speed driving. It is meant to be used for slow maneuvers, e.g. parking maneuvers.
