This paper presents a novel Shape Memory Alloy (SMA) linear actuator and its application driving the joints of an anthropomorphic robotic hand. Its main feature is that it is a flexible SMA actuator, it is designed so that it can be bent. The possibility of bending the actuator while preserving its capacity to produce a linear movement allows to use very long SMA wires, able to yield a great linear...
Precision machining of components with tight tolerances requires not only to do a fine presetting of tools, but also to carry out on-line tool-path corrections in order to compensate the form deviations that arise in the workpiece derived from the action of cutting forces. Advanced and expensive technology, such as machine-tools equipped with multiple sensors, are commonly utilized for this purpose...
