4/2/2023 0 Comments Autonomous quad copter![]() Some folks love the thrill of flying and controlling everything manually. That means you can exploit them if you want to or take back control if you don’t. Most autonomous features are also optional. When Autonomy Gets Boringĭrones at the consumer level are not 100% autonomous and still need a pilot’s input at some point. There are others, and we know there will be new and exciting additions to the existing ones in the times ahead. OK, these are some of the most popular autonomous drone features. Waypoints are especially useful when flying and filming along otherwise complex routes. It’s also possible to save favorite flight paths for future use should you want to revisit them. Pilots can then focus on shooting with the camera as the drone cruises between its waypoints. It’s possible to get the drone to fly in specific ways at the various waypoints like altitude and speed. You can also set waypoints along a cable cam (see above). The positioning technology used for waypoints guides the drones. Waypoints are typically a set of predefined coordinates in the air. The flying camera then hovers into position on demand and takes stills or video at the correct exposure. Selfie modes vary, but they all work by instructing the drone to film or photo the subjects. There are even quadcopters that the makers promote as selfie drones, especially the palm-sized models. Selfie mode is vital in a world gripped with self-portraiture and social media. Aerial videography doesn’t get much easier than that. The quadcopter needs no flight assistance as it auto flies to its predefined destination. The pilot is then free to focus on the camera and capture footage without worrying about the drone. The user creates the “cable” by selecting a point A and point B (destination). And if the craft is heading out of range, then it’s a great way to prevent flyaways.Ĭable Cam is a virtual cable through the sky that the drone attaches to. It’s a useful feature if a pilot loses control-or is about to lose control-of the drone. The drone obeys the command and comes back to its original takeoff position. A one-key action from the remote controller (RC) typically triggers RTH. Return to Home (RTF) is an invaluable autonomous drone flight feature. The aerial footage produced by tracking subjects can be awe-inspiring. You often see it used in action events and sports. A drone automatically follows and films a predefined moving subject in this mode. Here’s a simple breakdown of how these autonomous modes make life simple for pilots.įollow Me came around in 2016, and the technology has gotten better ever since. How Autonomous Flight Modes Assist Pilots The list below shows some of the most common autonomous flight features. These independent systems exist to make piloting easier and more enjoyable. Even basic models come with a bunch of novice-friendly flight features. Today, quadcopters (4 props) are the most common of the multirotor aircraft. rviz from ROS is used for visualization on PC.Easy to fly, 4K video, gimbal camera, long flight time, long range, low noise, fast.įlying drones whether for fun, aerial filming, or racing is not as arduous as it used to be. The desktop PC is used only for configuration and visualization purposes. The Flight Controller and the Raspberry Pi 3 on the quadcopter are connected via serial port whereas the Rapsberry Pi 3 and the desktop PC are connected via WiFi. The messages SET_GPS_GLOBAL_ORIGIN and a SET_HOME_POSITION are sent with a script before starting to use the system. The ROS node raspicam_node publish camera/image and camera/camera_info topics, the node aruco_gridboard subscribes to these topics and publish a camera_pose message to the mavros/vision_pose/pose topic, mavros translates ROS messages in MAVLink messages and send it to the Flight Controller. All this ROS packages, and other we will see later, runs on the Raspberry Pi 3. ![]() The images from Raspberry Pi Camera are captured by raspicam_node, the poses estimation are calculated by a modified version of aruco_gridboard and the relevant messages are sent to the Flight Controller using mavros. The system uses ROS for all the tasks it has to do. The camera is downward looking and on the floor there is an Aruco Boards like this: Images from camera are used to calculate poses estimation on the Raspberry Pi and the result are sent as MAVLink messages to the Flight Controller. The system is based on a quadcopter with a Raspberry Pi 3 and a Raspberry Pi Camera Module v2. This wiki page describes how to setup a system capable to realize indoor autonomous flight.
