Sensor classification methods applied to robotics

Abstract: The data obtained from the robotic instrumentation can be redundant due to the multiplicity of sensors. Additionally, the study of the sensor's data can help in optimization the design of the manipulators. In this line of thought, this paper applies two distinct methods for classification of sensors used in robotics. One of the adopted methods leads to arrange the robotic signals in terms of identical spectrum behavior. The other method is the multidimensional scaling technique applied to the correlation of the signals in the time domain. Both methods conduct to similar results, obtaining three groups of signals: the group of "positions", the group of "currents" and the group of "forces, torques and accelerations".

Starting Building a IT Policy: A Quest to IT Success

Abstract: An organization uses information technology (IT), because the IT is consistent with the functional and operational objectives designed by that organization. The investment that is required to place technological innovation in an organization carries significant weight. This weight can be translated into decision making or monetary costs. It is therefore important that after implementation, ensured close monitoring of their use and such monitoring can take many forms, one of which can be explicit through a usage policy. It is the responsibility of the technology manager, to outline the best policy to use the technology that was adopted first by, taking into account the need of the organization and secondly to ensure the construction of monitoring mechanisms and set up conditions to facilitate its successful use. Therefore, the study of the adoption and diffusion of a technological innovation provides these professionals more tools that can assist in the preparation of these strategies, without forgetting that it is necessary to plan at the user level and not only to assist the management in its objectives.

Fractional Order Dynamics in the Trajectory Planning of Redundant and Hyper-Redundant Manipulators

Abstract: Redundant manipulators have some advantages when compared with classical arms because they allow the trajectory optimization, both on the free space and on the presence of obstacles, and the resolution of singularities. For this type of arms the proposed kinematic control algorithms adopt generalized inverse matrices but, in general, the corresponding trajectory planning schemes show important limitations. Motivated by these problems this paper studies the pseudoinverse-based trajectory planning algorithms, using the theory of fractional calculus.

Low-Cost Embedded System for Customer Loyalty

Abstract: Nowadays, digital marketing has become an indispensable tool for companies to promote and sell high-quality products to cope with increasingly competitive markets. For these to be shaped according to the customer’s interests and preferences, technology has been pushed to evolve every day trying to keep up with high global demand. However, there is a particular problem in identifying and locating people in indoor spaces. Many applications were developed leveraging beacon technology that ranges from user’s localization and indoor navigation to personalized assistants that would assist in the decision-making process. This, however, is still an open problem due to the difficulty in creating scalable indoor navigation systems, that are independent of the physical plan, and lack of precision in the detection of the customer indoor position. This paper will disclose the possibility to develop an efficient, low-cost indoor navigation system that solves both problems. It proposes an improvement on the accuracy of customer-beacon proximity distance, and a plan-free navigation method is proposed which allows customers to travel from a position to a specific beacon. Moreover, we integrate this with the concept of proximity marketing to embed the system in a physical context, focused on product promotions to increase customer loyalty.
