Our current form—bipedal & prone to toppling, with two limited manipulator arms—always struck me as less functional than it could be. If I were making sentient beings, I would first try something else. I can therefore never understand why robot makers are always trying to copy the humanoid template and create androids. Fortunately there are other robotics experts who are willing to consider more versatile shapes for the next generation of robots. Consider this robot octopus, manufactured by a Greek team.


The robo-octopus can swim using traditional octopus jet propulsion (particularly effective because of the elastic webs between its tentacles). It can also crawl along the ocean bottom with its many arms and utilize its synthetic tentacles to carry or manipulate multiple objects.


So far the robo-octopus is merely an experimental plaything and it has all the awkwardness of some first generation Pre-Cambrian jellyfish, but it is hard not to see immense potential in that adaptable be-tentacled shape. Imagine combining it with a supercomputer and giving it wrap-around artificial eyes. What a magnificent robot that would be!  Indeed, maybe we could utilize such a shape for transhuman cyborgs of the future.  Humans could swim around in three dimensions and be free of all this right-leg/left-leg falling down business!
