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.
