A laser cutting system developed by researchers at MIT can detect and differentiate materials, to make informed cutting decisions. The system, called SensiCut, could increase the capabilities of laser cutting systems in applications that involve objects composed of multiple materials. Conventional approaches to material identification in this context often involve cameras, which can make mistakes with visually similar materials, or sticker tags such as QR codes, which could be cut or fall off, or even misidentify a material. Incorrect identification can result in damaged products and...Read full articleRelated content from Photonics MediaARTICLESProbabilistically Programmed Systems See More Like Humans DoMIT researchers have developed a framework to enable machines to see the world more like humans do.
