Tiny, Robotic Cars Learn to Drive From Fish Schools

Nissan is looking to schools of fish to learn about how to help people reduce car crashes and traffic jams. The car company developed tiny robots that move in fish-like groups of up to 7 without bumping into each other. Each uses a laser range-finder to measure the distance between obstacles. The data is constantly shared between peers via radio, allowing the group to travel as a "shoal" without bumping into each other. The technique allows the cars to travel side-by-side or quickly switch direction as a group

[BBC News].

The robot is dubbed Eporo, which stands for Episode O (Zero) Robot, meaning zero episodes, or accidents, and zero emissions. This is Nissan's second attempt at designing a crash avoidance system based on animal behavior. Their last attempt was the BR23C robot,

modeled after the anti-collision behavior of bumblebees (check out a video of the bee based bot here).

The Eporo, however,

imitates three rules of fish movement: avoiding crashes, traveling side by side, and keeping close to other members of the school [CNET]

. Nissan plans to unveil the Eporo at the Ceatec conference in Tokyo on October 6. Related Content: 80beats: Robo-Fish Are Ready to Take to the Seas 80beats: To Win the Evolutionary Race, Robots Learn to Deceive 80beats: Scientists Glean Secrets of Flight From Birds, Bats, and Bugs
