A complex joystick system master unit embodiment utilizes joystick segments and joystick joints arranged in a particular order with a slave unit arranged in a similar order. A sample master unit with three joystick segments has segment lengths that provide a relative ratio of lengths between themselves. The slave unit articulated arm utilizes controlled segments and articulated arm joints arranged in the same order and having the same relative ratio of lengths between themselves. Articulated arm electronic angle sensors and joystick segment angle sensors produce signal that are applied to a plurality of servos. The servos control movement of the articulated arm so that said respective relative angular articulated arm positions of the articulated arm controlled segments match those of the complex joystick segments.
