  • Publication number: 20200050937
    Abstract: A learning-type signal separation method performed using a model formulation unit, which performs learning processing based on a training-use signal including a specific component, and a training-use signal not including the specific component, the training-use signals including a common characteristic. The learning-type signal separation method includes: generating learned data by causing the model formulation unit to perform learning processing based on the training-use signal and information indicating whether or not the specific component is included in the training-use signal, to generate a data series signal in which the specific component has been separated and removed from a data series of the training-use signal; acquiring an arbitrary signal including the common characteristic; and generating, based on the acquired arbitrary signal and the generated learned data, a data series signal in which the specific component has been separated and removed from a data series of the arbitrary signal.

    Abstract: An apparatus including a tendon-driven device such as an endoscope comprising a bendable body, a tendon attached to and extending a length of said body, and an actuator that will actuate said tendon based on a control signal from a controller. The controller is configured to send said control signal to said actuator and comprises a forward-kinematic-mapping unit that estimates an angular displacement, wherein the kinematic-mapping unit is configured for: providing a tension value of the tendon to obtain a desired angular displacement wherein the tension has a nonlinear relationship with the desired angular displacement based on information of friction where the tension is greater that would be calculated without including the effect of friction. The friction coefficient may be determined as it changes over time.
