Abstract
In one example, an actuator mechanism comprising: one or more coils for establishing a magnetic field; a rotating permanent magnet, which has at least one extreme position depending on the magnetic field; and driving members, which are coupled to the permanent magnet and by means of which the members coupled to the actuator mechanism are driven. In another example, an actuator mechanism comprising: one or more wires, which are manufactured of a shape memory alloy that shrinks when heated; and driving members, which are coupled to said wire and by means of which the members connected to the actuator mechanism are driven.
