Pose-Graph SLAM in ROS: We have shared two implementations of pose-graph SLAM in ROS using open_karto as a front-end and popular back-end solvers like G2O and GTSAM. You can use these packages to do real-time map building using laser scan data and odometry generated by a simulated robot in Gazebo or a physical robot.

  • slam_karto_g2o [code]: pose-graph SLAM using g2o as backend.
  • slam_karto_gtsam [code]: for pose-graph SLAM using GTSAM as backend.

Belief Space Planning with OMPL [code] : We have built an implementation of Feedback Information Road Maps (FIRM) and Node-based MultiModal Motion Planning (NBM3P) with OMPL. FIRM is a multi-query approach for planning under uncertainty which is a belief-space variant of probabilistic roadmap. M3P is a planner to localize lost robots (robots with a multi-modal belief). Our goal is to make our planners open source so as to enable the motion planning community to use methods like FIRM, NBM3P for exciting new applications. Our long term vision is to upstream these features to the OMPL library.

FIRM MATLAB Toolbox [code] : This application is an implementation of Feedback Information Road Maps (FIRM) in MATLAB. There are easy to use demos with a GUI.
