Abstract: A walking robot having a hydraulic motion control device and a method for controlling the same are provided to improve walking stability of the walking robot by allowing the walking robot to walk according to an orbit of a ZMP(Zero Moment Point). A walking robot having a hydraulic motion control device comprises a pair of foot members(11a,11b), a pair of leg members provided at upper portions of the foot members, thigh members provided at upper portions of the leg members, and pelvic members(50) provided at upper portions of the thigh members. Upper tanks(21a,21b) are installed at upper portions of the pelvic members, intermediate tanks(26a,26b) serving as the thigh members are installed at lower portions of the pelvic members, and lower tanks(27a,27b) serving as the leg members are installed at lower portions of the thigh members. A base frame(40) is located on the pelvic members and a hydraulic tank unit(21) is installed on the base frame. A hydraulic pump(60) is installed at one side of the hydraulic tank unit to supply fluid to the tanks.

Abstract: A method for producing titanium dioxide nanostructure by UV irradiation is provided to need no membrane or additive for forming a nanostructure by virtue of self-assemblage of rod-like or hexahedral titanium dioxide three-dimensional nanostructure. A method for producing titanium dioxide nanostructure by UV irradiation comprises the steps of: (1) dispersing titanium dioxide into an ethanol solution having a pH controlled to 1-4 to obtain titanium dioxide nanoparticle colloid, followed by drying to obtain powder; (2) redispersing the powdered titanium dioxide nanoparticles into an aqueous acid solution having a pH controlled to 1-3 and applying ultrasonic waves thereto to obtain colloid in which nanoparticles are dispersed; (3) irradiating UV rays to the colloid in which nanoparticles are dispersed to activate the surface of the titanium dioxide nanoparticles; and (4) applying the colloid in which surface-activated titanium dioxide nanoparticles are dispersed onto a substrate, followed by drying.
