Abstract

A fluidic actuator includes a chamber filled with a fluid, an element movable in relation to the chamber and in contact with the fluid, as well as a passage for circulating the fluid between the inside and the outside of the chamber in order to vary the amount of fluid in the chamber, thus causing movement of the movable element. The fluid is magnetorheological and the fluidic actuator includes a magnetic field generator arranged so as to generate, in the passage, a controlled magnetic field.
