The robot tried to cross the street against a Don't Walk signal it should have obeyed. That behavior is a defect, which the manufacturer should be responsible for. Whether the robot "fled the scene" is only an issue if the robot is smart enough to recognize that it caused a problem, and left to avoid the consequences - which I srsly doubt. I mean if the robot were a live dog we wouldn't expect it to understand the situation enough to flee, we would assume it just ran off because it's a dog.
