Risk Analysis, An International Journal has published a special issue, 'Social Science of Automated Driving,' which features several articles examining the human side of automated driving, focusing on questions about morality, the role of feeling, trust and risk perceptions.
In a paper published today in Science Robotics, engineers at Brigham Young University detail new technology that allows them to build complex mechanisms into the exterior of a structure without taking up any actual space below the surface. This new class of mechanisms, called 'developable mechanisms,' get their name from developable surfaces, or materials that can take on 3-D shapes from flat conformations without tearing or stretching, like a sheet of paper or metal.
Process developed at MIT could turn concentrated brine into useful chemicals, making desalination more efficient.
Desert ants are extraordinary solitary navigators. Researchers at CNRS and Aix-Marseille University, in the Institut des Sciences du Mouvement -- Étienne Jules Marey (ISM), were inspired by these ants as they designed AntBot, the first walking robot that can explore its environment randomly and go home automatically, without GPS or mapping. This work, published on Feb. 13, 2019, in Science Robotics, opens up new strategies for navigation in autonomous vehicles and robotics.
Development outcomes along streetcar corridors can't be entirely attributed to the presence of the streetcar, researchers found. Streetcar investment is commonly accompanied with a healthy incentive package, for example.
The heaviest vehicle to successfully land on Mars is the Curiosity Rover at 1 metric ton, about 2,200 pounds. Sending more ambitious robotic missions to the surface of Mars, and eventually humans, will require landed payload masses in the 5- to 20-ton range. To do that, we need to figure out how to land more mass. That was the goal of a recent study.
Before the age of GPS, humans had to orient themselves without on-screen arrows pointing down an exact street, but rather, by memorizing landmarks and using learned relationships among time, speed and distance. They had to know, for instance, that 10 minutes of brisk walking might equate to half a mile traveled. A new Johns Hopkins study found that rats' ability to recalibrate these learned relationships is ever-evolving, moment-by-moment.
While most hearing experts would say an eardrum is required for long distance hearing, a new study from Binghamton University and Cornell University has found that Aedes aegypti mosquitos can use their antennae to detect sounds that are at least 10 meters away.
The small size and relatively low cost of CubeSats have made them a popular choices for commercial launches in recent years, but the process to propel such satellites in space comes with a number of problems. Purdue University researchers have developed a technology to address one key problem - the uncertainty of ignition system that initiates the propulsion system of the CubeSats. Current ignition systems are unreliable and can be subject to significant and irreversible damage.
Motor vehicle crashes are a leading cause of death and injury in the United States. Emergency medical service (EMS) response time is a factor with the potential to influence survival. This study examined EMS response times to motor vehicle crashes in nearly 2,300 US counties from 2013 to 2015.
