Abstract:
Unmanned Ariel vehicles are needed more and more everyday due to their
ability to reach places and do tasks that are hard for human to reach and to do.
Drone can face some challenges such as the short life of the battery or the
environmental special conditions (obstacles, rough weather…) or just to be
liberated from it six degrees of freedom.
These special conditions of the drone working environment can prevent it from
doing it tasks, functioning correctly or even lead to it total fail.
To avoid such damages scientists and engineers had the urge to make some new
kind of drones, the transformable drones.
Transformable drones or reconfigurable drones are the drones that can changes
their morphology In order to adapt with the external environment.
We chosed the study of foldable drones more specifically horizontally rotating
arms quadrotor. Using both mathematical and numerical models to represents
the different configurations of the foldable quadcopter, we obtained little
different results what was expected due to the use of two different models but
the common things about the results is the results of both models represent
steady states of the quadcopter and both model results tend to follow the pattern
of the trajectory given as an input.
