Mushroom learns to crawl after being given robot body

Researchers from Cornell University and the University of Florence have developed a biohybrid robot that incorporates a living mushroom, specifically a king trumpet mushroom, to control its movements. This innovative robot utilizes electrical signals from the mushroom to navigate and respond to environmental stimuli, such as light and chemical signals. The project aims to explore how living systems can enhance robotic capabilities, particularly in unpredictable environments. The robot's movements are demonstrated through various mechanisms, including pumping robotic legs and wheeled systems. The integration of mycelium into the robot's electronics allows it to sense and react to its surroundings, potentially leading to applications in agriculture, such as monitoring soil chemistry and optimizing fertilizer use. This research, published in the journal Science Robotics, represents a significant advancement in biohybrid robotics, building on previous experiments that have included living organisms in robotic systems. The use of mushrooms is particularly promising due to their resilience in harsh conditions, suggesting a new frontier in the development of adaptive robots.

As with any "New York Times Journal of Medicine"-type article, the author of the article didn't understand/chose to inflate the actual research - what they did was create a system that captures the fungus's electrical activity and used those pulses to arbitrarily assign movement rules to the robot. There's no suggesting of the fungus controlling the robot - merely a showcase that we have a system to capture the electrical activity of a mushroom. For all intents and purposes we have a robot with a motor instead of any other indicator - could've been a monitor showing a graph.

Better title would “random input enables robot to wiggle; mushroom used as random generator.”

A book released earlier this year (1) asking about whether humanity is guaranteed to avoid losing the war against fungal pathogens. It turns out that all kinds of fungus generally get more aggressive in hotter climates.

So, this research that their adaptability exceeds slime molds isn't reassuring.

However odd it may seem, fungi are evolutionary closer to animals than to plants.

Coincidently I happened to listen to a bbc radio programme on mushrooms which talked about cordyceps and how it infects ants. The new (to me) research was that the fungus doesn't really infect the brain, more the rest of the body and its muscles. Cordyceps more or less puppeteers the ants body to get it to do what it wants in very precise ways, like making the ant climb to a suitable height and then bite into a particular part of the plant's leaf. All of this from a fungus.

I'm not surprised. Because I like to try out many things in order to gain firsthand perspectives, I tried veganism for a year back in 2003. It was the first time I grilled a portobello mushroom. My system was so completely cleared out of any animal products after many months (including honey) that I was absolutely shocked when I bit into its meaty flesh and was overwhelmed with a sentient connection that went beyond a simple similarity in texture, as it was very obvious to be animal in nature. As I was working at the San Diego Natural History museum at the time, I consulted with the librarian and found that mushrooms do indeed carry a combination of both plant and animal DNA.

I'll show you exactly where this folly leads.

Putting fungus in charge of a robot body leads directly to the creation of the Daleks and then the only way to fix that is to get Doctor Who to destroy the lab growing the mushrooms, as shown here:

Humanity is making a terrible mistake with the "mushroom controls robot" thing, it will not end well - likely with us all cringing in the smoking ruins of civilisation whilst mushroom Daleks search for the survivors amongst the rubble.

Almost certainly.

Learns to crawl isn't accurate but it raises interesting questions about sentience. A better title would be “humans learn to build robot that uses mycellium's bio-chemical reactions to stimuli to pilot a robot”…Kinda long though and not really eye catching ;)

I mean, “learns”? They took an existing biochemical/electrical activity pattern and wired it up to trigger servo motors. The mushroom did not learn anything.

Step 2, take decapitated cadavers and replace head with mushroom. If it turns into half life, we win!
