Persistent Robotic Navigation

Australian Research Council Discovery Project DP110103006





Robot navigation systems based on conventional maps are unable to cope with changes in their environment, constraining their real world application. This project creates lifelong robot navigation systems that explicitly account changes in the environment by using a new type of map based in both space and time. A map in space and time can accommodate changes in the shape of the environment and recover from mistakes. New methods for robot vision will account changes in appearance of places over hours, days, weeks and years. We will demonstrate the new navigation and vision capabilities on robotic platforms that continuously adapt to changes in the environment over the robot's lifetime, establishing a new benchmark in real world robotics.

Persistent Vision-Only Navigation

The aims is to enable a robot to navigate autonomously using purely visual sensors for extended periods of time. 
Active research includes: 

  • Robustness - investigating multi-hypothesis graph-based approaches to dealing with change and uncertainty in both geometry and appearance on a global and local level. 

  • Compact representations to aid localization.

  • Memory based approaches to persistent navigation.

  • Robust recovery behavior to handle the periods of vision blackout during navigation.

Persistent navigation in densely crowded environments

Current state-of-the-art methods to tackle the problems of mapping, localizing, navigating and planning by mobile robots have been shown to produce desirable and promising results when dealing with each of these problems individually. However, there are few mobile robots which are able to demonstrate long-term autonomy using all these methods together while operating unsupervised in a real-life environment. One example of such an environment is a public event. The main characteristic of these events is that they are densely crowded most of the time which introduces a new set of challenges for mobile robots.
