Name Version
move_basic 0.3.2



This package contains a node that performs very basic navigation. The path planning consists of rotating in place to face the goal and then driving straight toward it. It is designed to provide the same interfaces as move_base. If lidar or sonar sensors are present, it will attemp to stop to avoid a collision with obstacles.

Installing software

First you must install ROS (Robot Operating System), see install ROS for more details.

The package can be installed:

 $ sudo apt-get install ros-kinetic-move-basic

To run

To run, give the following command:

 $ rosrun move_basic move_basic

Node details

Please refer to the move_basic wiki page for node documentation.
