By providing a moving body with a high-accuracy attitude detection mechanism including a pair of a first rate gyroscope for detecting the attitude of the moving body and a second rate gyroscope which obtains an output inverted from that of the first rate gyroscope and the variations in the outputs of the rate gyroscopes are mutually compensated for, thereby accurately detecting the attitude information of the moving body.

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.

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.

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.

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.

Expression of a desired gene and production of a product from the desired gene can be obtained effectively by cultivating a microorganism containing a hybrid plasmid comprising the desired gene, a vector and a promoter in its cell, and adding an inducer and a nutriment simultaneously to the culture medium at the time when the nutriment originally present in the culture medium is almost consumed.

The invention discloses a free-flow electrophoretic separation method and apparatus for separating charged substances such as proteins, cells, and the like, by electrophoresis, which comprises supplying a mixed solution containing the charged substances to be separated, which are dissolved in a separation buffer, into a separation chamber, circulating the mixed solution inside the separation chamber, applying a d.c. voltage to the mixed solution to cause the electrophoresis of the charged substances and to separate them, and withdrawing the charged substances thus separated from outlets disposed at one and the other end of the separation chamber.
摘要:
A fuel injection valve coupled to a common rail is provided. When fuel injection is carried out, the fuel pressure in the fuel injection valve pulsates. An interval between a pilot injection and a main injection is set so that the main injection is carried out at a zero gradient timing as a timing when the gradient of the fuel pressure in the fuel injection valve after the pilot injection is approximately equal to zero. Owing to a fuel injection control apparatus and a fuel injection control method for an internal combustion engine that perform the above-mentioned control, the fuel injection amount for the subsequent fuel injection following the preceding fuel injection can be reliably held equal to a normal amount.
