The coexistence of service robots in social environments has been intensified in recent years, demanding Human-Robot Interaction (HRI) increasingly fluid and necessary. In this context, the present work aims to develop an architecture, called Erika. Erika provides a chatbot to interact by voice and text commands with a service robot, who implements...

Social robotics is an emerging area that foster the integration of robots and humans in the same environment. With this objective, robots include capacities such as the detection of emotions in people to be able to plan their trajectory, modify their behavior, and generate a positive interaction with people based on the information analyzed. Severa...

In the context of Human-Robot Interaction (HRI), emotional understanding is becoming more popular because it turns robots more humanized and user-friendly. Giving a robot the ability to recognize emotions has several difficulties due to the limits of the robots' hardware and the real-world environments in which it works. In this sense, an out-of-ro...

Social robotics is an emerging area that is becoming present in social spaces, by introducing autonomous social robots. Social robots offer services, perform tasks, and interact with people in such social environments, demanding more efficient and complex Human–Robot Interaction (HRI) designs. A strategy to improve HRI is to provide robots with the...

Emotion recognition is a strategy for social robots used to implement better Human-Robot Interaction and model their social behaviour. Since human emotions can be expressed in different ways (e.g., face, gesture, voice), multimodal approaches are useful to support the recognition process. However, although there exist studies dealing with multimoda...

For social robots, knowledge regarding human emotional states is an essential part of adapting their behavior or associating emotions to other entities. Robots gather the information from which emotion detection is processed via different media, such as text, speech, images, or videos. The multimedia content is then properly processed to recognize...

The Robust Transform based on the Weighted Median operator algorithm calculates the transform of a signal when it has been exposed to impulsive noise. Since this algorithm demands very long execution time, it is not useful for real time signal processing systems. In this context, this work presents several strategies to improve its performance, suc...
