Abstract
The fibrefed robotic dual-beam optical spectrograph FRODOSpec is one of the main instruments built for use at the Liverpool 2-m robotic telescope located in La Palma. INAOE was the successful tender of the contract for the manufacturing of the red arm optics and lens mounts. The project was developed jointly by INAOE, CIO and IAUNAM. We describe the project main characteristics and the obtained results.
