Time would be better spent getting rid of umpires like Ángel Hernández. If you want to install the technology and use it for limited "X" appeals per team per game on the umpire's call, that's fine. But there is no need to take away calling balls and strikes away from umpires.
MLB Umpires are probably correct between 95% and 99% of the time.
Here's what is going to happen with the robo system: It's going to call a pitch which is technically a strike as a strike. This will be the sweeping breaking ball where one-quarter of the ball just crosses the very corner of the FRONT of home plate and then the catcher catches the ball 8 inches off the plate. When the batter hears it called a strike, he will say it's wrong. And perception is reality. To the players, the robo ump will be wrong one to five percent of the time. So, what are we really improving here?
A catcher's dad view. 
Much more of the missed balls/strikes calls are balls called strikes, rather than strikes called balls. Occasionally, you'll hear a pitcher think/say "Where was that?"
