I see it as a safety hazard more than a safety practice. Here's why.

The problem I see is that it's being yelled so often, and so many times without purpose, that two things are happening:

1. People hear it so often they are tuning it out. It has less meaning now. It's like the boy who cried wolf.
2. Teams are gaining a false sense of entitlement that just because they yell "ROBOT!", other people will immediately move out of their way, and they proceed forward quickly whether the path is clear or not.
