|
### Description
|
|
|
|
This module provides a simulator for quadrotors and fixed-wings running fully
|
|
inside the hardware autopilot.
|
|
|
|
This simulator subscribes to "actuator_outputs" which are the actuator pwm
|
|
signals given by the control allocation module.
|
|
|
|
This simulator publishes the sensors signals corrupted with realistic noise
|
|
in order to incorporate the state estimator in the loop.
|
|
|
|
### Implementation
|
|
|
|
The simulator implements the equations of motion using matrix algebra.
|
|
Quaternion representation is used for the attitude.
|
|
Forward Euler is used for integration.
|
|
Most of the variables are declared global in the .hpp file to avoid stack overflow.
|
|
|
