Scientists at Carnegie Mellon University in the United States devised an Unmanned Aerial Vehicle capable of flying at low altitudes, navigating in tight spaces and avoiding even the most subtle obstacles. This mini-helicopter uses a 3D map to mark the major obstacles such as buildings and bridges.
According to the research team, a 3D laser equipment detects less obvious barriers such as high voltage lines to a radius of 300 meters. Read the article online from CienciaHoje.
