Research Interests

My research aims to develop mobile robots that can interact autonomously with their environment. To function independently in the real world, a robot must be able to cope with an environment that is constantly changing, sometimes rapidly. The main focus of my work is therefore the development of artificial robot “minds”, capable of perceiving and modelling the world in real time and then responding appropriately.

A robot decides on its actions through knowledge of the world and of its internal state. Historically, this decision making has been rather algorithmic, an approach that is brittle in complex environments. As the role of a robot becomes more complicated, it becomes increasingly difficult for the robot's designer to foresee all scenarios that the robot will encounter and makes devising an optimal program for the robot prohibitively difficult. I am interested in alternative decision making paradigms that enable the robot to display adaptive or creative capabilities. A system with such capabilities requires less effort during design and results in a robot that interacts more naturally with its surroundings.

The focus of my current research work is in machine perception, particularly machine vision. The work spans a wide area, from fundamental problems in feature recognition, through techniques for efficiently utilising the limited sensory resources of a robot system, to high level applications of robot vision.

Future research students

I am always looking for good research students to join our team. If you are interested in a Masters or PhD work in any of these areas (or similar) then please send me an email, *including a CV and complete academic transcript*. Please be aware that I am currently receiving a high volume of supervision inquiries, so I may take a little time to respond.

Possible future projects include the following.
  • Active vision with time constraints; scheduling of feature calculation,
  • Statistical underpinnings of active perception,
  • Vision based estimation of robot pose and ego-motion,
  • Incorporation of robot emotion into active perception,
  • Multi-modal active perception,
  • Incorporation of robot end effector management with active vision,
  • Fast computational structures for active vision systems,
  • Application of active vision techniques to astronomical data processing.
