METHOD AND APPARATUS TO CONTROL HYDRAULIC MANIPULATOR Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: process of working unit movement in space, using joint regulation of angular movements of arm and forearm, is exercised by feeding of working fluid from cavity of hydraulic cylinders of arm 3 turning to similar cavity of hydraulic cylinder 4 of forearm 5 turning or vice versa in case angle α₂ of forearm turning is twice as big as angle α₁ of arm turning and total cross section area of arm turning both cylinders similar cavities also is twice as big as cross section area of similar cavities of hydraulic cylinder 4. EFFECT: method and apparatus are used in mechanical engineering. 2 cl, 2 dwg
