Current technology produces a big mass of information. The application of this information gives meaning and purpose to this data. Mobile robots can benefit from this information. This paper proposes a framework to apply semantic information to the navigation of autonomous mobile robots, tracking the robot movement into a semantic trajectory and analyzing the context data on the decision-making process...
Autonomous Mobile Robots should be independent from human assistance. One of the open issues is the ability to manage the energy level to maximize its use and avoid human interaction to rescue a robot without energy. Several works on the literature focus on how to recharge an autonomous mobile robot, proposing hardware modification and complex energy stations. In this paper we propose a new method...
With the increasing use of mobile devices, a lot of tracks of movement of objects are being collected. The advanced trajectory data mining research has allowed the discovery of many types of patterns from these data, like flocks, leadership, avoidance, frequent sequences, and other types of patterns. In this article we introduce a new kind of pattern: a chasing behavior between trajectories. We present...
