Linear motion
Robot handles parts with ease
Creating a robot for small parts handling calls for a machine design that is both highly dynamic and extremely precise. With the Galileo Sphere, the Italian Mechatronic System Company has built a robot that combines the advantages of linear and direct drives in one system...
