Fungus-Controlled Robots Harness the Unique Power of Nature

Fungus-controlled robots are an innovative fusion of biology and technology. By leveraging the unique properties of fungi, these robots utilize natural processes for improved functionality and sustainability. This approach not only enhances the robots' adaptability and responsiveness but also promotes eco-friendly advancements in robotics, showcasing how nature’s power can inspire and drive technological progress.

Cornell University researchers have introduced a novel component for robots: fungal mycelia, sourced from the forest floor. By utilizing the electrical signals of mycelia, they have developed "biohybrid" robots that may respond to environmental changes more effectively than purely synthetic robots.

The findings, published in Science Robotics and led by Anand Mishra and Rob Shepherd, highlight a new approach to enhancing robot autonomy using fungi. Shepherd notes that this research is a precursor to using fungal systems for environmental sensing and control in robotics. Future applications could include detecting soil chemistry to optimize agricultural practices and mitigate environmental impacts.

Mycelia, the underground network of mushrooms, can sense and respond to various chemical and biological signals. Mishra emphasizes that integrating these living systems into robots enables them to adapt to unexpected inputs.

The researchers created two biohybrid robots—a spider-shaped soft robot and a wheeled bot—demonstrating their ability to respond to environmental stimuli. Experiments showed the robots altering their movements in response to mycelia's signals and external ultraviolet light, while also allowing for control beyond natural mycelia signals.

This research was supported by the NSF CROPPS Science and Technology Center, the USDA National Institute of Food and Agriculture, and the NSF Signal in Soil program.
