    About me

    I teach and do scientific research in the fields of artificial intelligence, robotics and human factors engineering. I am head of the Applied Artificial Intelligence Laboratory in the Discipline of Information Technology, Mathematics & Statistics. I’ve studied psychology, computer science and engineering for over forty years. During this time I’ve designed and built many artificial intelligence programs and robots, including the BEELINE natural language understanding agent, a walking biped (Tarbaby), an innovative floor cleaning robot (CURI5), a hexapod (Mascot), the CG-FGP system for computing with emotions and an experimental Programming by Demonstration learning program for eye-hand manipulation in robot workcell.

    My current projects include the NXT field robot and atmospheric sampling using drones. I expect to be developing agricultural service robots in the near future.

    I teach the undergraduate Intelligent Systems and Human-Computer Interaction units, and the postgraduate Human Factors in IT unit. I am the Chair of the Honours program within the IT Discipline.

    I currently supervise two postgraduate students, one working on pollution monitoring instrumentation for drone air sampling and another on generating natural language for an automated pyschotherapy agent. Another PhD student of mine recently completed his thesis in robotics – so I am now looking for other keen robotics students.

    Teaching area

    I currently teach:

    BSC150 What is Science – undergraduate breath unit on the philosophy of science, taken by all Bachelor of Science students.

    ICT319 Intelligent Systems – undergraduate artificial intelligence unit. This is also taught as an articulation in Singapore.

    ICT396 Human Interface Design – undergraduate topic about basics of design and construction of interfaces for computers and computerised machines. This is also taught as an articulation in Singapore.

    ICT576 Honours in Information Technology Literature Review – Honours unit requiring students to develop a complete literature review as part of their thesis.

    ICT612 Human Factors in Information Technology – a collection of advanced readings in interface design, social impact of advanced technologies, including a “future interface” design project.

    Research areas

    I’m interested in all kinds of artificial intelligence and many aspects of cognitive psychology, but I’ve had to restrict myself to only a few sub-areas to avoid spreading myself too thinly!

     

    Conceptual models for natural language understanding.  A long-time interest in and contributor to the literature on conceptual structures, especially for language comprehension, has stayed with me. I have built up an an elaborate software system based on conceptual graphs that can read paragraph- length texts, perform simple commonsense reasoning, and produce simple textual output. Recently, I have used this as the basis for experiments computing with and using language about emotions.

     

    Student teleoperates experimental robot

    Teleoperated field robots for maintenance tasks.

    Research students and I have  pursued the idea that teleoperation of working field robots should give way to more and better automation if the machines are to reach their full potential. One experiment in the Applied AI Lab concerns the Corobot, a small wheeled machine which has been modified to allow it to serve as a test platform for our ideas about adjustable automation. These include the novel idea of ‘assigned responsibility’ in which a goal-accomplishment plan forms a shared representation of a task between a robot and its human operator and on which an explicit work contract clearly assigned responsibility for tasks between the human and automated functions within the robot. This implies a special new kind of interface which is designed to reduce mental stress and free the operator from the need for continuous supervision of the work.

     

    Mascot hexapodal robot and portable control stationMascot is a field robot which which I have been developing for several years. This six-legger continues my interest in legged mobililty as an alternative to wheels, especially in very rugged terrain and of applying robots to the task of maintence at remote, difficult or dangerous work sites. There are a good many issues concerning the operation and practicality of such a machine and how well it can be remotely controlled, even before we come to the question of automating the machine so it can become more independent of direct human supervision. Needs a good student to take an interest in it and develop it further!

    Current projects

    Currently, I’m working on the following projects:

    Artist's conception the finished Murdoch Drone Workshop

    UAVs for Air Pollution Monitoring. Murdoch University is investing heavily in drone technology. I am working on a number of projects aiming to develop this technology for use in scientific applications, such as with PhD student Goruck Soubons with his air pollution monitoring and precision agriculture with the State Agricultural Biotechnology Centre. The university now owns several multirotor aircraft, and I hold a CASA license to fly them.  We have now refurbished a building for our new Drone Research Facility, where development of our science projects will be conducted. Murdoch University is also looking into the possibility of a “drone hub” – a centre for commercial drone development – to be based at Murdoch’s Whitby Falls Farm.

     

    NXT Field Robot in an agricultural setting

    NXT Robot. I am currently building a new robot designed to try out some of the latest ideas in teleoperation and machine learning. The robot will likely find applications in the monitoring and treatment of plants on farms. If it develops as expected, the first experiments will test the new Visual Teach & Repeat method for getting the mobile machine to target locations after only one manually guided trip there. Later experiments will try to extend this one-trial learning to simple manipulation tasks, using a pair of lightweight 7-DoF arms.

     

    Semantic and conceptual analysis

     

    Natural Language Generation for Automated Psychotherapist.  In work with DIT student Beena Kishore, I find myself returning to the field of natural language processing after being out of the game for many years. Beena is developing sophisticated methods of natural language generation for an automated pyschotherapeutic agent, which can respond to both the conceptual content of utterances and the emotional state of the patient.

     

    Awards and grants

    2010 Murdoch Research Capacity Fund (with G. Bell) 07177 “Building A Cross-Disciplinary Applied Artificial Intelligence Group”.
    This $27,000 grant has established and equipped the Applied Artificial Intelligence Laboratory within the School of Engineering and Information Technology.

    2003 ARC Linkage Grant (with A. Turk & D. Varan) LE0347194 “Interactive Television Audience Research Laboratory: Infrastructure, Equipment”.
    This $411,000 grant established the Audience Lab at ITRI, by providing for major equipment purchase installation and testing.

    Doctoral and masters supervisions

    I currently supervise two postgraduate students:

    Beena Kishore
    A Natural Language Generation System for Patient Theory’   The aim of this work is to create a language generation system that can produce well-formed English sentences make appropriate responses in therapeutic conversations dealing with human experiences of some complexity. In particular, the system will be capable of dealing with expressions with emotive content, a neglected aspect in this field. It will develop the notion of affective-model-based adaptation of high-level expressive forms to select and customise the content from a conceptual graph knowledgebase by an emotion tracking model and a biographical profile of the patient.

    Goruck Soubans
    ‘Enhanced Field-sampling and Investigation of Emissions from Blasting Operations in Mining’ In an effort to reduce the environmental impact of toxic chemicals from explosives used in the mining industry, this project involves flying instrument-bearing drones through the smoke clouds to sample the substances formed. These samples will then be analysed to better understand the unfolding chemistry of explosive reactions.

     

    Recent Graduates

    Engineering Masters Student Aubrey Cason graduated in 2018 after completion of his thesis entitled ‘An Investigation into the Design of Rotorcraft Controllers for Low Density, Low Pressure or Extra-terrestrial Application.’ This described aerodynamic experiments aimed at designing a small rotorcraft capable of flying in the atmosphere of Mars.

    DIT Student Jeremy Nunn graduated in 2017 after completing a project entitled
    ‘Towards a Unified Methodology for Supporting the Integration of Data Sources for use in Web Applications’ This work aimed to create a unified top-down data integration methodology instantiated with a framework that can aid developers in their integration process. It could act as a scaffold to support the specific technical approach chosen for the integration process. The framework was to assist in the integration of data sources to support web application builders. The thesis presented the rationale for the framework based on an examination of the range of applications, associated data sources and the range of potential solutions. The framework was evaluated using several case studies.


    PhD student Nicolas Small
    graduated in 2016, with a thesis entitledAssigned Responsibility: An Architecture for Mixed Control Robot Teleoperation’.  This developed a new model for the adjustable teleoperation of robots, based on an explicit allocation of tasks, shared between the human operator and the robot, guided by their respective skills and capabilities. To accomplish this, every task the robot is requested to perform needed to be broken down into simple sub-tasks, which then can be allocated. These ideas were formally tested in experiments using a real service robot and operators in simulated maintenance task scenarios, demonstrating their feasibility empirically.

    PhD student Richard Adams graduated in 2013, with a thesis entitled ‘The Advanced Data Acquisition Model (ADAM): A Process Model for Digital Forensic Practice’ Evidence relating to computer crime is significantly different from that associated with the more “traditional” crimes for which there are well-established standards, procedures and models. This thesis developed a new process model for digital data acquisition that addressed both the practical needs of practitioners working in different areas of the field and the expectation of law courts for a formal description of the process undertaken to acquire digital evidence.
