MIT researchers use 3D technology to create object representations from afar.
A group at the MIT Media Lab has created a machine that replicates whatever you put under its sensors in the form of movable rods installed on a table. The whole thing smacks of the pin art toys from your childhood, with one important distinction: it’s touchless.
Professor Hiroshi Ishii and his students used cameras to create a 3D model of any object that fits under the sensor, which information is then fed to a computer that controls the rods on the table. The invention allows physical replicas to be created from a distance, and it’s amazing to watch:
