  • Patent number: 11686066
    Abstract: A joystick assembly for a working machine having a working arm includes a controller configured to control a plurality of machine functions, a first electronic joystick in communication with the controller, and actuators in communication with the controller. Each actuator is configured to actuate a function associated with the working arm. The first electronic joystick comprises four axes of movement, and the first electronic joystick is configured to transmit electronic signals to the controller in response to being displaced along an axis from a neutral position. The controller is configured to receive the electronic signals from the first electronic joystick, and to transmit an electrical signal to one or more actuators to actuate the actuators. The joystick assembly is configured such that the controller actuates a different actuator for controlling a different function associated with the working arm, dependent upon the axis of displacement of the first electronic joystick.
