No, the word robot used in the title by CNN is a clickbait most media does these days. There won't be any robots standing or sitting on the ground. It's only the use of technology for critical decisions. Like Cricket's third umpire, robots a.k.a. decision review system in MLB can't be challenged. 

I agree. You can also challenge the robot if you disagree, just like with real umpires.

Yeah. It hardly takes a minute. I've seen it but I've been experiencing much similar use of technology in Cricket for 15 years and I've no objection to it.

MLB to test robot umpires as part of challenge system at next Spring training

This challenge system is super quick if you have seen any minor league games (forgot what level they are on) I mean it takes longer to argue balls and strikes then the challenge!
