Abstract

The invention relates to a vectored-thrust vehicle comprising: a chassis; at least two thrusters mounted on the chassis, each thruster being mounted so as to be able to rotate on the chassis about two orthogonal axes of rotation and each thruster being able to exert thrust in a direction defined by the angle of rotation of the thruster about each of these axes of rotation; at least two drive systems each associated with one of the thrusters and capable of rotating that thruster about one and/or the other of the axes of rotation; a unit for controlling the drive systems, characterized in that, upon receipt of a navigation instruction, the control unit is designed to determine, from the navigation instruction, a thrust vector for each of the thrusters comprising a first component, referred to as the force component, generating a thrust corresponding to a force setpoint of the navigation instruction, a second component, referred to as the moment component, generating a thrust corresponding to a moment setpoint of the navigation instruction and a third component, referred to as the thrust offset component, the value of which is dependent on the attitude of the vehicle, the control unit being designed to control the drive systems associated with each thruster on the basis of the thrust vector determined for this thruster.
