Project name: Autism Diagnostic Observation with Robot Evaluator
Project acronym: ADORE
Dates: 01.09.2014 - 31.08.2018
Total budget: 1,000,000.00 HRK
Funding: Croatian Science Foundation (HRZZ)
Project Number: 93743-2014

The main goal of the ADORE project is the development of a robot-based diagnostic protocol and validation of a robotic diagnostic assistant in clinical settings. The robots are used as ASD co-evaluators to help a human evaluator to assess a child's behavior objectively. To the best of our knowledge, such a robot-based ASD diagnostics system is the first of its kind.

The robot-assisted ASD diagnostic protocol consists of four tasks and is based on the Autism Diagnostic Observation Schedule (ADOS) which is considered to be the “golden standard” of ASD diagnostics. Within the tasks, the robot observes social cues such as eye contact, verbal activity and ability to imitate. Since our goal was to make the robot as autonomous as possible, we modelled the tasks using the Mixed Observability Markov Decision Processes (MOMDPs), which enables the robot to infer the information about the child and control task execution autonomously. On the protocol level, we use the standard Partially Observable Markov Decision Process (POMDP) model which enables the robot to choose tasks of the protocol autonomously and combine observations from tasks into a final assessment of a child’s behavior.

Preparing the robots for a session at the Child Communication Research Laboratory

Clinical trials are performed at the Child Communication Research Laboratory, which is located at the Croatian Institute for Brain Research. During various development stages, more than 50 children have been introduced to the robot. Fifteen of them (7 developing typically, 8 with ASD) were a part of the latest study which showed that, given perfect observations of social cues, our robots are capable of identifying the behavior of the child.

Frano Petric defended his doctoral...

On March 29, 2018 LARICS researcher Frano Petric successfully defended his doctoral dissertation and received a Doctor of Science degree in Electrical Engineering. Frano’s thesis was entitled “Robot-assisted Autism Spectrum Disorder diagnostics using Partially Observable Markov Decision Processes”. Frano will continue his research work within the ADORE project until January 2019. Congratulations!

The main results of his work include:

(i) The model of robot-assisted autism spectrum disorder protocol tasks based on partially observable Markov decision processes which enables automated assessment of the inter action,

(ii) Hierarchical partially observable Markov decision process model for control of the robot-assisted autism spectrum disorder diagnostic protocol,

(iii) Experimental evaluation of the robot-assisted autism spectrum disorder diagnostic protocol by conducting trials with children in clinical setting.
