Previously discussed here : Offboard automatic TakeOff / Landing using MAV_CMD_LAND/TAKEOFF_LOCAL - #5 by tdo From the Mavlink receiver implemented in the PX4 Firmware, we can read that there are undocumented features for the SET_POSITION_TARGET_LOCAL_NED mavlink message. We can see there are a Ta…

I tested that enum under Gazebo 7, with PX4 Firmware 1.5.5 enum TypeMasks { MASK_POSITION = 0b0000111111111000, MASK_VELOCITY = 0b0000111111000111, MASK_TAKEOFF_POSITION = 0b0001111111111000, MASK_TAKEOFF = 0b0001111111111111, MASK_LAND_VELOCITY = 0b0…

Hello, I’m still using version 1.4.4 but I will switch to 1.5.5 As I’m landing using Offboard command, i’m using this bitmask : (0x2000 | 0b110111000011). I also set null speed for vx and vy (even if its redundant with bitfield, just to make sure) nedSetpoint->vx = 0; /* Set Null Speed for x …

Hi, Do you mean that if i where OFFBORAD, (e.g Raspberry pi connected to Pixhawk). I should use the following message SET_POSITION_TARGET_LOCAL_NED to take off?? Can I do it simply by using MAV_CMD_NAV_TAKEOFF?? Thanks

My method is to send a velocity setpoint of 0.5m/s up to 1m/s

The AUTO TAKEOFF is a part of the Waypoint system (GPS Waypoints)
