20120309571 | CLUTCH SHAFT, ACTUATOR, CAMSHAFT ADJUSTMENT TRANSMISSION AND CAMSHAFT CONTROLLER - A clutch shaft for a camshaft controller having at each of two ends ( | 12-06-2012 |
20140290607 | CAMSHAFT ADJUSTING MEANS - A camshaft adjusting means for an internal combustion engine includes an adjusting mechanism which is configured as a three-shaft gear mechanism having a drive side into which the drive moment for the camshaft is introduced, an output side which is connected fixedly to the camshaft so as to rotate with it, and an adjusting shaft which is coupled to a drive motor and via which a moment which brings about the relative rotation of the drive side with respect to the output side is introduced into the adjusting mechanism. The adjusting mechanism having one bearing point on each of its drive side and its output side and being mounted via the bearing points with respect to the component which supports the camshaft, in particular the cylinder head of the internal combustion engine. The adjusting shaft is guided into the adjusting mechanism through one of the bearing points. | 10-02-2014 |
20150152751 | CAMSHAFT ADJUSTER - A camshaft adjuster for an internal combustion engine is described, composed of an adjusting gear designed as a triple-shaft gear, with a drive wheel which is driven from the internal combustion engine and via which the drive torque for the camshaft is introduced, of a gear output coupled fixedly in terms of rotation to the camshaft, and of a gear input wheel which is coupled to a drive motor and via which the adjusting torque causing the relative rotation between the drive wheel and gear output is introduced into the adjusting gear, there being provided a failsafe mechanism which causes blocking of the adjusting gear and which, in the event of the absence of an adjusting torque to be introduced via the gear input wheel, acts upon a gear element located between the drive wheel and gear output. | 06-04-2015 |

20130184860 | METHODS AND COMPUTER-PROGRAM PRODUCTS FOR EVALUATING GRASP PATTERNS, AND ROBOTS INCORPORATING THE SAME - Methods and computer-program products for evaluating grasp patterns for use by a robot are disclosed. In one embodiment, a method of evaluating grasp patterns includes selecting an individual grasp pattern from a grasp pattern set, establishing a thumb-up vector, and simulating the motion of the manipulator and the end effector according to the selected individual grasp pattern, wherein each individual grasp pattern of the grasp pattern set corresponds to motion for manipulating a target object. The method further includes evaluating a direction of the thumb-up vector during at least a portion of the simulated motion of the manipulator and the end effector, and excluding the selected individual grasp pattern from use by the robot if the direction of the thumb-up vector during the simulated motion is outside of one or more predetermined thresholds. Robots utilizing the methods and computer-program products for evaluating grasp patterns are also disclosed. | 07-18-2013 |
20130184866 | ROBOTS, COMPUTER PROGRAM PRODUCTS, AND METHODS FOR TRAJECTORY PLAN OPTIMIZATION - Robots, computer program products, and methods for trajectory plan optimization are disclosed. In one embodiment, a method of controlling a robot having a first manipulator and a second manipulator includes receiving a trajectory plan including a plurality of sequential motion segments. The method further includes determining a moveable motion segment, and shifting the moveable motion segment and motion segments subsequent to the moveable motion segment backward in time to a shifted time such that one or more unshifted segments of the trajectory plan occur at a same time as one or more shifted segment segments. The method may further include controlling the robot according to the optimized trajectory plan such that one or more components of the first manipulator are moved concurrently with one or more components of the second manipulator. | 07-18-2013 |
20130184870 | METHODS AND COMPUTER-PROGRAM PRODUCTS FOR GENERATING GRASP PATTERNS FOR USE BY A ROBOT - Methods and computer program products for generating robot grasp patterns are disclosed. In one embodiment, a method for generating robot grasp patterns includes generating a plurality of approach rays associated with a target object. Each approach ray of the plurality of approach rays extends perpendicularly from a surface of the target object. The method further includes generating at least one grasp pattern for each approach ray to generate a grasp pattern set of the target object, calculating a grasp quality score for each individual grasp pattern of the grasp pattern set, and comparing the grasp quality score of each individual grasp pattern with a grasp quality threshold. The method further includes selecting individual grasp patterns of the grasp pattern set having a grasp quality score that is greater than the grasp quality threshold, and providing the selected individual grasp patterns to the robot for on-line manipulation of the target object. | 07-18-2013 |
