Students at Carnegie Mellon University have taken advantage of one of ABB's industrial robotic arms to create 3D light paintings using the 'light painting' method. The paintings, which consist of around 5,000 different plotted light points, where made with the help of a Microsoft Kinect sensor (for tracking) and a DSLR camera capturing long exposures. More information on this project can be found here. View the video below.
