Aerial vehicles with uncoupled degrees of freedom

An aerial vehicle (1) comprises a main frame (3) and a plurality of operable multicopter units (2a-d). Each multicopter unit has a plurality of propulsion units (5). The propulsion units (5) are attached to the respective multicopter unit (2a-d) at a fixed roll angle, a fixed pitch angle and a fixed yaw angle. The plurality of operable multicopter units (2a-d) are attached to the main frame (3) by interposition of respective joints (4) and rotate relative to the main frame (3) independently to each other. At least one of the joints (4) has a minimum of one degree of freedom, such that the main frame (3) has a at least the same or higher number of controllable degrees of freedom than the total number of degrees of freedom of the main frame (3).
