SRS is a European research project for building robust personal assistant robots using ROS (Robotic Operating System) and Care-O-bot (COB) 3 as the initial demonstration platform. In this paper, experience gained while building the SRS system is presented. A main contribution of the paper is the SRS autonomous control framework. The framework is divided(More)
Sentiment analysis has become the heart of social media research and many studies have been applied to obtain users' opinion in fields such as electronic commerce and trade, management and also regarding political figures. Social media has recently become a rich resource in mining user sentiments. Social opinion has been analysed using sentiment analysis(More)

Automated task planning for service robots faces great challenges in handling dynamic domestic environments. Classical methods in the Artificial Intelligence (AI) area mostly focus on relatively structured environments with fewer uncertainties. This work proposes a method to combine semantic knowledge representation with classical approaches in AI to build(More)
The concept of service robotics has grown considerably over the past two decades with many robots being used in non-industrial environments such homes, hospitals and airports. Many of these environments were never designed to have mobile service robots deployed within them. This paper describes some of the challenges that are faced and need to be overcome(More)
Generating plans in real world environments by mobile robot planner is a challenging task due to the uncertainty and environment dynamics. Therefore, task-planning should take in its consideration these issues when generating plans. Semantic knowledge field has been planned as a source of information for deriving implicit information and generating semantic(More)
Unstructured domestic environments present a substantial challenge to effective robotic operation. Domestic environment requires service robots to deal with unexpected environment changes, novel objects, and user manipulations. We present an approach to enable service robots to actively learn high-level skills in an unstructured environment. This involves(More)
This paper introduces the idea of viewing fuzzy modelling and fuzzy system design from a functional analysis perspective. Fuzzy transforms, which are based on the generalised Fourier transform in functional analysis, are proposed. It is demonstrated that, mathematically, a T-S fuzzy model is equivalent to a fuzzy transform. Hence the parameters of a T-S(More)
