teb_local_planner

teb_local_planner ROS Package

The teb_local_planner package implements a plugin to the base_local_planner of the 2D navigation stack. The underlying method called Timed Elastic Band locally optimizes the robot's trajectory with respect to trajectory execution time, separation from obstacles and compliance with kinodynamic constraints at runtime.

Videos

The left of the following videos presents features of the package and shows examples from simulation and real robot situations. Some spoken explanations are included in the audio track of the video. The right one demonstrates features introduced in version 0.2 (supporting car-like robots and costmap conversion). Please watch the left one first.
