On the Conical Motion of a Two-Degree-of-Freedom Tail Inspired by the Cheetah

IEEE Transactions on Robotics, 2015
An actuated tail can impart large angular impulse over short time spans, but swinging in a plane results in inevitable tail angle saturation. Cheetahs ( Acinonyx jubatus ) are observed swinging the tail in a cone during turns [1] , and this paper develops a simplified two-degree-of-freedom (pitch and roll) rigid tail model to investigate this motion ...

A stick–slip piezo-driven two-degree-of-freedom motion stage without backward motion

Review of Scientific Instruments
This study proposes a two-degree-of-freedom stick–slip piezo-driven motion stage without backward motion. The stage combines a flexible beam structure with the stick–slip effect to achieve high positioning accuracy and structural simplicity. Open-loop experiments verified the role of the flexible beam in suppressing backward motion. Displacement, speed,
