Motor#

Inicializando la clase Motor#

Un objeto EXP Motor se crea utilizando el siguiente constructor:

Motor(port, gears, reverse)

Este constructor toma tres parámetros como máximo.

Parámetro

Descripción

port

gears

Optional. Sets the gear setting installed in the Motor, the default is GearSetting.RATIO_18_1.
