Displayed this week at CEATEC Japan 2009 by Nissan Motor’s, the new EPORO robot cars provided an example of how near-term future cars will become collision-free by imitating schools of fish by moving in unison while communicating to avoid collision. EPORO works to (1) change direction without colliding; (2) travel side-by-side while keeping safe distances; and (3) gain closer proximity to cars that are at a distance.
