Abstract: "Lidar, a technology at the heart of autonomous driving and robotic mobility, performs 3D imaging of a complex scene by measuring the time of flight of returning light p... » read more

Confusion Grows Over Sensor Fusion In Autos


A key strategy for fully autonomous vehicles is the ability to fuse together inputs from multiple sensors, which is essential for making safe and secure decisions, but it's turning out to be much harder than first imagined. There are multiple problems that need to be solved, including how to partition, prioritize, and ultimately combine different types of data, and how to architect the proce... » read more

How Many Sensors For Autonomous Driving?


With the cost of sensors ranging from $15 to $1,000, carmakers are beginning to question how many sensors are needed for vehicles to be fully autonomous at least part of the time. Those sensors are used to collect data about the surrounding environment, and they include image, lidar, radar, ultrasonic, and thermal sensors. One type of sensor is not sufficient, because each has its limitation... » read more

Designing Crash-Proof Autonomous Vehicles


Autonomous vehicles keep crashing into things, even though ADAS technology promises to make driving safer because machines can think and react faster than human drivers. Humans rely on seeing and hearing to assess driving conditions. When drivers detect objects in front of the vehicle, the automatic reaction is to slam on the brakes or swerve to avoid them. Quite often drivers cannot react q... » read more

Research Bits: Feb. 14


Defining Kagome superconductors An international team of scientists and researchers from the Brown University lab are now able to describe the structure of the superconductor Kagome metals. The team used nuclear magnetic resonance (NMR) imaging and a quantum modeling theory to describe the microscopic structure as the metal changed states into a charge density wave (CDW) state at 103°Kelvin (... » read more

Synergies And Limitations Between Road Infrastructure And Automated Driving


This new technical paper titled "Road Infrastructure Challenges Faced by Automated Driving: A Review" was published by researchers at Graz University of Technology (Austria), University of Zagreb (Croatia), AKKA I&S (France). Abstract "Automated driving can no longer be referred to as hype or science fiction but rather a technology that has been gradually introduced to the market. The recen... » read more
