Abstract

Disclosed are a micro electro-hydraulic linear actuator and a hand of an electro-hydraulic driving robot, comprising an actuator base, a spherical pump unit and a reciprocating piston mechanism encapsulated in a closed elastic leather bag. The actuator base is provided with a hydraulic cylinder and a cylinder liner, both of which are cylindrical chambers with an open at one end. An open end of the hydraulic cylinder is provided with an end cover of the hydraulic cylinder, an open end of the cylinder liner is provided with an end cover of the motor, the reciprocating piston mechanism is provided in the hydraulic cylinder, and the spherical pump and motor are integrated in the cylinder liner to form a spherical pump unit; the present application adopts a distributed hydraulic source as the driving force and does not need a directional valve.
