Abstract

The paper describes a 3-DoF translational (XYZ) mechanism for the main detector of the EMIR multi-object spectrograph, developed for the GTC telescope. This mechanism is designed for the cryogenic environment (77 K) and consists of a parallel manipulator with flexure joints, actuated by three identical and symmetrically located linear actuators.
