MOBILE PIEZOELECTRIC VACUUM MICROROBOT Russian patent published in 2003 - IPC

FIELD: mechanical engineering. SUBSTANCE: microrobot designed for precision displacement of parts over inclined, vertical, or overhead surfaces by using vacuum grips installed on its drive has mobile platform and actuator in the form of main piezo-crystal carrying on its ends first and second vacuum grips. Vacuum grip is essentially an assembly of pneumatic sucker and piezoelectric air-lift pump. Piezoelectric pump has damping member made in the form of power piezo-crystal and flexible structural member made in the form of flexible cylinder. Main cavity of piezoelectric air-lift pump is isolated from its external space and from pneumatic sucker cavity by means of first and second valves, respectively, which are essentially first and second distributing piezo- crystals. Pneumatic sucker is held tight against positioning surface. EFFECT: enlarged functional capabilities. 1 cl, 4 dwg
