Robotic Helicopter Test Flights Succeed

Members of the Berkeley Aerial Robot (BEAR) program have successfully conducted a series of field tests with 130-pound helicopters that not only fly autonomously -- with no human control -- but that also react to avoid obstacles in their flight path.

"Our BEAR group is the first to successfully develop a system where autonomous helicopters can detect obstacles, stationary or moving, and recompute their course in real-time to reach the original target destination," said David Hyunchul Shim, a research engineer on the project, which is based at the University of California, Berkeley.

The researchers say they are inching towards a future of robocopters that could maneuver through forests or city streets.

The development of reliable systems that can handle obstacle-avoidance tasks is still several years away, they say, but the computational foundations for such unmanned aerial vehicles (UAVs) have been laid.
