  • Gazebo Blank Message block


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).

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.


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