Researchers from MIT have developed an Alexa-like system "ComText" - for "commands in context" - that allows robots to understand a wide range of commands that require contextual knowledge about objects and their environments.
Most modern websites store data in databases, and since database queries are relatively slow, most sites also maintain so-called cache servers, which list the results of common queries for faster access.
Manisha Mohan, an Indian scientist at the Massachusetts Institute of Technology (MIT), has developed a sticker-like wearable sensor that can detect sexual assault in real time and quickly alert nearby people as well as the victim's friends and family to seek help.
MIT scientists have developed a system of eight robotic drones that can fly through the air as well as drive on ground, efficiently navigating cityscapes with parking spots, no-fly zones and landing pads. They tested the robots navigating from a starting point to an ending point on a collision-free path for successful results.
