Arming AI humanoid robots seems much more intimidating in my opinion. Though, that is likely due to my lack of familiarity and experience with robots.

This is a robot known as FEDOR. It is allegedly capable of performing a variety of tasks autonomously, including dual firing pistols, driving a vehicle, using tools, and a range of physical movements.

Of course the mind likes to wander into thoughts about a fictional story called Terminator. Should that story be taken as an indication that we should ban robots that can sometimes be described as "Assault Robots"?

Should we altogether halt the development of robots because they may have the capacity to kill, despite all of the other useful things they may be able to do?

Humans have developed a wide variety of tools throughout history that can be used to kill. There are countless examples of situations that having that ability has been our greatest asset. The human body itself is not the most useful form when it comes to survival. Having the capacity to engineer tools with growing complexity has assured our ability to overcome adversity and facilitate adaptation. Like it or not, this includes tools designed with killing as the sole function. To single out one form of tool over another because of the individual's perceived polarity of the use of that tool would be to impose a limitation of the ability of the human to continue to adapt and evolve.

The problem is never the tool, but the one who misuses it.
