human
[MCU] on the Hulkbuster

The design of most iron suits is pretty simple with regards to controls, you move and so does the armor. But this has a scaling problem--the armor has to have little enough bulk that the anatomy of suit and human roughly lines up, or movement is restricted. In the Hulkbuster armor, placing the human operator's limbs inside their armor counterparts would require separating them from the torso, which I'm told would be somewhat counter to the point of having armor.

**TL;DR: How are operator movements translated into armor movements in the Hulkbuster?**

The point of the Hulkbuster isn't so much to protect Iron Man from the Hulk - his ordinary suit would probably do just as well - but rather to unleash a heckton of heavy ordnance on the sucker in order to get him to sleep for a little while. Thus, the Hulkbuster isn't so much meant to be armour as it is a heavy weapons and punching-things platform, kind of like a Jaeger but really scaled down. Thus, Iron Man operates the Hulkbuster from inside its chest with sensor modules that line up with the actuators in the joints and also punching-things. The Hulkbuster can be used as armour - Banner himself uses it in Infinity War - but it's really meant to be just more firepower and strength.
