TECHNOLOGY OVERVIEW

The Robotics Laboratory of Université Laval has developed an innovative spatial motion stage based on a parallel mechanism architecture which has a very large range of rotational movement. The technology consists of a new arrangement of the platform’s drive mechanisms that enables the introduction of additional actuators without introducing antagonistic forces.

Therefore, the problem of singularities is avoided which extends the possible rotation range from about ±45° to ±80° in tilt motion and ±170° in twist motion. The mechanism has unique spherical joints with 308° range of motion that can be use in other mechanisms.
