title: Note: Development of a compact electromagnetic hydraulic pump for a microrobot joint driving system.
abstract: This note describes a compact electromagnetic hydraulic pump (EMHP) designed primarily to build a microdriving system for a robot joint actuator. A characteristic mathematical model integrating electricity, magnetism, and hydraulics is constructed to represent the working process of the EMHP. Tests show that a volumetric flow rate of up to 430 cm(3)/min and load pressure of up to 2.5 MPa can be achieved. The prototype pump can supply stable pressure of 0-2.4 MPa and acceleration of 1.2 MPa/s for the robot joint actuator.
