Biesse's Viet Opera R robotic sanding machine allows clients to machine panels in any direction and on different planes, as well as on the inside of profiles and shaped edges. Panels can be machined following the grain of the wood, or against it. 
 
This control is made possible by a new patented "control force" system that regulates the intensity of the abrasive action on the panel, and the simulation of human operators controlling hand held power sanders. Viet Opera R has been selected as a 2016 IWF Challengers Award semi-finalist
 
The Opera R picks up various hand-held sanders, switching from round to square or other shapes, to sand contours, corners and joints similarly to a human operator.
