Study of the method of trajectory and sequential deformations simultaneous planning for a tensegrity drone

Abstract

Modern aerial robots, in particular the drones, are developing at a rapid pace. Drones appear to be a promising area in robotics performing dangerous tasks during search and rescue operations, as well as in practical applications such as photography and cinematography. An urgent task is to ensure the drone safety against their mechanical damage when interacting with the external environment, as well as the safety of people in case of contact with the drones. To solve this problem, it is advisable to use tensegrity drones with the deformable structure and the ability to adapt to the changing environment parameters taking into account the obstacles encountered in the flight. These drones are able to ensure the controlled deformation of their fuselage in flight making them more mobile in difficult environments. A method was previously proposed to plan such trajectories based on solving the optimization problem with the linear matrix inequalities. However, numerical properties of the method remained unexplored. The problem of planning the tensegrity drone flight was considered. Numerical experiments were carried out. It was established that the surrounding space geometry had insignificant effect on the task implementation, but very significantly affected computational complexity and elapsed processor time.
