Tiny Robots Fly in Swarms

Tiny Robots Fly in Swarms

The hand-sized quadrotor, a small flying robot built by a team at the University of Pennsylvania's General Robotics, Automation, Sensing and Perception (GRASP) Laboratory, can now fly in swarms.

The GRASP Lab research team released no technical details in its latest announcement, which consists only of a very short video. The so-called nano quadrotors are shown performing some pretty amazing swarming behavior and flying in complex formations. The term "nano" is quite a stretch, since their wingspan appears to be about four or five inches. The GRASP Lab's Website says that its researchers are "building autonomous vehicles and robots, developing self-configuring humanoids, and making robot swarms a reality."

The video's voiceover states, "We developed a nano quadrotor capable of agile flight. Multiple vehicles can fly as a formation. We developed a method to transition between formations in 3D. The team can also navigate in environments with obstacles." Up to 20 quadrotors are shown flying in formation through and around various obstacles.

At the end of the video, they fly in a figure eight pattern. Near the end, the video tells us that the quadrotors were developed by KMel Robotics.

Researchers at the GRASP Lab have been working on the quadrotor design since at least 2010, when its first videos were released. In these videos, the most complex thing the quadrotors do is build tower-like cubic structures from modular parts. (You can watch them do that here.)
