  • Publication number: 20180024521
    Abstract: A control device includes: a control portion and a receiving portion, in which the control portion is capable of allowing a robot to perform two or more works selected from first work of performing calibration between a coordinate system of a first imaging portion having an imaging function and a coordinate system of a robot, second work of performing calibration between a coordinate system of a second imaging portion having an imaging function and a coordinate system of the robot, third work of calculating a posture of a virtual standard surface that corresponds to a work surface on which the robot works, fourth work of calculating a distance between the first imaging portion and a standard point of the robot, and fifth work of calculating a distance between an end-effector and the standard point, based on one input command received by the receiving portion.

  • Patent number: 7923972
    Abstract: Exemplary systems and methods for charging a battery with a digital charge reduction loop are described herein. In some embodiments, a system comprises an exemplary digital charge reduction loop which comprises a circuit for determining a charge-current adjustment signal, a counter for generating a digital count value, and a digital-to-analog converter. The circuit for determining a charge-current adjustment signal may base the determination on a source voltage of an input source. The counter may generate a digital count value based on the charge-current adjustment signal. The digital-to-analog converter (DAC) may generate a DAC control signal based on the digital count value of the counter, the DAC control signal being representative of an amount of charge current to be used to charge a battery.
