"Bigdogs" dogs of war

It's an article that I research for french class and I like it to much and is about some war robot dogs. They are some machines that have 4 legs articulated for movement and they can walk over all surfaces, they can carry heavy loads. they are 3 feet long, 2.5 feet tall and weight 240 lbs. control system keep it balanced. and it have sensors for locomotion. runs at 4 mph. climb slopes for 35 degrees, and it can carry 340 lb load. I like this article more than the others in the magazine, because this is a great advance in technology, and it has more of engineering, and thats what I want to study.
I search on internet more about this dogs and I found this video:

article

they say that in a pensilvania university, some engineers found that for airplanes to be faster, they needed to change their wings form, to see more like a bird. They are making many practices, becuase if it's right, it will change the common airplane, and will be better. In the magazine also they talk about cars, that today they are few that have a sensor, for reducing the accidents in the streets, they have a radar, so they know when an obstacle is comming, and also when a curve is comming. The cars with time, will become more little, becuase we are going to need more space for future generations. Another thing they mention, is that there are already prototypes of flying cars, they can fly for a short distance, but they are too expensive. But we are waiting becuase technology is growing really fast, so in little time it can change all what we have think it was.
