Nissan's robot cars mimic fish to avoid crashing

Nissan has developed a mini robotic car that can move autonomously in groups while avoiding crashing into obstacles (including other cars).

The Eporo, Nissan says, is the first robot car designed to move in a group by sharing its position and other information. The aim is to incorporate the technology into passenger cars to reduce accidents and traffic jams.

Although a group of Eporos may look like a gang of cybernetic Jawa, Nissan says the cars' design was inspired by the way fish move in schools.

An evolution of the bumblebee-inspired BR23C robot car unveiled last year, the Eporo uses Nissan's collision avoidance technology to travel in groups. Check out BR23C trying to get away from a Japanese lady in this video.

The automaker studied how large schools of fish can move without colliding. It says Eporo imitates three rules of fish movement: avoiding crashes, traveling side by side, and keeping close to other members of the school.

The robots use laser range finders and ultra-wideband radio to determine distance to obstacles. They also communicate with each other to form the most efficient group formation to maneuver through tight spots.

Eporo stands for "Episode O (Zero) Robot." That zinger of a mouthful means zero episodes, as in zero accidents and zero emissions.

Nissan intends to show off Eporo at the Ceatec trade show next week in Tokyo.

I think I like being in control of my own vehicle, and if all vehicles worked like this you would not be allowed to drive your own vehicle, but it is a good concept.

I do too, but I don't like the person near me in control of their vehicle if they are also talking or texting on a cell phone, trying to put on makeup, shaving, reading a book, watching a movie...

I disagree. I think we would be allowed to drive our own vehicles, with a manual override, but it wouldn't be necessary most of the time.

This would pave the way for young people to drive without licenses. Imagine that people without licenses would be able to drive but without a license they won't be able to get manual override. That would be kick-ass!

It would also be benifical to those who can't get a license due to a disability.

Or that.

Or the elderly, who though otherwise healthy, may have degraded eyesight or reaction time and shouldn't be driving anymore. My father gave up his license (voluntarily) a couple years ago. It makes it difficult for him to take care of some of the minor things in life. A self driving car would be a huge plus for him. I hope they have them working before I get to be his age.

There are events such as DARPA grand challenge which are designed to improve the abilities of autonomous cars. The latest event winner showed the ability to move in a deserted military base at the same time obeying traffic rules. For more on autonomous and military robotic vehicles visit also http://www.roboticmagazine.com/military.php This news is also another development on the subject in the sense that it is seeking to improve the coordination of such vehicles.

Well they look cute and it's a real interesting idea, but then people wouldn't be as careful and as mindful as they should be.

The technology is awesome, but the thought of how much more lazy people will get as a result just makes me shiver.

400,000 deaths on average every year in the US on our highways. Largely due to drivers error, how many times have you had to drive tired? This kind of tech, could save the life of someone you love.

It is more like 40,000.

I could finally drive a car without knowing how to!

What a wonderful improvement this would be in the way that we travel short distances when in close proximity to many others (freeways) and over long distances when we travel with fewer vehicles close-by (interstates and highways). In-town driving (inter and intra neighborhood) could be by manual control, allowing immediate changes in a driver's desired destination. A lot of productivity and/or enjoyment could be gained by being free of the mundane task of driving. I drive a minibus for a living, and I can tell you that I see and enjoy so much more when on occasion I ride it, instead of driving it.

Yeah but I hope Microsoft is not designing the operating systems, or other wise some hacker is going to have fun with his toy cars.

Nice idea an we probably capable of getting these things on the road in the next few years. Unfortunately it will not happen until insurance issues are overcome.

The insurance isn't even an issue.
@ ssco00,
good catch, misplaced zero. Thanks for the correction.
I guess 40,000 dead Americans every year is an acceptable lose, right?
That is almost the total number of deaths for the entire Vietnam conflict.
It's only Americas quiet holocaust, why change the way we get around when you can get low low financing, make your credit better by buying a car, be sexier and more confident while stuck in the traffic driving in from the suburbs. Plus while doing so, you get the confidence of knowing your in own personal metal & plastic self expression mobile and the money you spend on gas is supporting people who want to bring down America. Think about that while your spending nine hours a week alone in your car, or are texting and talking the phone endangering everyone around you? hmm, maybe if this car did come along you could still have your own metal and plastic self expression mobile and text your heart out.
