When running the navigation with dwa_local_planner, and give the first goal as an in place rotation, the robot won't move (except for recovery behaviors), and gives the below output. GitHub Instantly share code, notes, and snippets. and at the same time the lowest distance from the final goal. cfg. If so, why are you cloning the robot_navigation package directly into your workspace instead of installing it via $ sudo apt-get install ros-kinetic-navigation? So I decided to try it out. A tag already exists with the provided branch name. These parameters are grouped into several categories: robot configuration, goal tolerance, trajectory configuration, obstacles, optimization, planning in distinctive topologies and miscellaneous parameters. Tests were based on continuous movements between three waypoints placed in a confined space, in both static and dynamic environments. 2 years ago. (https://ieeexplore.ieee.org/abstract/document/580977). But, if you give a translation goal first, it moves normally, and from then on, it can rotate in place without a problem.
