![]() Simulated optical flow from a flow sensor (e.g. Simulated IMU readings in SI units in NED body frame. PX4 control outputs (to motors, actuators). All motors/actuators are blocked, but internal software is fully operational. ![]() MAV_MODE:MAV_MODE_FLAG_HIL_ENABLED (opens new window) The messages are described below (see links for specific detail). Sensor data from the simulator is written to PX4 uORB topics.Īll motors / actuators are blocked, but internal software is fully operational. This API defines a set of MAVLink messages that supply sensor data from the simulated world to PX4 and return motor and actuator values from the flight code that will be applied to the simulated vehicle.Ī SITL build of PX4 uses SimulatorMavlink.cpp (opens new window) to handle these messages while a hardware build in HIL mode uses mavlink_receiver.cpp (opens new window). # Simulator MAVLink APIĪll simulators except for Gazebo communicate with PX4 using the Simulator MAVLink API. It is not required to use the simulators. The remainder of this topic is a "somewhat generic" description of how the simulation infrastructure works. There are also a number of Community Supported Simulators. It can also be used for multi-vehicle simulation. It is easy to set up and can be used to test that your vehicle can take off, fly, land, and responds appropriately to various fail conditions (e.g. Supported Vehicles: Quad ( Iris, Hex (Typhoon H480), Generic Standard VTOL (QuadPlane), Tailsitter, Plane, Rover, SubmarineĪ simple multirotor simulator that allows you to fly copter type vehicles around a simulated world. Supported Vehicles: Quad, Standard VTOL, Plane ![]() It can also be used for multi-vehicle simulation and is commonly used with ROS, a collection of tools for automating vehicle control. It is the only version of Gazebo available from Ubuntu Linux 22.04Ī powerful 3D simulation environment that is particularly suitable for testing object-avoidance and computer vision. Gazebo supersedes Gazebo Classic, featuring more advanced rendering, physics and sensor models. The following simulators are supported by the PX4 core development team. The other sections provide general information about how the simulator works, and are not required to use the simulators. Information about available simulators and how to set them up are provided in the next section. PX4 supports both Software In the Loop (SITL) simulation, where the flight stack runs on computer (either the same computer or another computer on the same network) and Hardware In the Loop (HITL) simulation using a simulation firmware on a real flight controller board. It is also a good way to start flying with PX4 when you haven't yet got a vehicle to experiment with. No misleading, undescriptive, clickbait or self-deprecating titles.ġ1.Simulation is a quick, easy, and most importantly, safe way to test changes to PX4 code before attempting to fly in the real world.
