The motion_planners stack includes 3 different motion planners developed at Willow Garage or developed by our collaborators. This set of planners has been used extensively on the PR2 robot for motion planning for the PR2 arms. We (along with our collaborators) are actively involved in improving these planners and intend to further develop and release new features in the future.
The 3 motion planners currently in the stack are:
OMPL - This set of motion planners was developed by Lydia Kavraki's group at Rice University in collaboration with Willow Garage. It implements several probabilistic motion planners. It is also a great building block for any users wanting to implement new motion planning techniques since they can build on the components already present in this library.
SBPL - This motion planning library has been developed by Maxim Likhachev's group (at CMU and the University of Pennsylvania). It implements search-based planners, in particular anytime search based planners, for general robotic systems.
CHOMP - CHOMP is a motion planner based on trajectory optimization. It generates smooth, collision-free trajectories. It was originally implemented by Mrinal Kalakrishnan from USC while he was a summer-intern here. It has since been modified extensively for use with the Willow Garage manipulation pipeline.
To see examples of how to use the motion planners, check out the arm navigation tutorials.
The ROS and C++ APIs for the planners themselves are mostly unreviewed and unstable. However, the interface to the motion planners using the GetMotionPlan message (or other messages from the motion_planning_msgs has been through review. While the interface is still classified as UNSTABLE, we will make every attempt to not change the interface substantially.
