Fictional robots are often remarkably capable, but their real life counterparts frequently have trouble navigating something as simple as a door.
That's changing rapidly. And in a perfect example of just how capable robots really can be, Japanese robotics company Yaskawa Electric Corporation had one of the most skilled swordsmen in the world teach one of their creations how to use a katana.
Isao Machii holds multiple speed and skill world records for his mastery of the martial art of Iaijutsu and his ability with a sword. 
So the company modeled his abilities in 3D to see how perfectly their robot could replicate Machii's efforts.
Each challenge requires incredibly precise movement.
And quick, definitive action.
Just in case that wasn't precise enough for you, watch this.
Yes, this is just one robot programmed to do a specific task. Still... Are we sure this is a good idea?
