Under the banner of "Towards The Swarm Of Nano Quadrators", the University of Pennsylvania showcased their new research. They have released a video which shows nano quads flying around in pattern, shapes and with some amazing accuracy. These robots can execute commands like flipping, flying in an eight pattern, return to the last position and getting into formations. These machines come from UPenn's General Robotics, Automation, Sensing, and Perception (GRASP) lab and now the team is working on replacing humans with these quadrators when it comes to search and surveillance.

According to the Huffington Post, the scientific team of the quadrators are currently addressing a few questions that include, "Can large numbers of autonomously functioning vehicles be reliably deployed in the form of a 'swarm' to carry out a prescribed mission and to respond as a group to high-level management commands? Can such a group successfully function in a potentially hostile environment, without a designated leader, with limited communications between its members, and/or with different and potentially dynamically changing "roles" for its members?"

The brilliant formation and flying skills are nothing compared to coding and software used. There are other robots which can do somewhat like the same but what sets these rotors apart from the rest is how brilliantly obedient they are. Especially the figure of eight, it really requires some amazing amount of precision, accuracy and timing.

Implementing these quadrators in real life could be useful in various ways. Apart from military usage, these quadrators can make some crazy toys and could be used for stunts in movies as well.
