My host explained to me, "Well, the robot is trying to get from point A to point B, and you were an obstacle in his way, so he had to replan his path, figure out where to go, and then get there some other way," which was actually not a very efficient thing to do.
Meu anfitrião me explicou: "O robô está tentando ir do ponto A ao B. Como você estava no caminho, ele teve que replanejá-lo, descobrir para onde ir, e chegar lá de outra maneira", o que não foi muito eficiente.
