This was a new word for me, so I had to look it up: It’s an… interesting choice of words to describe the success of a robot.
Of course a robot would perform the job unflappably, it is emotionless by design. I’m pretty sure it would go right ahead and murder the patient unflappably as well. The robot “keeping its cool” is not even a question.

That said, this does sound very impressive, even if I think there’s some pretty crazy risks involved. Hopefully they have more respect for the problem then self-driving car companies.
