motionplanning

Motion planning algorithm implementation in Python and C++

Table of Contents

C++ useage

C++11 standard, use Rviz to show algorithm, so you should install ROS.

  1. put this package in your ros workspace, e.g. ~/catkin_ws/src/
  2. cd ~/catkin_ws and catkin_make
  3. source devel/setup.bash
  4. launch script, e.g. roslaunch cpp_rviz a_star.launch

Dubins path algorithm

Dubins algorithm have 6 types path as below.

shortest dubins path with different end point

6 types of dubins path with same end point

RRT-Dubins

rrt_dubins

RRT*-Dubins

Reeds Shepp path algorithm

The difference of Reeds Shepp path and Dubins path is that Reeds Sheep path have both forwards and backwards. So Dubins path is a subset of Reeds Shepp path.

shortest Reeds Shepp path with different end point

different types of Reeds Shepp path with same end point

Hybrid A* algorithm

based A* algorithm and Reeds Shepp path algorithm
