ADORE
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.

We have some great news for the final month of ADORE project! The paper entitled “Hierarchical POMDP Framework for a Robot-assisted ASD Diagnostic Protocol” has been accepted for oral presentation at the prestigious international conference ACM/IEEE International Conference on Human-Robot Interaction HRI 2019. The conference will be held on March 11-14, 2019 in Daegu, South Korea, and our dr. sc. Frano Petric will do the presentation.
In this paper, we extend our previous work by developing a protocol POMDP model which uses tasks of the protocol as actions. We devise a method to interface protocol and task models by using belief at the end of a task to generate observations for the protocol POMDP, resulting in a hierarchical POMDP framework. We evaluate our approach through an exploratory study with fifteen children (seven typically developing and eight with ASD).
