As robots go, there are definitely some that are more complex looking than others. Not everything has to look like a Michael Bay creation to be potentially useful as an MIT project recently demonstrated.
Looking at these reconfiguring robo-cubes, created by research scientists at MIT in the face of ongoing naysaying, it strikes me that the human race can’t be far off a huge achievement: building a physical version of Tetris that self assembles. From angular chaos, to robot-enabled order. That and giving future Dalek armies the ability to bound up stairs.
