  • Patent number: 7888900
    Abstract: A robot arm is provided with an end effecter for grasping an object and a force sensor for detecting a force acted upon the end effecter. In the state in which end effecter grasps an object, when there is a change in the force acting on the end effecter detected by the force sensor, outputted is a signal for releasing the force of the end effecter grasping the object. The object grasped by the end effecter can be taken out as if the object were handed from person over to person.

  • Patent number: 7873436
    Abstract: When the placement of the elements (mass points, links having inertia, etc.) of a model expressing a robot 1 is determined according to a first geometric restrictive condition from an instantaneous desired motion of the robot 1 that has been created using a dynamic model, this placement is defined as a first placement, and the placement determined according to a second geometric restrictive condition from a corrected instantaneous desired motion that has been obtained by correcting the instantaneous desired motion is defined as a second placement. The corrected instantaneous desired motion is determined such that the moment component calculated from the difference between the first and the second placements approximates a predetermined value. The instantaneous desired motion is created using a dynamic model of the robot.

    Abstract: A mechanism for empirically deriving the values of the damping ratio and frequency of the mechanism driven by a servo-controlled control system is disclosed. In accordance with the illustrative embodiment, the values of the damping ratio and frequency are continually re-generated based on empirical data derived from sensor feedback of the maximum-amplitude switch and the linear second-order servo. Because the values of the damping ratio and frequency are generated from empirical data, it is not necessary that they be known, and because the values of the damping ratio and frequency are continually re-generated, variances in their values are continually noticed and compensated for.

    Abstract: A locomotion control system is constructed to input the quantity of materials in the real world, such as the quantity of motion state of a robot, external force and external moment, and environmental shapes, measured with sensors or the like. By integrating all calculations for maintaining a balance of the body into a single walking-pattern calculating operation, both a locomotion generating function and an adaptive control function are effectively served, the consistency of dynamic models is ensured, and interference between the dynamic models is eliminated. Calculations for generating a walking pattern of the robot can be performed in an actual apparatus and in real time in a manner in which parameters, such as a boundary condition concerning the quantity of motion state, external force and external moment, and the trajectory of the sole, are settable.

    Abstract: The motion of the movable sections of the robot is taken for a periodic motion so that the attitude of the robot can be stably controlled in a broad sense of the word by regulating the transfer of the movable sections. More specifically, one or more than one phase generators are used for the robot system and one of the plurality of controllers is selected depending on the generated phase. Then, the controller controls the drive of the movable sections according to continuous phase information. Additionally, the actual phase is estimated from the physical system and the frequency and the phase of the phase generator are regulated by using the estimated value, while the physical phase and the phase generator of the robot system are subjected to mutual entrainment so that consequently, it is possible to control the motion of the robot by effectively using the dynamics of the robot.

    Abstract: Featured is a controller for a motor that is ultra-compact, with a power density of at least about 20 watts per cubic cm (W/cm3). The controller utilizes a common ground for power circuitry, which energizes the windings of the motor, and the signal circuitry, which controls this energization responsive to signals from one or more sensors. Also, the ground is held at a stable potential without galvanic isolation. The circuits, their components and connectors are sized and located to minimize their inductance and heat is dissipated by conduction to the controller's exterior such as by a thermally conductive and electrically insulating material (e.g., potable epoxy). The controller uses a single current sensor for plural windings and preferably a single heat sensor within the controller. The body of the controller can also function as the sole plug connector.

  • Patent number: 7496428
    Abstract: A desired gait is generated so as to satisfy a dynamical equilibrium condition concerning the resultant force of gravity and an inertial force applied to a legged mobile robot 1 using a dynamics model which describes a relationship among at least a horizontal translation movement of a body 24 of the robot 1, a posture varying movement in which the posture of a predetermined part, such as the body 24, of the robot 1 is varied while keeping the center of gravity of the robot 1 substantially unchanged and floor reaction forces generated due to the movements and is defined on the assumption that a total floor reaction force generated due to a combined movement of the movements is represented as a linear coupling of the floor reaction forces associated with the movements. The dynamics model represents movements as a movement of a body material particle or the like and a rotational movement of a flywheel.

  • Patent number: 7409265
    Abstract: It is arranged such that displacement sensors (70) are installed at a position in or vicinity of elastic members (382), to generate outputs indicating a displacement of the floor contact end of a foot (22) relative to a second joint (18, 20), and a floor reaction force acting on the foot is calculated based on the outputs of the displacement sensors by using a model describing a relationship between the displacement and stress generated in the elastic members in response to the displacement, thereby enabling to achieve accurate calculation of the floor reaction force and more stable walking of a legged mobile robot (1). Further, a dual sensory system is constituted by combining different types of detectors, thereby enabling to enhance the detection accuracy. Furthermore, since it self-diagnoses whether abnormality or degradation occurs in the displacement sensors etc. and performs temperature compensation without using a temperature sensor, the detection accuracy can be further enhanced.

  • Patent number: 7400939
    Abstract: A motion equation with a boundary condition regarding a future center-of-gravity horizontal trajectory of a robot is solved so that the moment around a horizontal axis at a point within a support polygon is zero when the robot is in contact with a floor or so that horizontal translational force is zero when the robot is not in contact with the floor and so that connection is made to a current horizontal position and speed of the center of gravity. In addition, a motion equation with a boundary condition regarding a future center-of-gravity vertical trajectory of the robot is solved so that vertical translational force acting upon the robot other than gravity is zero when the robot is not in contact with the floor and so that connection is made to a current vertical position and speed of the center of gravity.
