After frustratedly fixing an unsolvable Rubik's cube over Christmas break (my dad thought it'd be funny to "solve" it by peeling off the labels and putting them back on, but got tired halfway through and left it in an unsolvable configuration), I'd love to see what their robot does if you give it an unsolvable cube.

It would most likely not do anything at all. As the Rubik's solving algorithm should return null (if not stuck in an infinite loop).
