  • Publication number: 20230056030
    Abstract: An adaptive joystick preferably includes a rotatable cylinder bar, an outer base ring, an inner ring and an industrial joystick base. An adaptive controller receives an output from the adaptive joystick and outputs a control signal to a valve solenoid to control a hydraulic cylinder. Angle, depth and pressure sensors are preferably used to monitor a position of the hydraulic cylinder. The sensor outputs are fed into the adaptive controller. An inward wrist curl of the rotatable cylinder bar combined with a forearm pull rearward of the outer base ring are used to cause a digging motion. An outward wrist curl of the rotatable cylinder bar combined with a forearm push forward of the outer base ring are used to cause a dumping motion. A hand movement to the left is associated with swinging the excavator left. A hand movement to the right is associated to swinging the excavator right.

  • Publication number: 20230056028
    Abstract: A one-handed joystick for excavators allows an operator to make all necessary motions with a single hand and arm for manipulating an excavator tool. The one-handed joystick includes a rotatable cylinder bar, a rotatable ring and an industrial joystick base. The rotatable cylinder bar is grasped with a hand. The industrial base is moved front to back, or right to left. The following are preferable hand/arm motions. A downward hand curl is associated with a bucket digging motion; an upward hand curl is associated with a bucket dump; a forearm forward push is associated with a boom/stick extension; a forearm reward pull is associated with a boom/stick retraction; a left-hand movement is associated with swinging the excavator left; a right-hand movement is associated with swinging the excavator right; a clockwise hand twist is associated with a stick/boom extension; and a counter clockwise hand twist is associated with a stick/boom retraction.

  • Patent number: 11449089
    Abstract: A joystick having increased control functionality preferably includes an industrial joystick base and a rotary upper handle. The rotary upper handle preferably includes an outer base ring, a rotatable ring, a position sensor and a base portion. The outer base ring extends upward from the base portion. The base portion extends from the industrial joystick base. The rotatable ring is rotatably retained in an inner perimeter of the outer base ring. The position sensor is retained in a sensor cavity formed in an inner perimeter of the outer base ring. The rotatable ring preferably includes a ring portion, a rotatable cylinder bar and a compression spring. A center contact and a peripheral contact are retained in an end of the rotatable cylinder bar and make contact with the position sensor. The motion of the rotatable ring and the rotatable cylinder bar are sent to a ring controller for processing.
