“…It is the case of Probo, with 20 dofs in its head, the robot is capable of expressing several emotions [18]. Another example is the robot FACE, mapping with 32 dofs the major facial muscles to simulate realistic facial expressions [14]. Today, the lack of emotion expression of NAO is one of the main limitation for social interaction and studies.…”

Robots can express emotions for better human robot interaction. In this field, NAO robot is a platform widely used. This robot mainly expresses emotions by gestures and colored LED eyes, but, due to its white flat and inanimate face, the robot cannot express facial expressions. This work proposes a pluggable eyebrows device enabling NAO to express anger or sadness while performing other tasks. This device is plug-and-play and directly controllable by NAO's development environments. Additionally, we developed a platform independent mapping of eyebrows angles with emotions. We first conducted an experiment that qualitatively attests the interest of this device. Three following experiments were conducted to: (1) confirm the relation between eyebrows angle and expressed emotion; (2) evaluate different shapes in order to select the most appropriate one; (3) prove that NAO is able to use the eyebrows to express emotions while performing non emotional tasks.

New lightweight, compliant, reliable and cheap contractile linear actuators are demanded today for many fields of application, such as robotics, automation and biomedical disciplines. Within the family of electroactive polymers, dielectric elastomers are rapidly emerging as high-performance transduction materials, resulting particularly attractive in order to accomplish different kinds of tasks. The design of efficient device architectures, capable of taking the most from the material properties with practical solutions, is not trivial. In particular, the state of the art of contractile dielectric elastomer actuators offers device configurations resulting not always of easy fabrication. To overcome this drawback, a new actuating configuration, referred to as 'folded dielectric elastomer actuator', has been recently described. This paper presents prototype samples of this new type of actuator, along with different examples of applications currently being developed.

“…FACE itself is able to analyse the emotional reactions of individuals through optical analyses of facial expressions, to track a human face over time and to automatically store all data (Pioggia et al, 2004). The neuro-computational pre-processing strategy adopted to perceive a subject's face is based on Kohonen Self Organizing Maps (KSOMs).…”

“…INFANOID is an upper-torso child-like robot, capable of pointing, grasping, and of expressing a variety of gestures, while KEEPON is a simple yellow snowman-like robot, both equipped by eye-contact and joint attention functions. [Pioggia 2004, Pioggia 2005 on the other hand follows a biomimetic approach. In FACE the biological behaviour is mimicked by means of dedicated smart soft materials and structures, intelligent control strategy, algorithms and artificial neural networks.…”
