(Phys.org) —Lockheed Martin has announced that it intends to build a new kind of extraction and payload delivery craft that can be flown remotely or at times autonomously. The craft is to resemble a helicopter, but will ...
The quadcopter, which was developed at TU Vienna, can negotiate its way through a room completely on its own. It does not need any human interference, and in contrast to other models, it is not assisted by any external computer. ...
