Helicopters are versatile machines capable of all manner of maneuvers in the air, but when it comes to takeoffs and landings they are very fussy creatures, preferring flat, level pads, which are scarce in combat and rescue missions. DARPA recently demonstrated a new robotic landing gear system in an unmanned flight near Atlanta, Georgia, that’s designed to overcome these limitations by enabling landings on broken or uneven terrain with a high degree of safety.
