ENRICHME: Enabling Robot and assisted living environment for Independent Care and Health Monitoring of the Elderly(EU Horizon 2020 RIA, 643691 - €543k - Principal Investigator)
This is a collaborative project, involving academic institutes, industrial partners and charity organizations across six European countries. It tackles the progressive decline of cognitive capacity in the ageing population proposing an integrated platform for Ambient Assisted Living (AAL) with a mobile robot for long-term human monitoring and interaction, which helps the elderly to remain independent and active for longer. The system will contribute and build on recent advances in mobile robotics and AAL, exploiting new non-invasive techniques for physiological and activity monitoring, as well as adaptive human-robot interaction, to provide services in support to mental fitness and social inclusion.
Our research contribution in this project focuses in the area of robot perception and ambient intelligence for human tracking and identity verification, as well as physiological and long-term activity monitoring of the elderly at home. Primary tasks include developing novel algorithms and approaches for enabling the acquisition, maintenance and refinement of models to describe human motion behaviors over extended periods. as well as integration of the algorithms with the AAL system.

FLOBOT: Floor Washing Robot for Professional Users(EU Horizon 2020 IA, 645376 - €306k - Principal Investigator)
This is a collaborative project, involving academic institutes and industrial partners across five European countries. The project will develop a floor washing robot for industrial, commercial, civil and service premises, such as supermarkets and airports. Floor washing tasks have many demanding aspects, including autonomy of operation, navigation and path optimization, safety with regards to humans and goods, interaction with human personnel, easy set-up and reprogramming. FLOBOT addresses these problems by integrating existing and new solutions to produce a professional floor washing robot for wide areas.
Our research contribution in this project focuses in the area of robot perception, based on laser range-finder and RGB-D sensors, for human detection, tracking and motion analysis in dynamic environments. Primary tasks include developing novel algorithms and approaches for enabling the acquisition, maintenance and refinement of multiple human motion trajectories for collision avoidance and path optimization, as well as integration of the algorithms with the robot navigation and on-board floor inspection system.

ActiVis: Active Vision with Human-in-the-Loop for the Visually Impaired(Google Faculty Research Award - $55k - Principal Investigator)
The research proposed in this project is driven by the need of independent mobility for the visually impaired. It addresses the fundamental problem of active vision with human-in-the-loop, which allows for improved navigation experience, including real-time categorization of indoor environments with a handheld RGB-D camera. This is particularly challenging due to the unpredictability of human motion and sensor uncertainty. While visual-inertial systems can be used to estimate the position of a handheld camera, often the latter must also be pointed towards observable objects and features to facilitate particular navigation tasks, e.g. to enable place categorization. An attention mechanism for purposeful perception, which drives human actions to focus on surrounding points of interest, is therefore needed. This project proposes a novel active vision system with human-in-the-loop that anticipates, guides and adapts to the actions of a moving user, implemented and validated on a mobile device to aid the indoor navigation of the visually impaired.

Mobile Robotics for Ambient Assisted Living(Research Investment Fund, University of Lincoln - Full PhD Studentship - Supervisor)
The life span of ordinary people is increasing steadily and many developed countries, including UK, are facing the big challenge of dealing with an ageing population at greater risk of impairments and cognitive disorders, which hinder their quality of life. Early detection and monitoring of human activities of daily living (ADLs) is important in order to identify potential health problems and apply corrective strategies as soon as possible. In this context, the main aim of the current research is to monitor human activities in an ambient assisted living (AAL) environment, using a mobile robot for 3D perception, high-level reasoning and representation of such activities. The robot will enable constant but discrete monitoring of people in need of home care, complementing other fixed monitoring systems and proactively engaging in case of emergency. The goal of this research will be achieved by developing novel qualitative models of ADLs, including new techniques for 3D sensing of human motion and RFID-based object recognition. This research will be further extended by new solutions in long-term human monitoring for anomaly detection.
RFID-based Object Localization with a Mobile Robot to Assist the Elderly with Mild Cognitive Impairments(Internally funded, University of Lincoln - Full MSc by Research Studentship - Supervisor)
Solutions for Active and Assisted Living (AAL) like smart sensors and assistive robots are being developed and tested to help the elderly at home. However, it is still very difficult for a robot to understand the context in which its services are supposed to be delivered, even for simple tasks like finding the keys left by a person somewhere in the house. These are practical problems affecting the life of many elderly people, in particular those suffering Mild Cognitive Impairments (MCI). Radio-frequency identification (RFID) technology is a viable option for locating objects in domestic environments. The main aim of this research is therefore to develop a system for a mobile robot to detect and map the position of RFID-tagged objects, exploiting its capability to explore the house and sense the environment from multiple locations. The system will be evaluated in the lab and in real elderly houses.
Other Research Topics
Qualitative Representations for Human Robot Spatial Interaction
Personal robots should provide a range of dedicated services for entertainment, home assistance, etc. Several challenges need to be addressed in order for robots to move around humans swiftly, safely and politely. The Qualitative Trajectory Calculus (QTC) is a powerful method to abstract a large number of possible scenarios for Human-Robot Spatial Interaction (HRSI). In this research, computational models based on QTC are developed to analyse and implement HRSIs for robot's behaviours that are socially acceptable.
Multisensor People Tracking and Recognition with Mobile Robots
In order to operate in human environments, mobile robots must be able to detect, track and recognize people. These are important for the robot to navigate safely and provide user-oriented services. Since humans and animals in general make use of a variety of sensory inputs to perceive the world, it seems quite natural to follow a similar approach with robots, and integrate the information provided by different sensors (e.g. camera and laser). This research aims to implements multisensor solutions to perform simultaneous human tracking and recognition, so that the former can improve the latter, and vice-versa. Probabilistic approaches and Bayesian estimators, such as Kalman or Particle filters, are applied in this research.
Active Vision for Assisted Living and Intelligent Surveillance
There is an increasing need of smart assistive technologies and intelligent surveillance systems for enhancing humans and monitoring people with health conditions. This application area is addressed by the current research with active perception algorithms and cognitive architectures that link high-level reasoning, either human or artificial, to low-level action and perception, such as those relative to the use of portable devices, distributed camera systems and mobile service robots.
