  • Patent number: 9021916
    Abstract: A robotic arm includes a driving unit, a first arm assembly connected to the driving unit, and a second arm assembly. The first arm includes two balls. The second arm assembly includes two arms and two intermediate members. Each intermediate member is secured to an end of one of the two arms. Each intermediate member defines a receiving recess. Each receiving recess has a spherical inner circumferential surface. Each ball is partially received in one of the two receiving recesses and abuts against the spherical inner circumferential surface. The two arms and the two intermediate members are capable of rotating about the balls. The driving unit drives the balls to move. The balls force the arms to move in a direction as a moving orientation of the balls, at the same time the arms rotating about the balls.

  • Publication number: 20150120041
    Abstract: Devices and methods for providing power to tools when the tools are not attached to a robotic device. The power source may be an energy storage device that is attached to a tool frame of a tool cluster. The power provides for the tools to be maintained in a ready state which expedites and/or eliminates the initiation process when the tools and the tool cluster are subsequently reattached to the robotic device. This reduces the time necessary for the tools to be used in the assembly process thereby increasing the efficiency of the tooling system.

    Abstract: A first driving signal is supplied to a first electrode of a vibrating body. A second driving signal is supplied to a second electrode of the vibrating body. A common driving signal is supplied to a common electrode of the vibrating body. A phase of the first driving signal is set changeable with respect to a phase of the common driving signal. A phase of the second driving signal is set changeable with respect to the phase of the common driving signal. Then, it is possible to switch a driving direction of a piezoelectric motor according to which phase of the first driving signal or the second driving signal is varied from the phase of the common driving signal. If the phase is simply changed, a switch is unnecessary. It is possible to reduce a driving circuit in size.

  • Publication number: 20150107395
    Abstract: Systems and methods relating to a clutch system for use in controllably transmitting torque from an input shaft to an output shaft. The clutch system has a torque transmission fluid that has a viscosity that changes based on the strength of an electromagnetic field passing through the fluid. A number of sensors are placed at different radial locations on the torque transmission disks to detect the strength of the electromagnetic field. Based on the strength of the electromagnetic field, the amount of torque being transmitted from the input shaft to the output shaft can be adjusted. Also disclosed is a distributed actuation architecture that uses this clutch system. The distributed actuation architecture allows for the use of a single drive motor in conjunction with multiple instances of the clutch system to actuate a mechanical linkage, such as a robotic arm.

Preferably, the two movable parts are guided through one and the same guideway in order to ensure that these two movable parts rotate very precisely about the same geometrical axis.

  • Patent number: 8702578
    Abstract: A positioning device for positioning a load is provided. The positioning device includes a motor, a measuring device, and an evaluation device. The measuring device is associated with the motor, and is operable to ascertain measurement data that characterizes the motor current consumption by the motor in the positioning of the load. The evaluation device evaluates the measurement data that have been ascertained by the measuring device, so that in that way the loading of the positioning device by the load can be ascertained.

    Abstract: Provided is an actuator device used in a plurality of sites of a multi-shaft driving mechanism such as a multi-shaft manipulator, a robot arm, a leg structure and a snake-shaped robot. A torque sensor 14 is connected to a bearing 17 such as a cross roller bearing through a mount part. As illustrated, the torque sensor 14 is driven by an outer ring relative to a stationary part case 19 of an actuator device 10. An attachment surface of an output shaft frame 20 is arranged in a position offset from the bearing 17 on a side of the stationary part case 19. An entire length of the actuator device 10 in an output shaft direction does not change also after the output shaft frame 20 is attached and an occupied space does not increase.
