They still don't exist robots ruled with bacteria, but how would they work? What advantages would it have? That is what they try to answer, through a mathematical model, those of the Virginia Tech research center in the United States.
The different genetic expressions of bacteria E. Coli they would be thus detected by the sensors and the miniature fluorescent microscopes of the robot. The E. coli they would turn red or green (with different intensity) depending on what they ate, thanks to a small genetic modification, and robot system would react to those chromatic changes.
This interaction would allow, according to Virginia Tech experts, to better understand the role that bacteria play in the regulation of the human organism or even in our mood swings. This could open the door to a new way of programming robotic functions in imitation of bacteria through synthetic biology.
This approach to robotics could have a lot of innovative applications in the fields of agriculture, health and environmental cleanliness. These fields depend heavily on the relationships between bacteria and their hosts..
The mathematical model also translates the data of the genes of the bacteria, the fluid in which they move and their own movement. Then they transform all this into movement patterns for a small robot with wheels.
