Beschreibung
Zusammenfassung:	A fluidic artificial muscle actuator comprises at least one inflatable bladder defining a first inflatable segment (11) coupled to a first member (14) and to a second member (134) arranged at opposite ends of the first inflatable segment, and a second inflatable segment (12) coupled to a third member (135) and to a fourth member (15) arranged at opposite ends of the second inflatable segment, and an effector coupled to the first inflatable segment and to the second inflatable segment for providing an actuator output. The first inflatable segment is configured to contract in a longitudinal direction (101) with increase in fluid pressure in the first inflatable segment and the second inflatable segment is configured to extend in the longitudinal direction with increase in fluid pressure in the second inflatable segment.
