Gazebo Planar Movement Plugin

Distro CI Status
Humble CI

Motivation

Movement planning packages in ROS for differential drive or omni-directional drive mobile robots usually publish a Twist message on the topic cmd_vel. In order to simulate these robots, a Gazebo plugin is required to listen to this topic, then apply the appropriate movement to the simulated robot Model in Gazebo.

Goals

  • If in position mode:
    • Listen to the /cmd_vel Twist message and update the appropriate Gazebo Model with a time interpolated position update based on the Twist linear and angular velocity.
  • If in velocity mode:
    • Listen to the /cmd_vel Twist message and update the appropriate Gazebo Model velocities with the Twist linear and angular velocities.
  • Odometry in the form of nav_msgs/Odometry shall be published on /odom or odometry_topic parmeter. This is usually used by external ROS localisation or navigation packages.
    • If ground_truth is False, configurable noise shall be applied to the odometry value.
  • Imu tracking shall be published in the form of sensor_msgs/Imu.

Requirements

  • Physics must be disabled using gazebo_no_physics_plugin if in position mode.

Definitions

Definition Description
Model An instanced SDF in Gazebo. Models consist of Links connected by Joints.

Design

Assumptions

Limitations

  • The plugin simulates planar movements only. Any Z axis components of velocity shall be ignored.
    • The model position Z component shall always be set to 0.0.
  • Position uncertainty is not reflected in the covariance components of the Odom and Imu topics published.
    • All relevant xyz rx ry rz covariance components are set to 0.0001.
