There is a new robot called YuMi IRB 14000 that creates sculptures with a hot wire. Similar robots build by layering material and use multiple steps to smooth and define curved features. This robot works by subtracting material and works around curved edges with ease.
YuMi IRB 14000 has two arms that hold a non-stretchable wire to slice through polystyrene foam blocks and other similar material. Scientists carefully considered the restrictions of this wire. Although it is flexible, it holds the same length to give consistent results.
The sculptures cannot be completed in a single pass through the material. However, the robot can make exact measurements to plan the next cut without unintentionally cutting a different part of the sculpture. The sequences are planned to ensure each complex design is accurate.
Researchers can now bring improved speed and efficiency to creating curved surfaces on 3D models with advanced robots.
