A camera positioner driven by muscle-like actuation
2012
2012 4th IEEE RAS & EMBS International Conference on Biomedical Robotics and Biomechatronics (BioRob)
Numerous camera positioning mechanisms exist, but their actuation has little in common with the human eye whose motion they are meant to replicate. Piezoelectric cellular actuators, a novel biologically inspired technology, have much more in common with the recti muscles that position the human eye than traditional actuators have. This work explains how to select multi-layer nested compliant strain amplification mechanisms that can scale up the displacement of piezoelectric stacks to the range
