class Robot extends Model {}
$r = Robot::findFirst("id = '1'");
$r->count = array('a','b','c','d');
var_dump($r):
protected '_related' =>

'count' =>
array (size=4)

What's your question?
I want to need property:count, but it access protected
Phalcon models have magic getters and setters, so when you call
$Robot->count = ['a','b','c','d'];You're actually calling
$Robot->__set('count',['a','b','c','d']);Even though it's protected, you can still set it.
Read through the documentation about related models - it might give you some insight.
