ROS Motion Planning

Robot Motion planning is a computational problem that involves finding a sequence of valid configurations to move the robot from the source to the destination. Generally, it includes Path Searching and Trajectory Optimization.

• Path Searching: Based on path constraints, such as obstacles, to find the optimal sequence for the robot to travel from the source to the destination without any collisions.

• Trajectory Planning: Based on kinematics, dynamics and obstacles, it optimizes the trajectory of the motion state from the source to the destination according to the path.

This repository provides the implementation of common Motion Planning algorithms. The theory analysis can be found at motion-planning. Furthermore, we provide Python and MATLAB version.

Your stars, forks and PRs are welcome!

0. Quick Start within 3 Minutes

Tested on ubuntu 20.04 LTS with ROS Noetic.

1. Install ROS (Desktop-Full suggested).

2. Install git.

   sudo apt install git

3. Other dependence.

   sudo apt install python-is-python3 \
   ros-noetic-amcl \
   ros-noetic-base-local-planner \
   ros-noetic-map-server \
   ros-noetic-move-base \
   ros-noetic-navfn

4. Clone the reposity.

   git clone https://github.com/ai-winter/ros_motion_planning.git

5. Compile the code.

   cd ros_motion_planning/
   catkin_make
   # or catkin build
   # you may need to install it by: sudo apt install python-catkin-tools

6. Execute the code.

   cd scripts/
   ./main.sh

   NOTE: Modifying certain launch files does not have any effect, as they are regenerated based on the src/user_config/user_config.yaml by a Python script when you execute main.sh. Therefore, you should modify configurations in user_config.yaml instead of launch files.

7. Use 2D Nav Goal in RViz to select the goal.

8. Moving!

9. You can use the other script to shutdown them rapidly.

   ./killpro.sh

10. For more details on system configuration, please refer to Configuration.
