Compliant 3PRS

Name of the prototype: Compliant 3PRS
Belonging to the project: Zabalduz 2012 (University of the Basque Country) & MEDUSA (Spanish Government)


compliant 3PRS_3This compliant parallel mechanism with 3 identical limbs (prismatic joint – revolute joint – spherical joint) has 3 degrees of freedom (DOF) — two rotations about X- and Y-axes and a translation about Z-axis. The use of revolute and spherical hinges allows a precise motion without backflash or friction. The movements archived are a vertical motion of +/- 2 mm and a tilt of 1º.
