摘要:
A supplementary support structure, which supports the body of a robot (1), comprises a contact component (7) which is disposed in a part near a joint (2c) on the distal end, having a hand (3) disposed thereon, of an arm (2) of the robot (1) so as to come into contact with a surface on which the robot (1) is supported, such as a floor surface, and a member which lies between the part having the contact component (7) disposed therein and the proximal end of the arm (2). Thus, the supplementary support structure can avoid an increase in the weight of the hand resulting from the support structure, thus eliminate an extra load on a driving system for the hand or the arm, and thus achieve the simplification and size reduction of the driving system. Moreover, the support structure can increase the degree of freedom of the shape or functional design of the hand and thus improve the functioning of the robot.

A method for detecting a low rigid force and a device therefor are provided in that even a large impact force is applied, by integrating an impact absorbing unit with the force detection mechanism, a force detection mechanism may not be damaged. To that end, between a pair of substrates 2a and 2b opposing each other and undergoing displacement in a direction changing the space between them by an impact force applied thereto, at least one absorption detection mechanism 3 integrally including an impact absorbing unit 4 and a force detecting unit 5 is interposed, so that a force applied between both the substrates 2a and 2b is detected by the force detecting unit 5 while an impact force applied between both the substrates 2a and 2b being absorbed by an elastic force of the impact absorbing unit 4.

An object of the present invention is to provide a gait pattern generating device by which a gait pattern of a robot such as a humanoid bipedal walking robot having a structure easy to fall down can be generated easily in real time. This device calculates a driving quantity of the center of gravity in one moment using a preview control method based on feedback of the motion state of the center of gravity in that moment, and feed-forward of a future ZMP trajectory up to a few seconds from that moment. Next, the robot is driven to obtain the obtained center-of-gravity trajectory. Thus, a walking motion is attained.

The present invention provides a walking control method and a walking control apparatus for achieving stable attitude control of a legged robot. In the walking control of the legged robot, basically, a foot-sole coordinate system based on sole positions and having at least a first coordinate axis in a direction connecting soles of both legs and a second coordinate axis perpendicular to the first coordinate axis in a horizontal plane is used as a control coordinate system, and attitude control is performed with different control characteristics for the first and second coordinate axes. Accordingly, the legged robot includes sole position sensors for detecting the sole positions of ground-contacting legs, ground contact sensors for detecting the state of the ground-contacting legs or a motion controller for generating the state of the ground-contacting legs, a control device which performs the walking control using a coordinate system based on the direction connecting the soles of the legs as a control coordinate system in accordance with the detected sole positions and the state of the ground-contacting legs, and leg actuators controlled by the control device.

A pressure-sensitive adhesive double-coated sheet comprising a substrate, a pressure-sensitive adhesive layer (A) formed on one side of the substrate and a pressure-sensitive adhesive layer (B) formed on the other side of the substrate, wherein at least the pressure-sensitive adhesive layer (A) is formed with a pressure-sensitive adhesive comprising a butyl rubber as base material, and after the pressure-sensitive adhesive double-coated sheet is allowed to stand at 60° C. for five days while being placed between a moisture vapor-permeable waterproof sheet attached to the adhesive layer (A) and an aluminum plate attached to the adhesive layer (B), an expansion coefficient of the moisture vapor-permeable waterproof sheet is 0.5% or less. The pressure-sensitive adhesive double-coated sheet can allow the moisture vapor-permeable waterproof sheet to less expand over time when attached between the moisture vapor-permeable waterproof sheet and the adherend in a waterproof airtight structure of a construction.

摘要:
A method of working metal in which the microstructure of metal body is rendered fine to thereby enhance the strength, ductility or homogeneity thereof; a metal body obtained by the metal working method; and a metal-containing ceramic body obtained by the metal working method. In this metal working method, the deformation resistance of metal body or metal-containing ceramic body (hereinafter referred to simply as “metal body”) is lowered locally to thereby form low deformation resistance regions in the metal body, and shear deformation of the low deformation resistance regions is effected so as to fine the microstructure of metal body. In particular, the metal body is formed in unidirectionally drawn configuration so as to produce low deformation resistance regions crossing the metal body. Further, with respect to two non-low deformation resistance regions arranged to sandwich low deformation resistance region crossing the metal body, one non-low deformation resistance region is caused to have a relative position change to the other non-low deformation resistance region so as to effect shear deformation of the low deformation resistance region. The low deformation resistance regions can be moved along the direction of drawing of the metal body.
