MIT Invented a Tool That Allows Driverless Cars To Navigate Rural Roads Without a Map (vice.com)

Posted by BeauHD on from the off-the-radar dept.

An anonymous reader quotes a report from Motherboard: A student at MIT's Computer Science and Artificial Intelligence Lab (CSAIL) is developing new technology, called MapLite, that eliminates the need for maps in self-driving car technology altogether. This could more easily enable a fleet-sharing model that connects carless rural residents and would facilitate intercity trips that run through rural areas. In a paper posted online on May 7 by CSAIL and project partner Toyota, 30-year-old PhD candidate Teddy Ort -- along with co-authors Liam Paull and Daniela Rus -- detail how using LIDAR (a radar-like sensor that uses lasers instead of radio waves to measure distances) and GPS together can enable self-driving cars to navigate on rural roads without having a detailed map to guide them. The team was able to drive down a number of unpaved roads in rural Massachusetts and reliably scan the road for curves and obstacles up to 100 feet ahead, according to the paper.

      Actually it's only about 1/8th of a second of lag as I recall - at least sending signals to the hand, might take slightly longer to the foot. Classic example - have someone rest their hand on a table, extending their fingers past the edge, with thumb and forefinger poised to grab the midpoint of a dollar bill as soon as it's dropped. It's physically impossible to do so as the bill takes ~1/10th of a second to fall half it's length, and thus is safely clear before the signal gets from eye to brain and then to finger tips.

      Of course that's with the subject poised to act in a predetermined fashion the moment a signal is given. Take them by surprise instead and things no doubt slow down a lot.

      I know how to do addition, but if you ask me to tally up a million records it's going to take a while and have errors. So there's plenty reason to make computers do what we do if they do it better. Sure replacing car drivers with self-driving cars might seem a bit pedestrian, like replacing a bunch of people with calculators with a computer. But there's more than a billion of them. Sure you can find lots of things to automate that affect a thousand people. Some that affect a million people. But there's very, very few things that would affect a billion people.

      That goes for jobs too, sure you can divide people into sectors but reality is most do their own fairly unique job, flipping a burger isn't the same as making fries to a robot. But driving a car is something lots and lots of people do for a living, all on the same roads playing by the same rules. If you can pass all the practical and legal hurdles the "smart car" could be as big as the smartphone. Maybe even bigger. Last I heard that was a fairly profitable adventure for Apple...

      Like driving?

      I have a lot of older aunts and uncles who are quickly losing their ability to safely drive themselves to doctors appointments, grocery shopping, etc, and either live in a village so small that there's no taxi around, or they simply can't afford the service. Their (adult) kids' work schedules don't necessarily allow them to take time off to look after their parents. I can certainly see some of these folks come to rely on self-driving cars when they finally become reliable - and they can't come fast enough.

      To handle construction zones, a level 5 vehicle will need advanced information about the construction zone. That means that construction workers are going to have to place beacons. That will become the law sooner or later. A level 4 or lesser vehicle will just expect you to take over.

    This is a step in the right direction. Instead of relying on ultrahigh precision LIDAR maps, they now rely on basic map data your GPS nav unit would have + LIDAR for local information. What this really means is that the level of reliance on LIDAR has dropped significantly. Elon musk called LIDAR a crutch and this, for the most part, ditches that crutch because it's capable of operating in an "unstructured area" (place that hasn't previously been mapped) by using it's "local" sensor (LIDAR in this case) to determine the edges of the road. It's now a matter of implementing a similar sensing system using RADAR and computer vision and your Tesla can autonomously drive you around, disregard and run into pedestrians too! ;)
