  • Patent number: 7606634
    Abstract: Ground contact portions 10 are classified into a tree structure such that each of the ground contact portions 10 of a mobile body 1 (mobile robot) equipped with three or more ground contact portions 10 becomes a leaf node and that an intermediate node exists between the leaf node and a root node having all the leaf nodes as its descendant nodes. On each node (a C-th node) having child nodes, the correction amounts of the desired relative heights of the ground contact portions 10 of the C-th node are determined such that the relative relationship among the actual node floor reaction forces of the child nodes of the C-th node approximates the relative relationship among the desired node floor reaction forces of the child nodes of the C-th node, and joints of the mobile body 1 are operated so that a desired relative height obtained by combining the correction amounts is satisfied.

  • Publication number: 20090196717
    Abstract: An apparatus and method of handling substrates is disclosed. A detecting system, capable of determining whether a substrate is tilted in relation to the platen, is positioned proximate to the substrate. In some embodiments, the detecting system is a distance measuring system. In other embodiments, it is an angle sensor. The detecting system is in communication with a controller, which, in turn, is in communication with a substrate handling robot. If, based on information received from the detecting system, the controller determines that the substrate is tilted beyond an acceptable range, it is assumed that the substrate has remained attached to the platen. In such a case, the substrate handling robot does not attempt to remove it from the platen. In this way, the substrate is not damaged.

  • Patent number: 7571025
    Abstract: A method for controlling a plurality of manipulators, such as multiaxial or multiaxle industrial robots. At least one manipulator functions as the reference manipulator and is moved in a plurality of preset poses within its working area at which internal position values are determined as first desired poses. For each desired pose, subsequently a first actual pose of the reference manipulator is determined by an external measuring system. Subsequently at least one further manipulator moves up to specific poses of the reference manipulator as second desired poses and for each of these poses an actual pose of the further manipulator is determined by an external measuring system. On the basis of actual-desired deviations between the thus determined desired and actual poses of the two manipulators, subsequently a parameter model for the further manipulator is established and with it it is possible to compensate simultaneously both its own errors and those of the reference manipulator.

  • Patent number: 7386364
    Abstract: A legged mobile robot gives up a normal walking motion and starts a tumbling motion when an excessively high external force or external moment is applied thereto and a behavior plan of a foot part thereof is disabled. At this time, the variation amount ?S/?t of the area S of a support polygon of the body per time t is minimized and the support polygon when the body drops onto a floor is maximized to distribute an impact which acts upon the body from the floor when the body drops onto the floor to the whole body to suppress the damage to the body to the minimum. Further, the legged mobile robot autonomously restores a standing up posture from an on-floor posture thereof such as a supine posture or a prone posture.

  • Patent number: 7379789
    Abstract: A permissible range of a restriction object amount, which is a vertical component of a floor reaction force moment or a component of the floor reaction force moment in floor surface normal line direction, or a vertical component of an angular momentum changing rate of the robot or a component of the angular momentum changing rate in floor surface normal line direction, is set, and at least a provisional instantaneous value of a desired motion is input to a dynamic model so as to determine an instantaneous value of a model restriction object amount as an output of the dynamic model. An instantaneous value of a desired motion is determined by correcting the provisional instantaneous value of the desired motion such that at least the instantaneous value of the model restriction object amount falls within the permissible range.

  • Patent number: 7366587
    Abstract: The characteristics of actuators themselves and the characteristics of controllers for the actuators are dynamically or statically controlled to achieve stable and highly efficient movements. In a stage in which a leg in the flight state is uplifted such that the reactive force from the floor received by the foot sole of the leg is zero, the characteristics of the respective actuators for the knee joint pitch axis and the ankle pitch and roll axes of the leg in the flight state are set for decreasing the low range gain, increasing the quantity of phase lead and for decreasing the viscous resistance of the actuators, in order to impart mechanical passiveness and fast response characteristics. The followup control for the high frequency range may be achieved as the force of impact at the instant of touchdown is buffered.

  • Patent number: 7337040
    Abstract: Based on a detected or estimated value of an actual posture of a predetermined part, such as a body 3, of a robot 1 and a deviation the actual posture from a posture of a desired gait, a posture rotational deviation's variation is determined as the temporal variation of the deviation, and the position of the robot 1 (for example, the position where the robot comes into contact with a floor) is estimated on the assumption that the robot 1 rotates about a rotation center by the rotational deviation's variation. In addition, in accordance with the difference between the estimated position and the estimated position of the robot 1 determined by an inertial navigation method using an accelerometer or the like, the estimated position of the robot 1 determined by the inertial navigation method is corrected, thereby improving the precision of the estimated position.

  • Patent number: 7328087
    Abstract: A bipedal robot of the present invention has a trunk consisting of an upper trunk and a lower trunk which are rotatable around a rotation axis relative to one another. The upper trunk has shoulders on the right and left sides. An arm is provided at each shoulder. A pair of right and left legs is attached to lower ends of the lower trunk. A storage battery is mounted to the back of the upper trunk, positioned within a shoulder width. The storage battery is positioned below the top of a head mounted on the upper trunk. When the robot walks a narrow passage or corridor having a width slightly larger than the width thereof, for example, this arrangement prevents the storage battery from interfering with the passage or the like.

  • Patent number: 7324871
    Abstract: A fully integrated system and method that provides for a system that generates fundamental differences between a host system and sensory data. The system processing covers a series of contrasting sensory data ranges that are comprised of sensory streams, sight, sound, temperature, etc. The ranges establish a point of reference within a host system for contrast with external sensory data. A static range of the system is contrasted with the active range producing an impact variation (a measurable difference) between the ranges. The processing effected by the system utilizes the monitored impact variations resulting from the contrasting sensory ranges, in conjunction with multiple sensory stream integration to resolve the problem of retaining sensory data objectivity when sensory data is internalized by a system.

  • Patent number: 7319919
    Abstract: A landing position/orientation of a foot (22) to be landed in a landing action of a robot (1) such as a biped mobile robot or the like is estimated, and a desired footstep path for the robot (1) is set up. Based on the estimated landing position/orientation and the desired footstep path, a future desired landing position/orientation is determined in order to cause actual footsteps of the robot (1) (a sequence of landing positions/orientations of the foot (22)) to approach desired footsteps. Using at least the determined desired landing position/orientation, a desired gait for the robot (1) is determined, and the robot (1) is controlled in operation depending on the desired gait. For determining the desired landing position/orientation, mechanism-dependent limitations of the robot (1) such as an interference between the legs thereof, etc., and limiting conditions of an allowable range in which a desired ZMP can exist are taken into consideration.
