New school of thought : Cars may one day mimic fish schools to avoid collisions 以魚為師 車商研發防撞技術

Engineers in Japan say they are a step closer to developing technology they hope will cut the risk of car crashes — by mimicking the behavior of fish.

The experts at Nissan Motor have been studying fish and the way they are able to swim in schools and avoid colliding with each other.

The result is a robot that can travel in a group of up to seven, avoiding bumps by sharing information with its peers.

The firm hopes to use the technology in its vehicles in future.

The three-wheeled robot uses a laser range finder, which measures the distance to an obstacle, and radio communications to recreate the behavior of fish, which can change direction and travel side by side without colliding.

Last year Nissan unveiled a similar robot inspired by the bumblebee, which is also highly adept at avoiding collisions but travels solo.

“We, in a motorized world, have a lot to learn from the behavior of a school of fish in terms of each fish’s degree of freedom and safety,” said Toshiyuki Andou, the principal engineer in the project.

By sharing information, the group can travel safely, changing its shape as needed, Andou said.

日本工程師表示,他們朝希望減少車禍風險的目標又邁進了一步──師法魚的行為。

日產汽車的專家研究魚類及牠們成群游水卻不會相撞的方法。

他們的研發出一種機器人,藉由彼此交換訊息來避免相撞,能穿梭於至多七個同伴間。

日產希望未來能將此技術運用在汽車上。

該種三輪機器人利用可探測障礙物距離的雷射測距儀及無線電通訊,重現魚類能夠改變方向又並行不悖的游水行為。

日產去年就推出一款相似的機器人,靈感來自同樣擅於避免碰撞的大黃蜂,但大黃蜂通常是單獨行動。

該計畫主要工程師安藤俊之說:「身處在機動化世界的我們,可以從每一條魚游水的自由度及安全性中學習到很多。」

安藤說,機器人藉著彼此交換訊息,得以依據需要變換隊形安全行進。
