Last we saw Nissan's crash-avoiding BR23C robot "car," it was rolling along all by its lonesone, taking cues from the humble bumblebee in order to survive in the wilds of CEATEC Japan. Well, it's almost time for CEATEC yet again, and it looks like Nissan has seen fit to give our robot buddy a new bag of tricks, and a proper name: Eporo. Perhaps the biggest news, however, is that it now models itself on fish, which not only gives it greater peripheral vision (courtesy of a pair of laser range finders) to avoid obstacles, but lets it travel in packs similar to a school of fish. The idea there being that these could one day carry passengers and stick close together to reduce congestion on city streets and, in turn, cut down on the number of accidents.
