Wow, I'm really surprised to see so many people against this practice!

My team only ever goes to one regional, so I guess it's different at others, but I've never heard the call of "ROBOT!" as a "Get out of my way or I'm going to run you over!" sort of thing (Which is certainly rude and arrogant), I've always heard is as a warning, like "FORE" in golf.

We always have people out in front of the cart to clear a path, and don't go ramming the cart through if there are people in the way, but we still yell "ROBOT!" as a warning to people nearby to watch themselves. We also often yell "Watch out! Robot coming through!"

Robots often may have protruding arms or elements that (while inside the frame perimeter of course) may still hit people who thought they were out of the way. If you direct your warnings only to the people in front of you, who are in your way, people on the sides of you may not be looking out for you.

So alerting people in the area, not just the people directly in front of you is necessary in my opinion.
