Alexander Htet Kyaw at the Massachusetts Institute of Technology and his colleagues have developed a robot that can assemble building blocks called voxels to build an object with almost any shape you ask it for.The system first takes a person’s spoken request, transcribes it to text and then converts it into a 3D model using an AI trained on a vast database of pictures from the internet. A computer-aided design program then converts this model into a system of voxel coordinates, which can be assembled by a robotic arm. Watch the video [Source: New Scientist on youtube.com]
