Dependencies

This package depends on the following message definitions:

• geometry_msgs

• cpswarm_msgs

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

• swarm_behaviors_position

The following packages of the sensing and actuation library are required:

• *_vel_provider
• *_vel_controller

Libraries

velocity

The velocity library provides velocity related functionalities. These include retrieval of current velocity, computation of relative velocity, computation of velocity to reach a certain waypoint, and setting the actuators velocity.

Subscribed Topics

vel_provider/velocity (geometry_msgs/TwistStamped)

• Current velocity of the CPS.

Published Topics

vel_controller/target_velocity (geometry_msgs/Twist)

• The target velocity at which the CPS shall move.

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.
