  • Patent number: 10691120
    Abstract: This communication system has a transmitter and a receiver for repeatedly transmitting a frame of steering signal having a plurality of channels. The transmitter stores an identification data of a control parameter of a specific operation object in a first empty channel within one frame and stores a characteristic data of the control parameter of the specific operation object in a second empty channel to transmit along with steering data of other channels. Since the identification data and the characteristic data are transmitted at the same time along with the control data, the control parameters can be changed during steering of the operation object. Since the characteristic data and the identification data are transmitted in the same frame as a pair, when at least the one frame is received, the setting of the control parameter can be changed.

  • Publication number: 20200166955
    Abstract: A driving control device for a remote controlled helicopter includes an rpm detection unit that detects an rpm of a main rotor, a gyro sensor that detects angular velocities of control axes including roll, pitch and yaw axes, and a control unit that generates a control signal of a control actuator for controlling movements of the control axes based on the angular velocities detected by the gyro sensor and a steering signal sent from a transmitter. The control unit has information on the gyro sensitivities of the control axes and information on a set rpm of the main rotor which are preset for each of the flight states of the remote controlled helicopter, and corrects the gyro sensitivities based on a difference between the set rpm corresponding to a selected flight state among the flight states and an rpm of the main rotor detected by the rpm detection unit.
