Variable recruitment in bundles of miniature pneumatic artificial muscles.

Bioinspiration & biomimetics Sep 13, 2016
The natural compliance and force generation properties of pneumatic artificial muscles (PAMs) allow them to operate like human muscles in anthropomorphic robotic manipulators. Traditionally, manipulators use a single PAM or multiple PAMs actuated in ...

Development of a bio-inspired transformable robotic fin.

Bioinspiration & biomimetics Aug 31, 2016
Fish swim by oscillating their pectoral fins forwards and backwards in a cyclic motion such that their geometric parameters and aspect ratios change according to how fast or slow a fish wants to swim; these complex motions result in a complicated hyd...
