See DLX sereis 1 for further details.
The DLX series 03 is the pinnacle of patent autonomous intelligence drones by Detronix. Though they do create a series 04 prototype but it never reaches the development stages.
The DLX3 specialise for more military functions more so than public utility. Outfitted with propulsion thrusters on board arm mounted cannons and new thermal absorption shields designed to transform incoming thermal projectiles (lasers etc) and utilise the energy in their own sub systems essentially overcharging it's capacity for higher efficiency in combat. Another feature is independent up link protocals, they are able disconnect from the monitoring servers in case of emergency shutdowns or capture meaning all the memory data is stored in the command servers. The drone is blank of any information and programs that allow it to run. It's just a shell.
