A two-arm universal constructor is one along the lines of the original Gemini spaceship, where two independently programmed construction arms sent gliders in pairs on 90-degree paths to collide with each other at the construction site. Construction recipes for two-arm constructors are much more efficient in general, but they require many more circuits and multiple independent data streams, which both tend to increase the complexity of self-constructing circuitry.
