<p>A miniaturized microrobotic device for autonomous locomotion in a liquid environment, comprising a control unit (8) and a power source (2), containing means for generating a variable magnetic field (4, 5) and flexible elements (6) arranged along the external surface of its housing and fixed with one of their ends (6a) to said housing. The opposite end of the flexible elements is free to move and has a magnetised or magnetisable portion (6b), interacting with said variable magnetic field to cause a reciprocating bending and elastic backward, radial movement of the flexible elements (6), said movement generating thrust forces on the surrounding liquid capable of producing the device propulsion.</p> |
