An interdisciplinary team of researchers put a culture of the edible mushroom species Pleurotus eryngii (also known as the king oyster mushroom) in control of a pair of vehicles, which can twitch and roll across a flat surface.

By applying algorithms based on the extracellular electrophysiology of P. eryngii mycelia and feeding the output into a microcontroller unit, the researchers used spikes of activity triggered by a stimulus – in this case, UV light – to toggle mechanical responses in two different kinds of mobile device.

    my rule not to eat anything smarter than i am is steering me worryingly close to mushroomless waters

      They're fruits. If you're not eating the colony itself, I think it's okay.

      Sunflowers move towards the sun on their own, this isn't much different from that.

    "This kind of project is not just about controlling a robot," says Cornell bioroboticist Anand Mishra.

    "It is also about creating a true connection with the living system. Because once you hear the signal, you also understand what's going on. Maybe that signal is coming from some kind of stresses. So you're seeing the physical response, because those signals we can't visualize, but the robot is making a visualization."

    Future earth that has nothing but a war thats sigularity ai robots vs mycelial robots. No evidence of humanity left anywhere.

    More science should be mad art experiments.

    Also, they should put the robots in an otherwise sterile controlled environment, with more possible substrates scattered about, and periodically re-pot any new mushrooms into new robots and re-sterilize the environment. You know, give the mushrooms some time to evolve into this niche.

    does it have to look like something out of HR Gigers mind or was that just done out of passion

    oh, passion then. Unsatisfied with just being able to measure stress responses of mushrooms we gave it the ability to move, solely to display stress responses.
