When the Defense Advanced Research Projects Agency's (DARPA) Grand Challenge autonomous vehicle race debuted in 2004, the results bordered on comedy. None of the vehicles drove more than 7.4 miles. Some ran in dizzy circles. Others stalled atop rocks. A robotic motorcycle journeyed all of two feet before toppling over. A 10-ton commercial truck lumbered forward a few yards and stopped like a confused buffalo, overwhelmed by the multitude of sensor signals zipping past its small brain.
Their technical struggles didn't last long. Nineteen months later, five vehicles finished the 132-mile second Grand Challenge. In 2007, six more completed DARPA's 60-mile Urban Grand Challenge.
Today the work continues. Google's automated cars have logged more than 140,000 miles. General Motors has predicted that self-driving vehicles will be ready by the end of this decade.

Stanford University's "Stanley" won the 2005 Grand Challenge by finishing in six hours, 53 minutes. The Volkswagen Touareg R5 combined six laser range finders with a color camera, radar system, GPS system, and inertial navigation system.

great idea to have self-driven cars but as they say, it could have disadvantages... not being safe enough. this volkswagen r5 has enhanced high tech car parts system like radar gps and inertial system. wish I could rebuild on my vw too... I do search car parts in jcwhitney site...this is where I get cheap car interior accessories
There are some options that I think are a good idea. Adaptive cruise control that maintains a 'safe' distamce from the car ahead, and then resumes speed. But I don't like the function that the car applies the brakes if a collision is imminent. Supposedly the braking will be harsh so that the driver that is texting rather than driving will be unnerved, and not rely on this feature. I don't think I would be comfortable letting the car have control. However, this might be perfect for the driver that would rather text or read a book.
One question on the whole topic: Would you be willing to sign your name to the certicicate stating that the system was "safe enough", in todays litigous climate? I don't think that I would be willing to do that. Yes, there would be honour and fame, but also herds of hungry lawyers. Not within a few hours.
Wow – we already have Skype (so glad there is a "no video" option - I think Jane would have preferred that for those early morning calls) and now yet another futuristic aspect of The Jetsons working towards reality. Now if I could only get a household robot like Rosey, my German Shepherd could learn to speak like Astro and we could all go to a three hour/three day work week like George – now that would be progress!
GM says they will be ready by the end of the decade. I can believe it. There are already mining trucks, ag tractors and other equipment that operate autonomously. Highway speeds with other drivers are a different environment since there is much more variability. these vehicles need to be capable of reacting to random human behaviour, just like we are when at the wheel.
We already have cars on the road, and every time one of these vehicles encounters a situation it isn't programmed for, we can add that to the abilities of the control system. The testing required to deploy these vehicles in production will be in the tens of millions of miles I would guess. A daunting task, but acheivable.
In the early days, there may be vehicles with limited situational capability. Lets say we have a vehicle that can handle highway traffic, but will require the driver to take over in any sort of urban environment with stoplights and such. This capability still has value without being absolutely autonomous.
I agree it is definitely a fun challenge, but I do not know how much confidence I would have in a vehicle driving itself. Cars are already on the market that park themselves, but i am not sure if they will be able to market a car that drives itself by the end of this decade.
I agree with Beth. Although this looks to be a lot of engineering fun and challenge, I think it's going to be a long time before this becomes a (safe and sane) reality.
I have spent a few hundred hours at the testing end of automotive production lines, as well as watching the electrical portions of the vehicles being built. My experience says that no way would the quality be high enough for a life-critical system. We could have driver warning systems that could enhance safety, but production quality would just not be adequate for a road-speed autopilot.
Besides that, the programs would probably be written by some of the same individuals that write the current vehicle system code. That means that the autonomous vehicle would not think at all in the manner that I think, and so it would undoubtedly be unable to handle any exceptions to what it expected. So leave the computers to the engine controls and the navigation screens, where the harm that they can do is much less.
That is right, I won't be able too be fully confident in letting my car drive on itself. Though the texting while driving is funny yet dangerous, that's the one causes major fatal accidents on the road. Yeah, I agree that General Motors is not yet on the verge of technological advancement to lead this kind of automobile innovation.
Tesla Motors plans to roll out a “compelling, affordable electric car” that will sell for about half the price of its high-profile Model S by the end of 2016, company chairman Elon Musk said last week.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
