Are you trying to during a specific landing maneuver, or are you encountering a script error when trying to assign a value to a pitch variable?
When a vehicle is in or has detected it is on land , the flight controller locks down many attitude controls to prevent "ground loops" or tip-overs. For developers, this means: no set pitch on land.lua
: Once the landing logic initiates, the autopilot typically ignores horizontal and pitch velocity adjustments from scripts to maintain a vertical descent and stable touchdown. Workarounds for Scripting Pitch Are you trying to during a specific landing
: Instead of using the native LAND mode, scripts can use GUIDED mode to send specific position or velocity targets. The Copter Commands in Guided Mode allow for more granular control over heading and turn rates, though vertical control still prioritizes landing safety. Workarounds for Scripting Pitch : Instead of using
Lua Script Test: Setting Horizontal Velocity During LAND Mode
: For complex maneuvers (like a "wander" orbit or precise touchdown angle), some developers disable the default AI and write their own PID controllers in Lua to translate orientation into raw Yaw/Pitch/Roll instructions. Key Resources for Lua Developers
In the context of ArduPilot Lua scripting, there is no simple vehicle:set_pitch() function for a landed state because the autopilot's internal takes priority over external inputs to ensure safety and stability. The "No Set Pitch" Challenge
