Every-time I launch Gazebo, there is a default turtlebot that always appears in the simulation although I don't launch him.
There is a black robot (called mobile_base), it appeared although I didn't launch it).
To simplify the problem, even when I am loading just gazebo empty world without my robots, this default robot (mobile_base) appears in the simulation.
Do you have an idea how can I remove this default robot from Gazebo simulation? Thank you!
EDIT: solved by launching different world, that doesn't contain a default turtlebot.
