DX-4 Technical Drones consist of an advanced processor unit, which individually has only a basic intelligence (approximately equal to that of a small animal such as a pterasquirrel), and moves about by way of a compact anti-gravitic generator and a much modified variant of a Tau Jetpack. This allows the DX-4 to hover over the ground and skim over most obstacles. As they hover over landscapes, rotating back and forth, their sensor vane constantly transmits vital information about their surroundings. DX-4 Drones have also been known to communicate at times with each other through a form of audible machine chatter and a flashing of optic signals.
