Conference Paper
Human-machine interactions are likely to require synergistic multidisciplinary research efforts for supporting a paradigm shift towards collaborative-oriented use cases. An essential aspect of collaboration is trust and in order to establish it there is need for Human-Machine Mutual Understanding (HMMU). We argue that achieving HMMU will require ev...
Conference Paper
In this paper, we present a generic framework for knowledge man- agement and automated reasoning (KMARF) as an enabler for intelli- gent adaptive systems. KMARF targets multiple reasoning problem classes (such as planning, veri cation and optimization) that can share the same underlying system state representation. e idea behind KMARF is to automat...

Cyber-Physical Systems in general, and Intelligent Transport Systems (ITS) in particular use heterogeneous data sources combined with problem solving expertise in order to make critical decisions that may lead to some form of actions e.g., driver notifications, change of traffic light signals and braking to prevent an accident. Currently, a major p...

Internet of Things (IoT) applications transcend traditional telecom to include enterprise verticals such as transportation, healthcare, agriculture, energy and utilities. Given the vast number of devices and heterogeneity of the applications, both ICT infrastructure and IoT application providers face unprecedented complexity challenges in terms of...
Article
This paper presents the evolution of a software platform for supporting experimentation in mobile robotics as part of teaching and researching activities. Starting with Web-based laboratories (WebLabs) in the early 2000s the platform kept evolving according to the networking and distributed computing trends since then. In addition to the physical r...
Chapter
The Internet of Things (IoT) is considered the driving force behind the next Internet revolution, with major technological and cultural impacts. Although the term “Internet of Things” has just recently became widespread, IoT relies on several well-established concepts, such as ad hoc and wireless sensor networks, ubiquitous computing, and Cyber-Phy...
Conference Paper
As mobile robots become part of large net-worked infrastructures, concerns about the integration of robots into distributed applications arise. Due to the predominance of the Web protocols, it is natural mo-bile robots to employ such protocols for interacting over the network with other applications. Information trans-fer protocols such as HTTP and...
Conference Paper
Technologies such as Brain-Computer Interface (BCI) and Electromyography (EMG) allow people with limited mobility to interact with devices such as computers, home appliances and mobile robots. However, low cost BCI and EMG have not matured yet. Moreover, these technologies present relative low signal-to-noise ratio and classification accuracy. In c...
Conference Paper
A capacidade motora de um individuo, como caminhar, pode ser facilmente comprometida por uma variedade de fatores, como traumatismo na coluna, acidentes vasculares cerebrais, amputacao de membros, esclerose multipla, etc. Algumas tecnologias podem ser utilizadas para auxiliar estes individuos melhorando sua mobilidade e qualidade de vida. Estas tec...
Conference Paper
This paper presents a distributed navigation strategy for mobile robots in environments instru-mented by wireless sensor networks (WSN). The strategy distributes the navigation components across the mobile robot, stationary processing nodes outside the robot and WSN nodes. The WSN supplies a navigable path con-sisting of a sequence of WSN nodes tha...

Conference Paper
A trend in today’s mobile robotics is to perform the control of mobile robots in a distributed fashion. This control scheme requires a wireless communication network connecting the robot to the other existing devices in the environment. WiFi and Bluetooth are examples of such networks. Ad-hoc networks such as wireless sensor networks (WSN) can be d...
Conference Paper
This paper presents the design of a cloud computing environment for networked robotics. The environment aims to support distributed robotics applications that require large shares of computing resources and very low communication delays. Networked robotics applications are built above these services and run on virtualized environments deployed on p...
Conference Paper
Most of the environments where mobile robots are deployed offer a comprehensive networking infrastructure. In order to take part of these environments, mobile robots must enhance not only their communication capabilities, but also their interaction capabilities. Current robotic frameworks are oriented to gather data from the robotic sensors and to...

We will explore the interplay between multi-objective computational intelligence approaches and autonomous robotics for managing complex logistics operations. In typical scenarios, each node of a supply network e.g. suppliers, warehouses, retailers has little information about the current states of the nodes affecting them. Such lack of information leaves no choice but to react to incoming orders from other nodes by relying on static business policies in order to fulfill production, inventory replenishment, storage, and delivery requests. As a consequence, achieving adequate service levels under acceptable costs can become very challenging. Vendor-Managed Inventory (VMI) approaches, where the supplier assumes full responsibility of replenishing the retailers inventories, can alleviate this problem by taking advantage of increased integration between nodes and conducting proactive automated operations for reducing supply demand gaps. This project aims to model and simulate intelligent, automated VMI strategies allowing for efficient real-time integration of warehouse operations with multi-retailer inventory replenishment tasks. We will design the simulated environment with V-REP, a comprehensive robot simulator, where an autonomous industrial robot receives instructions generated by a multi-objective evolutionary algorithm running in real-time, aiming to simultaneously maximize profit and minimize shortage and surplus risks, while deciding on-the-fly which and how many products should be delivered to which retailers and when. Action selection is performed by monitoring inventory levels and stochastic customer ordering events at the retailers. In summary, the project initial goals are (1) to expose multiple criteria decision-making concepts for supporting real-time expression of different degrees of risk aversion preferences; (2) to expose how retailer inventory control can lead to a sequence of warehouse pickup and delivery problems with deadlines; and (3) to demonstrate the cascading effects on the simulated robot behavior of demand events in the retailers side that can disrupt the supplier’s service level capacity.
