Interesting; but I'm not clear (yet) on what advantages this would have? The cylinders and pistons and the levers look to be quite complicated to make.
I thought it also until i spot a film of someone doing it , making a copy of the 4 stroke Wolff-patent : youtube watch?v=cSOzSKxtWzg
currently i have actually built a second generation , and improving it to run as HCCI as mentioned in a recent Dutch article. this movie is open source, kind of a warm-up.
still have 4 posts to do, to be able to put some links
I'm sure I won't have one in my car in my lifetime....
I'd like to see the corner machine shop bore that out for oversized pistons and rings...
The mass of the "rods" appears.... massive. TWO pivot points are present in addition to the rotating points on the crank so there's likely more internal friction/piston assy than in a conventional layout, plus all that "rod" mass needs to be accelerated and decelerated every cycle. If it runs at all it'll be slooooow.

It's like a more complex version of the Commer TS3, AKA "Commer-knocker". That didn't work out too well and I suspect this won't either.

Boy, there are no easy answers, that's for sure. Toroidal cylnders have got to be 5X harder to make than cylindrical ones, and the same goes for toroidal pistons...
These two in this thread are still oscillating, so even though they are toroidal, they are not rotary. The Garric engine is the only toroidal engine that is also a rotary, as far as I know.
