MIT and Ford have created a robot-carriers, which are guided without the use of GPS
Source:who don't need GPS — this is something new
In recent years, more and more companies rely on the use of robotic couriers. In order to be able to deliver the parcel to the recipient, they, of course, need to navigate. The solution is simple — use GPS coordinates. In most cases this requires you to first display location to the robot knew where to go. But this causes problems with data security and privacy, because the signal can be intercepted. Is there a way to force the robots to navigate the terrain as something else? Engineers from MIT and Motor Company found the opportunity.
How to find the location without using GPS
Experts from mit have developed a technology that allows robots to navigate around «tips», focusing on the ground and not resorting to communication with GPS satellites.
In fact this system works as well as our memory. When we go for some location where you already were, but remember it only some common features, we focused on what we remembered from the last visit best and thus find the way. For robots tips can be described in General terms such as «front door» or «garage».
The Robot can be trained in the knowledge that, for example, an offshoot of the pavement leads to the path that will probably lead to the front door. — said Michael Everett, graduate student, Department of mechanical engineering . Even if the robot delivers a package to the area in which he was never previously added to the navigation system of hints will help him to navigate. In addition, some areas may be similar to those he had already seen. As in the case of the already mentioned track. These patterns robot remembers that still allows him to better navigate in the city.
The New approach uses already existing algorithms that evaluate and analyze the incoming information that comes through the cameras. As a result, everything that the robot sees, is broken down into semantic clues, such as «sidewalk», «ladder», «front door» and so on. Also to the objects distance is computed, and the algorithm has a system of character recognition. For example, a house number or street name. The result is that if the robot, say, to announce that he wants the number 9 at the end of the street, and the parcel should be left near the stairs, he will calculate how faster to reach the goal. And in order to read a lot of interesting news, anything do not need to count. It is sufficient only
The Researchers used the above algorithms to build maps, and allowed the robot to make decisions and to determine the most efficient path to the destination. As a result, the car delivered the cargo without the use of GPS directly to your destination. In this work the algorithm is quite accurate and the speed of delivery is slightly inferior to conventional robotic couriers. The algorithm can naturally be used not only for delivery but also for, for example, the creation of reconnaissance drones, which will work in environments with poor GPS signal.
