Nissan takes inspiration from nature to develop future mobility technology image

In developing the new technologies that will help shape the future of mobility, Nissan’s engineers have been inspired by the animal kingdom – more precisely by bees and fish.

Toru Futami, engineering director of advanced technology and research, said that studying the behavior of animals moving in groups helps engineers understand how vehicles can interact with each other for a safer and more efficient driving environment.

“In our ongoing quest to develop collision-avoidance systems for the next generation of automobiles, we needed to look no further than to Mother Nature to find the ultimate form of collision-avoidance systems in action, in particular, the behavioral patterns of fish.”

“In current traffic laws, cars are supposed to drive within the lanes and come to a halt at stop signals, but if all cars were autonomous, the need for lanes and even signals could be gone. We talked about fishes earlier, and fish follow these three rules: Don’t go away too far, don’t get too close and don’t hit each other. Fish form schools with these three rules. A school of fish doesn’t have lines to help guide the fishes, but they manage to swim extremely close to each other. So if cars can perform the same type of thing within a group and move accordingly, we should be able to have more cars operate with the same width roads. This would lead to more cars, but with less traffic congestion,” Futami explained.

The research team created the Eporo (EPisode 0 Robot), utilizing Laser Range Finder (LRF) technology—inspired by the bumblebee’s compound eyes that can see more than 300-degrees. Six Eporo units communicate among themselves to monitor each other’s positions to avoid collisions as well as be able to travel side-by-side or in single-file, thus exhibiting the behavior of fish swimming in schools. Futami added that the Eporo could also communicate with one another at intersections, deciding which would go and which would stop, thus eliminating the need for traffic signals.
