MPC Waypoint Tracking Controller (Local Planner for ROS Navigation)

Abstract

To move the robot on the predefined path accurately based on the plan shall be published by Global planner. Non linear model predictive controller shall help to calculate the cmd_vel based on the desired trajectory. This local planner shall be used along with WaypointsGlobalPlanner.

Dependencies

- CppAD (included in this build)
- Ipopt (included in this build)
- Eigen (sudo apt install libeigen3-dev)

How to compile (Assumed that the catkin workspace setup already)

- cd catkin_ws/src
- git clone https://github.com/balamuruganky/mpc_waypoint_tracking_controller
- cd ..
- catkin_make

Configuration

Please refer MoveBase Parameters

Caveats

- Robot Position and orientation must be towards initial waypoint position and orientation.
- Waypoints must be dense enough to calculate the cmd_vel.

Demo

Please clone bbblue_bot to run demo of mpc_waypoint_tracking_controller along with waypoints_global_planner

TODO

- Example Rviz simulation launch file
- Test the controller with different desired trajectories
