RobotSculptor uses a six-axis robot arm to sculpt clay models
Robotic fabrication techniques such as 3D printing enable you to make a copy of a wide variety of items. Actually sculpting something out of clay, however, remains a largely human pursuit. One might also miss the individual style of a sculptor in a finished product.
RobotSculptor, developed by a team of engineers from ETH Zurich and Disney Research, attempts to address both challenges. The system generates toolpaths from a base mesh design and allows artistic input via mouse strokes during the process. A six-axis robot arm then incrementally removes clay from the model-in-progress, using a custom loop tool.
An Arduino Uno-controlled turntable acts as a seventh axis for the robot, giving it the ability to reach different areas of the model in order to create complex 3D shapes.
