Robotics to enhance independence & safety for dementia patients in the home
Lead Research Organisation:
Imperial College London
Abstract
How can interactive ‘social’ robots help improve the lives of people with dementia? We aim to exploit the exciting potential of artificial intelligence (AI) to improve dementia care. We are aiming to develop a family of robotic devices that can engage people living with dementia, helping improve safety in the home and enhancing quality of life.
We will begin by designing social robotic systems that can respond to safety alerts within smart homes. Once triggered, the robot will engage with the individual and act to reduce risks. This may involve directing them to address the hazard – or deploying automated tools that can do so and deciding to call carers or medical support.
We plan to exploit existing commercial technologies (e.g. Amazon Alexa) and grow into development of bespoke devices. We will closely involve people with dementia, family and carers during the design process to define the characteristics of prototype devices and test these to ensure these robots are safe, accessible and enjoyable for people to engage.

Technical Summary
The UK Dementia Research Institute (UK DRI) is an initiative funded by the Medical Research Council, Alzheimer's Society and Alzheimer's Research UK. Funding details for UK DRI programmes will be added from 2020.
Interactive ‘social’ robots have laboratory established capacity used to engage and stimulate people living with dementia. They can: (a) undertake diverse behaviours; (b) collect rich data; (c) change the environment and (d) respond appropriately in a flexible, task-dependent manner. They provide a way to continuously monitor the home and engage with people to support behaviour or to provide companionship. However, their clinical potential is untapped and development of robotics for dementia care is at an early stage.
We will develop an automated ‘family’ of robotic devices focusing on improving safety in the home and enhancing the quality of life for a person living with dementia. The robotic devices will be designed to be safe, accessible and enjoyable to engage with. A design sprint will be used to define key features and functionality. The team will develop a small number of exemplars providing proof-of-principle. For example, they will develop robotic systems to respond to (a) environmental alerts produced by the Healthy Home (e.g. noting a kitchen spillage or cooker left on); and (b) alerts related to the person with dementia (e.g. responding to signs of agitation or injury). Following an alert, the robot device will engage with the individuals and, guided by information from a smart environment, will act to reduce risks. The simplest solution may be to direct the owner (help to clean a spillage), but it may be possible to deploy automated tools to achieve similar ends. In the case of agitation, for example,, if a cause can be identified such as confusion simple interventions may be effective and interactions through a conversational agent or social robot may be directly beneficial.
A related focus for the programme will be to develop effective methods of communication between people with dementia and robotic devices. The design process will evaluate the impact of variations in features such as configurable visual appearance, voice characteristics, movement, and tactile features that are optimal for the individuals involved, and the team will produce ‘lightweight’ prototypes for testing purposes.).
Main objectives include
1. To produce robotic devices with elementary AI that are capable of interacting with people living with dementia.
2. To integrate robotic devices within smart living environments to monitor and manage the environment for improved safety and quality of life.
3. Draw from user-centred design to define the characteristics of robotic devices suitable for these tasks

PI Contribution | Parkinson's disease (PD) is the second most common neurodegenerative disease worldwide. Bespoke subject-specific treatment (medication or deep brain stimulation (DBS)) is critical for management, yet depends on a precise assessment cardinal PD symptoms - bradykinesia, rigidity and tremor. Clinician diagnosis is the basis of treatment, yet it allows only a cross-sectional assessment of symptoms which can vary on an hourly basis and is liable to inter- and intra-rater subjectivity across human examin- ers. Automated symptomatic assessment has attracted significant interest to optimise treatment regimens between clinician visits, however, no wearable has the capacity to simultaneously assess all three cardinal symptoms. Challenges in the measurement of rigidity, mapping muscle activity out-of-clinic and sensor fusion have inhibited translation. In this study, we address these issues through a novel wearable sensor system and learning algorithms. We further address major thrusts in brain machine interface (BMI) is to establish a robust, bi-directional direct link between the central nervous system (CNS) and artificial devices (e.g. medical implants, artificial organs, neural stimulators, robotic limbs, etc) through the basal ganglia with PD patients in possession of implants associated with deep brain stimulation. Our team has developed wearable sensors and algorithms to map neural activity for diagnosis of PD and human-robot interface. |
Collaborator Contribution | The University of Oxford and MRC Brain Network Dynamics Group hosts neurological and clinical research aspects of this project. They have directed medical experiments of the hardware on PD patients and deep brain recording experiments as correlated to motor control. |

PI Contribution | With the growing number of the aged population, the number of Parkinson's disease (PD) affected people is also mounting. Unfortunately, due to insufficient resources and awareness in underdeveloped countries, proper and timely PD detection is highly challenged. Besides, all PD patients' symptoms are neither the same nor they all become pronounced at the same stage of the illness. Therefore, this work aims to combine more than one symptom (rest tremor and voice degradation) by collecting data remotely using smartphones and detect PD with the help of a cloud-based machine learning system for telemonitoring the PD patients in the developing countries. Our laboratories have developed sensors and machine learning algorithms for PD that are supporting translation in LMICs through our partners in Bangladesh. |
Collaborator Contribution | UIU Bangladesh has developed a system that receives rest tremor and vowel phonation data acquired by smartphones with built-in accelerometer and voice recorder sensors. The data are primarily collected from diagnosed PD patients and healthy people for building and optimizing machine learning models that exhibit higher performance. After that, data from newly suspected PD patients are collected, and the trained algorithms are evaluated to detect PD. Based on the majority-vote from those algorithms, PD-detected patients are connected with a nearby neurologist for consultation. Upon receiving patients' feedback after being diagnosed by the neurologist, the system may update the model by retraining using the latest data. Also, the system requests the detected patients periodically to upload new data to track their disease progress. |
