MOBILE PIEZOELECTRIC MICROROBOT Russian patent published in 2001 - IPC

FIELD: mechanical engineering; microsystem manufacture. SUBSTANCE: microrobot has moving platform and piezoelectric transducers positioned at apexes of equilateral triangle. Micromanipulating system has spherical base, permanent magnet, and piezoelectric transducers forming Cartesian coordinate system. Platform drive is piezoceramic tubular member carrying one internal and four external evaporated electrodes arranged symmetrically. One end of piezoceramic tubular member is connected to bushing with slots carrying wires. Other loose end of piezoceramic tubular member mounts ruby ball fixed thereon by adhesive. Piezoelectric transducers of micromanipulating system have one internal and two external evaporated electrodes arranged symmetrically to form Cartesian coordinate system. EFFECT: enhances capacity of microrobot, enlarged functional capabilities of micromanipulating unit. 7 dwg
