The robot was absolutely free to go around her, I truly don't see how what she did was illegal. The next time my kids are out doing sidewalk chalk and the mail carrier walks by, should the kids be arrested for obstructing mail delivery?
If your kids are making a point of getting out their sidewalk chalk to block the way of the mail carrier every time they see one, because they have a political grievance against the post office and want to do everything in their power to interfere with mail delivery, then yes they should be arrested for this. This is quite possibly already a federal crime, in fact.
