The visual detection and identification of robots will become more and more important as individual robots will need to interact and in some cases collaborate with other robots while performing different tasks in a common environment. The efficient detection and identification of other robots is a very important issue as most mobile robots have low-processing capabilities and need to manage several different processes in real time (e.g., walking machine). In collaborative scenarios, robots will have to determine behaviors of other robots, in addition to their location. One of the important clues to predicting the future behavior of a robot is to know its line of gaze. In addition, surveillance and/or augmented reality systems operating in scenarios with the presence of robots will also require detecting and identifying them, as well as their behaviors.
