  • Patent number: 7698020
    Abstract: Displacements of respective joints corresponding to respective joint elements (J9 and the like) of a rigid link model (S1) representing a two-legged walking mobile body (1) are sequentially grasped. Also at the same time, values, in a body coordinate system (BC), of an acceleration vector of the origin of the body coordinate system (BC) fixed to a waist (6) as a rigid element, a floor reaction force vector acting on each leg (2), and a position vector of the point of application of the floor reaction force vector are sequentially grasped. With the use of the grasped values, joint moments respectively generated in an ankle joint (13), a knee joint (14), and a hip joint (9) of each leg (2) are sequentially estimated based on an inverse dynamics model using the body coordinate system. The estimation accuracy of the joint moments of the leg can be enhanced by reducing arithmetic processing using tilt information of the two-legged walking mobile body relative to the gravity direction as much as possible.

    Abstract: A robot platform includes perceptors, locomotors, and a system controller, which executes instructions for autonomously navigating a robot. The instructions repeat, on each iteration through an event timing loop, the acts of defining an event horizon based on the robot's current velocity, detecting a range to obstacles around the robot, testing for an event horizon intrusion by determining if any range to the obstacles is within the event horizon, and adjusting rotational and translational velocity of the robot accordingly. If the event horizon intrusion occurs, rotational velocity is modified by a proportion of the current rotational velocity reduced by a proportion of the range to the nearest obstacle and translational velocity is modified by a proportion of the range to the nearest obstacle. If no event horizon intrusion occurs, translational velocity is set as a ratio of a speed factor relative to a maximum speed.

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: 7515992
    Abstract: A robot apparatus in which the storage capacity necessary for holding motion data is diminished in representing the emotion by motions exploiting the body resources. In demonstrating component behaviors of the robot apparatus, the basic posture, as the posture at the start time of one or plural movements forming a component behavior, is changed to express the emotion. Specifically, the robot apparatus includes variations for expressing the emotion for the basic posture (basic posture for the emotion). The respective resources are actuated from the basic posture for the emotion and reversion is made again to the basic posture to demonstrate the emotion.

  • Patent number: 7509177
    Abstract: The invention relates to the control of an orienting/positioning system comprising comprising at least a sensor and an actuator for controlling an orienting and/or positioning action adapted to change an input space of the sensor. A first step evaluates pre-action output information of the sensor in order to detect a pre-action position of a manipulating device in the input space of the sensor. A second step decides on a targeted post-action position of the manipulating device in the input space of the sensor. A third step defines a command for the actuator by mapping any deviation of the pre-action position and the targeted post-action position in the input space of the sensor to actuator control coordinates using a predefined mapping function. A fourth step orients/positions the manipulating device according to the defined command in order to carry out the orienting/positioning action. A fifth step detects a real post-action position of the manipulating device in the input space of the sensor.

  • Patent number: 7479751
    Abstract: A method is employed to eliminate undesired velocity reversal in a motion profile. A start speed, a start acceleration, a speed limit, an acceleration limit, a deceleration limit, an acceleration jerk limit, and a deceleration jerk limit are programmed for the motion profile. A critical jerk value needed to avoid velocity reversal associated with the motion profile is calculated. The critical jerk value is compared to the programmed deceleration jerk limit. The larger of the critical jerk value and the programmed deceleration jerk limit is set as a computed maximum deceleration jerk limit for use with the motion profile. In this manner, the computed maximum deceleration jerk limit will never be lower than the critical jerk and undesired velocity reversal is eliminated.
