Question: I’m stuck in GTAV Story mode because there don't seem to be any other missions to do. I’ve checked a guide and I know exactly what the next missions should be, but there is no marker on the map. I know I’m using the correct character to trigger the mission and I made sure my phone was on to get important calls.  What should I do? Answer: Some ...

Jan 30, 2020 · PX4 is an open source flight control software for drones and other unmanned vehicles. The project provides a flexible set of tools for drone developers to share technologies to create tailored solutions for drone applications. PX4 is hosted by Dronecode, a Linux Foundation non-profit.
Up until this point in time, however, the PX4 will reject takeoff commands. When I tell the drone to do something it always lands. For example, you use DroneShell moveToPosition -z -20 -x 50 -y 0 which it does, but when it gets to the target location the drone starts to land. This is the default behavior of PX4 when offboard mode completes.

May 21, 2017 · Hey all, Have a quadcopter that slammed into a brick wall on Mission mode this morning and I'm having trouble figuring out why. I think it might be a problem with the GPS? GPSP Alt is cut off, KML file is cut off, but uncertainty seems fine though there is a lot of jamming. It acted strangely just before it accelerated, looping around, dipping to the ground (but reached the take off point ...

The API uses the PX4 Offboard flight mode. The class can only be used with copter and VTOL vehicles (not fixed wing - a PX4 limitation) and currently only supports velocity setpoint commands (PX4 additionally supports position and thrust setpoints). Client code must specify a setpoint before starting Offboard mode. The Offboard plugin ...
The aircraft takes off in the current direction using either catapult/hand-launch mode or runway takeoff mode. The mode defaults to catapult/hand launch, but can be set to runway takeoff using RWTO_TKOFF. In catapult/hand launch mode the vehicle will perform a full throttle climbout (ramp up to RWTO_MAX_THR in about 2 seconds).

You should move/drag the planned home position to roughly the location where you plan to takeoff. The altitude for the planned home position is set in the Mission Settings panel. The Fly View displays the actual home position set by the vehicle firmware when it arms (this where the vehicle will return in Return/RTL mode).

The most promising architectures include multi- and quadrocopters, tilt-wingers, electrical vertical take-off and landing (eVTOL) aircrafts as well as hybrid constructions. While the former types are particularly suitable for inner-city operations in confined spaces, the fast flying vertical starters are ideal for use between longer distances.
Hold Mode. The Hold flight mode (a.k.a. "Loiter") causes the vehicle to stop and maintain its current GPS position and altitude (MC vehicles will hover at the GPS position, while FW vehicles will circle around it).. Hold mode can be used to pause a mission or to help you regain control of a vehicle in an emergency. It is usually activated with a pre-programmed switch.

Oct 11, 2020 · Unfortunately there is a small set of commands that are either ArduPilot-only or PX4-only. Your issue is one such example - the c_uart_interface_example uses the PX4 OFFBOARD flight mode. To work with ArduPilot, the example would have to be changed to instead use the more generic GUIDED flight mode.
The takeoff process is rec ommended as follow, press i to increase the upward speed to 0.3, then press b to switch off board mode, and finally press t to unlock. Note that mavros topics and services are preceded by the name of the UAV, such as /iris_0/mavros/state.

To takeoff (when landed): Press the Takeoff button in the Fly Tools (this will toggle to a Land button after taking off). Optionally set the takeoff altitude in the right-side vertical slider. Confirm takeoff using the slider.
PX4 is one of the open-source drone firmware you can run on a Pixhawk. It allows to fly fixed wings, copters (any configuration), vertical_takeoff and driver rovers. It provides ROS1 (mavros) and ROS2 (micrortps) integrations and is one of the leading software for autonomous drones.
Modify take off and landing. Update TAKEOFF parameters. Alt must be at least 100. You must have an approach WAYPOINT, 35m Altitude, 600 ft (120m), down wind, from your LAND waypoint. You can right-click on the map to insert waypoints and use the Up Down arrows to move the waypoints. Select Write WPs to copy the mission to your UAV Mapper.

On fixed-wing vehicles PX4 will not automatically take off (the autopilot will detect the lack of movement and set the throttle to zero). The vehicle may start executing the mission if hand- or catapult- launched while in mission mode. If no mission is stored, or if PX4 has finished executing all mission commands:
