Nissan EPORO Robot Car Collision-free Driving theme from Fish Behavior

Among the growth of technology that has tuned to an extent where robots and embedded system plays prominent role in their respective departments, Nissan announced that it has developed robots that are able to move in a group without colliding into each other. Much like a school of fish, the so-called Eporo can also avoid obstacles standing in their way safely. Nissan claims this is the first time the world sees robots that are able to show group behavior.

The company aims at employing the underlying technology in their future vehicles and not commercialize the robots, the process theme would helpful to avoid collisions by the communication between each vehicle and also that technology could reduce the number of traffic congestions in the future.

Extraordinary "anti-collision" abilities,
Navigating instinctively and intelligently through challenging terrain by detecting and avoiding obstacles - just as future Nissan safety vehicles may have the
capability to do.

In developing EPORO, three rules of fish behavior were applied to its driving control. School of fish swimming:

Generically, fish recognize the surroundings based on lateral-line sense and sense of sight and form schools based on three behavior rules. A laser range finder 4 is used for lateral-line sense, while UWB 5 communications technology is utilized for the sense of sight.

Fish Behavior Rules
AREA 1: Collision Avoidance
Change traveling direction without colliding with other fish.
AREA 2: Traveling Side-by-Side
Travel side-by-side with other fish while keeping a certain distance between each fish (to match the speed).
AREA 3: Approaching
Gain closer proximity to other fish that are at a distance from them.

On a whole it makes us to think how come these fishes judges and perform Collision-free swim (drive).

New Micro battery, power packed for high performance

For a size of a few millimetres, the new micro-batteries are powerful enough to jump start a car battery and then quickly charge the cell phone. Researchers from the University of Illinois have developed the micro batteries which can be used to drive compact electronic devices and new applications for radio communications. The micro batteries are so good that they can even out power the super capacitors. The results were published in ‘Nature Communications’ in the April 16 issue. The micro batteries have energy and power and with the researchers tweaking the structure of the micro batteries a little bit, its use can be for wide range applications. The high performance of the micro battery is based on its 3-dimensional micro-structure. Based on the design of fast charging cathode by Professor Paul Braun’s group, researchers developed the matching anode and integrated it with the fast charging cathode at a micro-scale and made a complete battery with high performance. These batteries cou

Google Health Login Page is Ready!

Google's Marissa Mayer announced that the Google Health will be launched on 2008. The service of the Google Health Login Page is ready. It's only the first intro page is displayed and I didn't get passed to the next page. In the same page y0u can see the information displaying on the Google Health. If you point your mouse on the below link you can visit the Google Health Page With Google Health, you can: * Build online health profiles that belong to you * Download medical records from doctors and pharmacies * Get personalized health guidance and relevant news * Find qualified doctors and connect to time-saving services * Share selected information with family or caregivers This will be a nice development about caring health and this will helps in having some cautious about health.
