Perspectives in SMA actuators: a frequency response and power consumption study
نویسندگان
چکیده
Bio-inspiered actuators are one of the most interesting topics in robotics. In particular, shape memory alloy (SMA) based actuators are one of these emerging technologies inspired by animal muscles. The main advantages of this type of actuators are their high force-weight ratio and its noiseless operation. Nonetheless, other features regarding frequency response and power consumption make their applicability not a viable solution to several problems. The objective of this paper is to clarify these aspects and study the the applicability of this sort of actuators. To do so, some experiments applied to the control of a robotic finger are provided. Experiments were targeted to the study of frequency response improvement and power consumption.

Nonlinear Analysis of a Flexible Beam Actuated by a Couple of Active SMA Wire Actuators
There are two different ways of using SMA wires as actuators for shape control of flexible structures; which can be either embedded within the composite laminate or externally attached to the structure. Since the actuator can be placed at different offset distances from the beam, external actuators produce more bending moment and, consequently, considerable shape changes with the same magnitude...
