Build Status

This package performs coverage with a swarm of unmanned aerial vehicles (UAVs). The UAVs optimally divide the area to be covered among each other. It is part of the swarm behaviors library.

Dependencies

This package depends on the following message definitions: * cpswarm_msgs

The following library packages of the swarm behaviors library are required: * swarm_behaviors_position

The following packages of the swarm functions library are required: * area_division * coverage_path * target_monitor (only if single_target=true)

Further required packages are: * roscpp * actionlib

Execution

Run the launch file

roslaunch uav_optimal_coverage uav_optimal_coverage.launch

to launch the uav_optimal_coverage node.

The launch file can be configured with following parameters: * id (integer, default: 1) The identifier (ID) of the CPS used for name spacing in simulation. * output (string, default: screen) Whether to show the program output (screen) or to write it to a log file (log).

In the param subdirectory there is the parameter file uav_optimal_coverage.yaml that allows to configure the behavior of the uav_optimal_coverage node.

Nodes

uav_optimal_coverage

The uav_optimal_coverage performs coverage with a swarm of UAVs. The coverage is optimal in a sense that the area to be covered is divided among the UAVs to avoid overlapping regions to be covered multiple times. Within each region, the assigned UAV sweeps the area using simple back and forth (boustrophedon) motion. Once the region has been sweeped completely, it aborts the coverage. When the parameter single_target is set to true, it succeeds once a target has been found and returns the target ID and position. The area division and coverage path generation are provided by the swarm functions library.

Action Goal

  • uav_coverage/goal (cpswarm_msgs/CoverageGoal) A goal that starts the optimal coverage behavior. It contains the altitude at which to operate.

Action Result

Subscribed Topics

  • target_found (cpswarm_msgs/TargetPositionEvent) Position and ID of a target detected by the target monitor. Only subscribed when single_target is set to true.

Services Called

Parameters

  • ~loop_rate (real, default: 5.0) The frequency in Hz at which to run the control loops.
  • ~queue_size (integer, default: 1) The size of the message queue used for publishing and subscribing to topics.
  • ~single_target (boolean, default: true) Whether the algorithm will succeed / terminate once a target has been found.
