when humans makes mistake on balls and strikes no one or thing is allowed to correct it.
Players like consistency. They learn what the umpires do from ump to ump. With robots they don’t have to adjust from game to game, more consistency. You’ll never get consistency from one ump to another on balls and strikes.,
In the future two humans on the field non-players an ump to check on the robots and a maintenance person to keep them operating.
If 100% every pitch that touches the zone by a hair is called a strike, I think hitters will have problems for a while until they make the adjustment. Same with high strikes that aren’t called now. The zone is going to get bigger, but as you say it will be the same zone every day from then on.
