Actuator quality and design influence how accurately a robot can be modeled, including in simulation.

“like the quality and how you design actually really matters for how well you can model the robot right actually there's what drives the robot to build a model your robot very well in simulation or to do any kind of modeling you need to select actually it's very good but you know can't actually be easily modelable so that's what we care about eventually so we're going to own that same thing with you know the robot's proportion you know this robot's proportion is like”
