Old animatronic headcanon.
I think that the DCA such as the Moon, RUIN Moon, isn't as flexible as he used to be. And would be able to jump high/quickly in accuracy that well. That implies to any animatronic. But talking about the attendants, I generalise their abilities with age, and their warranty. So, their warranty and their age. Their physical age, isn't exactly the same as a human.
I generalize it since they are sentient. I theorise it as they would feel that way mentally. And physically goes by warranty. That over time, where a machine has been used for many years it will eventually start to break down. They generally get called 'old'. These old animatronics lost some of their mobility.
Some of them, than the ones who are severely damaged. The gears that turns the attendants head, had gotten rusty that they wouldn't be able to turn it all the way. Moon's ability to twist, and turn his torso, wouldn't function properly. The cage to support his torso, is broken.
Roxanne, and how she moves about. She can still run, and jump. Surprisingly, but I don't think she would be able to climb properly for example, because her joints are badly damaged.
And her voice box, sounds like it's wearing out a bit. And Monty, when he tried to open those metal doors, using his strength, he couldn't anymore. He's practically disabled, same with Chica. So, I round it around to how ever long they last in warranty, and their age.
