FIELD: micro-robotics. ^ SUBSTANCE: gripping device includes system of vacuum suction, vacuum source in the form of pneumatic piezo-pump, high-pressure chamber, two valve piezoelectric mechanisms. One of valve mechanism provides communication of main cavity of piezo-pump with atmosphere, other valve mechanisms provides communication of high-pressure chamber with main cavity of piezo-pump. Main cavity of piezo-pump is in the form of hollow piezoelectric transducer. Vacuum suction system is formed by several rows of pneumatic suction units. Each suction unit has along edges of its contact with basing surface elastic collars with high adhesion and high friction properties. Cavities of suction units are communicated with high-pressure chamber through airtight elastic membranes. ^ EFFECT: enlarged functional possibilities due to gripping dusty, rough, porous and complex-relief surfaces, for example having cracks and so on. ^ 5 dwg |
