So I built this small sailing robot with the rudder at the front, and I was trying to pull something very long and heavy, so that's a four-meter-long object just to pull, and I was surprised with just a 14-centimeter rudder, I could control four meters of absorbent.
Então, construí este pequeno robô à vela com o leme à frente, e tentei puxar uma coisa  muito longa e pesada, um objeto com 4 m de comprimento. Fiquei surpreendido com o facto de,  com um leme de apenas 14 cm, conseguir controlar 4 m de absorvente.
