Worker Robot and Heli Droid

*I'm focusing on tech, futuristic themes and my Sci Fi world, there are more robots to come.
These represent a juxt between harmless civilian robot and armed hovering weapon system. One helps with dangerous and high demand labor jobs, construction and such. The other is a security drone helicopter.
Robots, science wonders and computerized networks dominate my biological tech future verse.
In Core City, robots are semi-common and often owned by a republic government. It's a more ideal future world in current times, if things were different maybe a robotic world of progress would be here by now.
But humanity also devotes a lot of money and time to the science of war...
