Major Changes
- TBD
Upgrade Guide
Other changes
Hardware Support
- TBD
Common
- Battery level estimation improvements (PX4-Autopilot#23205).
- Voltage-based estimation with load compensation now uses a real-time estimate of the internal resistance of the battery to compensate voltage drops under load (with increased current), providing a better capacity estimate than with the raw measured voltage.
- Thrust-based load compensation has been removed (along with the
BATn_V_LOAD_DROP
parameters, wheren
is the battery number).
Control
- TBD
Estimation
- TBD
Sensors
- TBD
Simulation
- [SIH]: The SIH on SITL custom takeoff location in now set using the normal unscaled GPS position values, where previously the value needed to be multiplied by 1E7. (PX4-Autopilot#23363).
- [Gazebo]:
- Gazebo Harmonic LTS release replaces Gazebo Garden as the version supported by PX4. The default installer scripts (used for CI) and documentation have been updated. This is required because Garden end-of-life is Nov 2024. (PX4-Autopilot#23603)
- New vehicle model
x500_lidar
— x500 Quadrotor with 2D Lidar. (PX4-Autopilot#22418, PX4-gazebo-models#41). - New vehicle model
r1_rover
— Aion Robotics R1 Rover (PX4-Autopilot#22402 and PX4-gazebo-models#21). - New vehicle model
rover_ackermann
— Ackermann Rover (PX4-Autopilot#23383 and PX4-gazebo-models#46).
Ethernet
- TBD
uXRCE-DDS / ROS2
- TBD
MAVLink
- TBD
Multi-Rotor
- Allow system-default multicopter orbit mode yaw behaviour to be configured, using the parameter MC_ORBIT_YAW_MOD (PX4-Autopilot#23358)
VTOL
- TBD
Fixed-wing
- Improvement: Fixed-wing auto takeoff: enable setting takeoff flaps for hand/catapult launch. PX4-Autopilot#23460
Rover
This release contains a major rework for the rover support in PX4:
- Complete restructure of the rover related documentation.
- New firmware build specifically for rovers (PX4-Autopilot#22675).
- New module dedicated to differential rovers (PX4-Autopilot#22402, PX4-Autopilot#23430 and PX4-Autopilot#23629)
- The module currently supports manual mode, acro mode, stabilized mode, position mode and auto modes.
- New module dedicated to Ackermann rovers (PX4-Autopilot#23024, PX4-Autopilot#23310, PX4-Autopilot#23423 and PX4-Autopilot#23572).
- The module currently supports manual mode and auto modes.
- New module dedicated to mecanum rovers (PX4-Autopilot#23708 and PX4-Autopilot#23834).
- The module currently supports manual mode, acro mode, stabilized mode, position mode and auto modes.
- Restructure of the rover airframe numbering convention (PX4-Autopilot#23506).
This also introduces several new rover airframes:- Generic Differential Rover
50000
. - Generic Ackermann Rover
51000
. - Axial SCX10 2 Trail Honcho
51001
. - Generic Mecanum Rover
52000
.
- Generic Differential Rover
- Library for the pure pursuit guidance algorithm that is shared by all the rover modules (PX4-Autopilot#23387 and PX4-Autopilot#23438).
- Simulation for differential-steering and Ackermann rovers in gazebo (for release notes see
r1_rover
androver_ackermann
in simulation). - Deprecation of the rover position control module: Note that the legacy rover module still exists but has been superseded by the new dedicated modules.
ROS 2
- TBD
