Robots learn to shape letters using Play-Doh

Humans aren't the only ones working with Play-Doh. MIT CSAIL researchers have created a system, RoboCraft, that teaches robots how to work with the kid-friendly goo. The platform first takes the image of a shape (in this case, a letter of the alphabet) and reinterprets it as a cluster of interlocking particles. The bot then uses a physics-oriented neural network to predict how its two "fingers" can manipulate those spheres to match the desired outcome. A predictive algorithm helps the machine pl...
