Gazebo Blank Message

Create blank Gazebo command

  • Library:
  • Robotics System Toolbox / Gazebo Co-Simulation

  • Gazebo Blank Message block

Description

The Gazebo Blank Message block creates a blank Gazebo message or a command based on the specified type. The block output is a bus signal that contains the required elements for the type of command. Use a Bus Assignment block to modify specific fields in the bus signal. The bus signal initializes with zero value (ground).

To create blank Gazebo command, connect to a Gazebo simulation. Open the block mask and click Configure Gazebo network and simulation settings. For more information see Configure Gazebo Simulation.

This block is part of a co-simulation interface between MATLAB® and Gazebo for exchanging data and sending commands. To see a basic example, check Perform Co-Simulation between Simulink and Gazebo.

Limitations

  • Models that use this block do not support Code Generation or Rapid Accelerator mode.
