A team of scientists from Cornell University has unveiled an innovative biohybrid robot controlled by mushrooms. This technology combines biological elements with robotic electronics. The team developed 2 versions of the biohybrid robots: one moves using wheels, while the other resembles a starfish and uses limb compression to move. Both respond to light stimuli, which prompts them to change direction. Unlike most biorobots that use animal cells, the researchers used mycelium of oyster mushrooms (Pleurotus eryngii). In their study, published in the journal Science Robotics, the scientists described how its branched networks can interact with the robot's electronics through electrical signals. To do this, oyster mushroom mycelium was grown in 3D printed structures with electrodes. This electrical interface converts the impulses emitted by the mushrooms into digital commands to control the robot's movement. The researchers believe that these biohybrid robots could be useful for detecting chemicals or bacteria in fields. According to the authors of the project, this could have a significant impact on the development of agriculture or industrial sectors.
