       steering_left_pwm=cfg.STEERING_LEFT_PWM,
       steering_right_pwm=cfg.STEERING_RIGHT_PWM,
       throttle_channel=cfg.THROTTLE_CHANNEL,
       throttle_forward_pwm=cfg.THROTTLE_FORWARD_PWM,
       throttle_stop_pwm=cfg.THROTTLE_STOPPED_PWM,
       throttle_reverse_pwm=cfg.THROTTLE_REVERSE_PWM
   )
   
   V.add(sombrero, inputs=['angle', 'throttle'])
