By looking at the minute vibrations in high speed video, researchers at the Department of Engineering of the Catholic University of America have created a method for extracting sound data from high-speed silent video footage. From the release: The authors used a subset-based image-correlation approach to detect the motions of points on the surface of an object, capturing target images with… Read More

I rarely like to focus on military robots but this video is fascinating. It talks about the SWARM program, a system for controlling multiple boats in a body of water and ensuring they don’t crash into each other and can easily swarm on another ship as needed. These boats, which are connected via software called Control Architecture for Robotic Agent Command and Sensing, can be armed but… Read More
