摘要:
The lumbar part of a robot as a controlled-object point where the mass is moved to the largest extent is set as the origin of a local coordinate, an acceleration sensor is disposed at the controlled-object point to directly measure the attitude and acceleration at that position to control the robot to take a stable posture on the basis of a ZMP. Further, at each foot which touches the walking surface, there are provided a floor reaction force sensor and acceleration sensor to directly measure a ZMP and force, and a ZMP equation is formulated directly at the foot nearest to a ZMP position. Thus there can be implemented a stricter and quick control of the robot for a stable posture.
摘要:
A ZMP equilibrium equation stating the relationship of various moments applied to a robot body of a robot, based on desirable motion data made up by trajectories of respective parts, imaginarily divided from the robot body, is generated, and moment errors in a ZMP equilibrium equation are calculated. A priority sequence of the parts, the target trajectories of which are corrected to cancel out the moment errors, is set. The target trajectories are corrected from one part to another, in a sequence corresponding to the priority sequence, to compensate the moment errors.

A vehicle approach alert device for a saddle-ridden electric vehicle is a vehicle approach alert device for a saddle-ridden electric vehicle that is provided with a sound emitter that is attached on the vehicle body of a saddle-ridden electric vehicle having an electric motor in a power engine, and that emits an alert sound to a surrounding area for notifying the surrounding area of approach of the saddle-ridden electric vehicle, such that sound emission of the sound emitter is controlled, and the sound emitter is arranged so that the direction of sound emission is oriented diagonally downward and forward of the saddle-ridden electric vehicle.
摘要:
In a sheet finisher which receives a sheet from an image forming apparatus, conducts a sheet finishing onto the sheet and feeds out the sheet, the sheet finisher includes: a stacking section which stores temporarily one or more sheets; and a sheet finishing section which conducts the sheet finishing onto the sheet stored in the stacking section. The stacking section having a first guide member which forms a stacking surface to guide the sheet, and a second guide member which faces the first guide member and is spaced apart from the first guide member by a predetermined distance, and is provided obliquely from a horizontal direction, and the stacking surface formed by at least a part of the first guide member, is formed to be curved in a direction perpendicular to a sheet conveyance direction.
摘要:
There is provided a control apparatus including a function of generating an operation signal applied to a control subject and a model that simulates characteristics of the control subject, a function of receiving an evaluation value signal calculated based on a measurement signal obtained by applying the operation signal to the control subject and the model, and a function of learning to generate the operation signal such that an expected value of the sum of the evaluation value signals obtained from a present state to a future state is either maximum or minimum in which the evaluation value signal calculated based on the measurement signal from the model is calculated by adding a first evaluation value obtained based on a deviation between the measurement signal obtained from the model and a setpoint value, and a second evaluation value obtained based on a difference in characteristics between the model and the control subject.

A two-wheeled motor vehicle (10) provided with a throttle grip (25) rotated by the driver to change the degree of opening of a throttle valve (31), and also with an exhaust valve (34) which, when a throttle ratio which is a ratio of the angle of operation of the throttle grip to the maximum rotation angle of the throttle grip is between zero and a predetermined value, reduces noise emitted from an engine.
