Robot car which learned full power running found out that drift cornering with good feeling can also be done



Automated driving cars that are being developed by Google and other automobile manufacturers and IT-related companies all over the world are aiming for safe driving using AI (artificial intelligence) technology. On the other hand, the robotic car developed by the research team at Georgia Institute of Technology "AutoRally"Mastering to run through the course of dirt (Saturday) at high speed, and while drifting lightly during cornering.

AutoRally

AutoRally is an experimental vehicle based on a radio controlled car which is 1/5 the size of an actual car, a vehicle of a size of about 1 meter in total length and about 21 kg in weight.


Onboard car is equipped with onboard computer, front camera, GPS sensor etc. It is possible to run by judging by yourself even without doing any external operation.


AutoRally running up the dirt. It is said that the maximum speed on specs can reach 105 km / h.


You can see how AutoRally travels and makes a cornering in the following movie.

AutoRally is able to run while choosing the most efficient line, predicting the route the car will travel in the course to run.


While constantly making 60 judgments per second, always find the best line and run.


As you can see, it seems to have the ability to slide the rear wheels and perform a drift driving with a light counterattack.

Even when driving fails, I will repair myself, as if it were possible to respond like human beings. Like this, even when you are going to be stuck with a cornering failure ......


Restart properly and restart driving.


Even if I'm about to overturn with "oops" ...


Successful avoidance of rollover and recovery completed.


However, sometimes recovery does not go well.


I got stuck outside the course ......


Even getting overturned.


Disturbing posture at the corner exit while keeping high speed ......


Reverse HanLeave "Fishing" as it is ... ...


It also sticks to the outside of the course as it is. It is like AutoRally which sometimes makes the same kind of mistake as a human being, but it may be that it is possible to reproduce driving close to humans.


Detailed specifications are as follows. There seems to be only a large size radio controlled car, and the front wheels seem to be equipped with brakes.


Sensors include an IMU (inertial measurement device) and a GPS sensor that can measure 200 times per second, two front cameras and a tire rotation sensor, etc. CPU has Intel i7 quad core 3.1 GHz, GPU It is equipped with NVIDIA GTX 750ti to enable autonomous operation.


Sometimes it's AutoRally showing a pretty aggressive run. Even in the real world of racing, computer simulation technology has evolved dramatically, but it seems that it will not be long before the day for robot cars to show great driving than human beings will come.
