Motion and path planning of drone in V-REP. A robotics simulator is a simulator used to create application for a physical robot without depending on the actual machine, thus saving cost and time. In Groovy and Fuerte, the core simulator code is pulled in and wrapped inside the gazebo package. ROS releases may be incompatible with other releases and are often referred to by code name rather than version number. The work presented here follows the same baseline structure displayed by researchers in the OpenAI Gym, and builds a gazebo environment. ROS with Gazebo Simulation. To check any topic we need to have the simulations running, we need to do two things: 1) Unpause the simulation: without that th stream of data doesnt flow.
