Sheet metal chassis like look HUGE, but in reality are a lot of empty space. I've really appreciated the look of the 217 / 148 / 1114 robots the last couple of years - they simply look physically imposing because of the lack of open space: they look massive.

One question though on this type of constructive. I imagine one of the trickiest parts of making a sheet-metal frame of this sort is doing the force modeling to understand where you can and cannot remove material.

How are you going about that?
