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.
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, give the following command:
$ rosrun move_basic move_basic
Please refer to the move_basic wiki page for node documentation.
New obstacle avoidance behavoir (March 2019)
New behavior was added in the
side_dist branch. The behavior is to
follow a wall or similar object at the side.
/follow_mode: (int) Follow mode: 0 None, 1 Left, 2 Right.
~min_side_dist: (float) Target distance to maintain in side following mode
meters. Default 0.2.
~max_side_dist: (float) Maximum distance in meters at side before determining there is nothing there. Default 1.0.
max_follow_dist_without_wall: (float) Maximum distance to travel with no side object in following mode before aborting. Default 0.5.
~max_lateral_deviation: (float) Maximum deviation from a straight path
before aborting the current goal. Default 4.0.
~side_turn_weight: (float) Weighting of side turn control to avoid obstacles. Default 3.0.
~side_recover_weight: (float) Weighting of side turn control to keep on plan. Default 3.0.
~lateral_kp: (float) Lateral control P term. Default 0.1.
~lateral_ki: (float) Lateral control I term. Default 0.
~lateral_kd: (float) Lateral control D term. Default 50.
