Flying low to the ground is a pilot’s nightmare: buildings, trees, and power cables all threaten to put an early end to the flight. But now the first large robotic aircraft able to fly at low levels and weave around such obstacles has been developed by US engineers.Giving uncrewed aerial vehicles (UAVs) this ability could aid military operations in urban areas, or help search-and-rescue efforts after disasters.Most UAVs do not have the capacity to sense and avoid obstacles at all - a significant barrier to their being allowed to fly in civilian airspace.But now engineers at Carnegie Mellon University, Pittsburgh, have modified a commercial civilian UAV helicopter made by Yamaha to be able to see obstacles it encounters.The helicopter’s “eye” is a custom-built 3D laser scanner, which sweeps an oval path ahead of the 3.5-metre long craft. The scanner can detect objects as hard to see as power lines from 150 metres away.
