## Description

Rotors Simulator is a physics-based simulation framework designed for testing multirotor unmanned aerial vehicles and their control algorithms within a virtual environment. It models aerial vehicle movement, rotor thrust, and aerodynamic interactions by computing individual motor speeds directly to apply thrust and torque forces to rigid body dynamics. Aircraft kinematics, visual meshes, and sensor attachment points are described declaratively using unified robot description format files.

The environment integrates dynamic models and aerodynamic forces through native runtime plugins while coordinating simulation physics and control loops using publish-subscribe messaging and service calls. Virtual hardware components stream telemetry and perception streams over standard messaging channels to emulate physical onboard instruments. Additionally, the simulation supports manual flight commands sent through physical joysticks or keyboards mapped to aircraft control axes.
