Robots operating in unstructured environments must be capable of safely handling unexpected collisions with objects existing in the surrounding area, possibly without stopping the task execution. This letter proposes a tactile feedback control law allowing the robot to apply bounded contact forces in reaction to physical collisions while...

It is a well-established fact in the field of Human-Robot Interaction that the personality a social robot is endowed with (i.e., the one it expresses by its gestures and words) plays a key role towards the engagement experienced by any person interacting with it. In this article, we address the problem of designing the conversational style of a...

In this article we present a sensing device to enable safe and reactive human-robot interaction for collaborative tasks involving industrial heavy-duty robots. We have designed and implemented an handle covered with artificial skin intended to provide commands in response to operator's touch. The tactile processing system is capable to...
