freefloating_gazebo

A Gazebo plugin to simulate underwater vehicles and visualize with UWsim.

Gazebo plugins

The package builds two Gazebo plugins:

• freefloating_gazebo_fluid (world plugin) simulates buoyancy and viscous force from water

• freefloating_gazebo_control (model plugin) opens topics for wrench and joint states, in order to control the considered robots

Built-in PID control

An external PID controler is available: pid_control.

These PID's allow position, velocity or effort control of the vehicle body and joints.

Subscribes to setpoint and states topics, and publishes on the wrench and torque topics that are subscribed to by the freefloating_gazebo_control plugin. Private parameters body_control and joint_control allow setting the default mode (body: position / velocity / effort (body wrench), joint: position / velocity / effort).

This PID advertises the corresponding services to switch some of the axis (joint names or x, y, z, roll, pitch, yaw) to another type of control.

Examples

The examples can be downloaded from the freefloating_gazebo_demo package.
