If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …
Here's the problem, neatly summarized by the researchers: In order to be widely accepted as a new mean of transportation, PAVs [personal aerial vehicles] automation capabilities should not only ensure safety but also tackle the problem of the passengers comfort. The EPFL researchers modified a strategy called Optimal Reciprocal Collision Avoidance, or ORCA. ORCA is a "reactive decentralized collision avoidance strategy" that can make sure that multiple robots can avoid running into each other in 3D space. The idea is using "fully or partially autonomous Personal Aerial Vehicles (PAVs) for travelling between homes and working places, and for flying at low altitude in urban environments."
The FCC filings referenced in the IEEE Spectrum story are not part of our autonomous vehicle development program. This is the first concrete indication of the scale and intended deployment date of GM and Lyft's autonomous on-demand network since GM announced a US 500 million investment in Lyft in January. In late July, however, engineers at General Motors filed applications for thousands of millimeter range radar systems. The 76-GHz radars represent "a new hardware generation", according to a written request to the FCC for confidentiality by Jeffrey Clark, a GM engineer in charge of long range radars.
