Characterising and suppressing vortex induced vibration. Vortex-Induced Vibration has become the design limiting factor in offshore design of elements such as the flexible pipelines that bring oil and gas to the surface. With rising oil and gas prices it is becoming more economic to explore such resources in deeper waters, which exacerbates the problem. Currently, high factors of safety must be used in the design of such pipelines because of our current lack of understanding of when the vibratio ....Characterising and suppressing vortex induced vibration. Vortex-Induced Vibration has become the design limiting factor in offshore design of elements such as the flexible pipelines that bring oil and gas to the surface. With rising oil and gas prices it is becoming more economic to explore such resources in deeper waters, which exacerbates the problem. Currently, high factors of safety must be used in the design of such pipelines because of our current lack of understanding of when the vibrations occur and their frequency and amplitude. This study will provide insight into the character of such vibrations and also look at means of suppressing them.Read moreRead less
Automated vision-based aircraft collision warning technologies. Australia is a sparsely populated country with a number of unique airspace features. This project will investigate novel vision-based collision warning systems that can improve safety for piloted aircraft and also help achieve integration of UASs (Uninhabited Aerial Systems) into national airspace. The benefits of UAS technologies are particularly relevant to Australia, as governments and industry struggle to cope with providing equ ....Automated vision-based aircraft collision warning technologies. Australia is a sparsely populated country with a number of unique airspace features. This project will investigate novel vision-based collision warning systems that can improve safety for piloted aircraft and also help achieve integration of UASs (Uninhabited Aerial Systems) into national airspace. The benefits of UAS technologies are particularly relevant to Australia, as governments and industry struggle to cope with providing equivalent levels of service to remote communities over vast distances (or border protection of vast regions). The population base of Australia requires that cost-effective solutions are sought to meet this end. Read moreRead less
Automated helicopter hover and recovery system for operations at sea. The small size and simplicity of the integrated system outlined in this project will significantly improve the effectiveness of maritime surveillance for homeland security whilst enabling substantially lower operational costs. The proposal aims to develop control and sensing techniques, enabling small rotary wing unmanned air-vehicles (UAVs) weighing less than 100 kgs to operate from small-size vessels. This will be achieved ....Automated helicopter hover and recovery system for operations at sea. The small size and simplicity of the integrated system outlined in this project will significantly improve the effectiveness of maritime surveillance for homeland security whilst enabling substantially lower operational costs. The proposal aims to develop control and sensing techniques, enabling small rotary wing unmanned air-vehicles (UAVs) weighing less than 100 kgs to operate from small-size vessels. This will be achieved by resolving the current lack of integration between ship motion and the unmanned vehicle guidance systems. The proposed research will make substantial contributions in areas of ship motion prediction and sensing and hover control of tethered and non-tethered small helicopters.

Vision Based Guidance, Navigation and Control of a Tail-Sitter Unmanned Aerial Vehicle. The development of a high precision visual guidance system for vertical takeoff and landing UAVs will significantly enhance their operational effectiveness by allowing them to land accurately on the back of small vessels or in confined clearings. Together with the extra navigation-system redundancy vis-a-vis GPS system failure and the ability to self-identify reasonable emergency landing sites, the proposed v ....Vision Based Guidance, Navigation and Control of a Tail-Sitter Unmanned Aerial Vehicle. The development of a high precision visual guidance system for vertical takeoff and landing UAVs will significantly enhance their operational effectiveness by allowing them to land accurately on the back of small vessels or in confined clearings. Together with the extra navigation-system redundancy vis-a-vis GPS system failure and the ability to self-identify reasonable emergency landing sites, the proposed vision-based system represents a significant capability improvement over what is currently available. It will thus enhance the ability of defence and civil-defence units to patrol Australian borders effectively and to react to threats. It will also have significant export potential to allied nations.Read moreRead less
Image-based teleoperation of semi-autonomous robotic vehicles. This project will contribute strongly to Australia's robotic service industry in the development of semi-autonomous robotic inspection vehicles by; developing core technology in image-based teleoperation, training experts in the area, promoting the study of this topic within the Australian academia, and developing test facilities and prototype vehicles.

This project will contribute strongly to Australia's robotic service industry in the development of semi-autonomous robotic inspection vehicles by; developing core technology in image-based teleoperation, training experts in the area, promoting the study of this topic within the Australian academia, and developing test facilities and prototype vehicles. Robotic inspection vehicles have the potential to replace direct human presence in difficult, dangerous or simply uncomfortable inspection tasks such as; inspection of industrial pressure vessels, piping and conduits in factories or mines, undersea cabling, inspection of bridges, dams and other large scale civil buildings, amongst many other possibilities.Read moreRead less
Image Based Visual Servo Control of Dynamic Under-Actuated Systems. The project builds on earlier work on visual servo control of under-actuated rigid body dynamics to develop and implement sophisticated and robust image based visual servo control for a wide class of under-actuated and fully actuated dynamic systems. The scope of the project extends far beyond basic testing of preliminary results to address key technical issues facing visual servo control algorithms at this time.

The scope of the project extends far beyond basic testing of preliminary results to address key technical issues facing visual servo control algorithms at this time. The project is strongly motivated by the host of emerging applications for visual servo control of unmanned aerial vehicles. The experimental program within the project is based on control of a four rotor VTOL `hoverbot'.Read moreRead less
Locating Interference to GPS: Protecting the World's Aircraft Landing Systems. GRAS is an enormous initiative that is expected to generate billions of dollars in exports for Australia. The equipment developed in this project will protect the system from radio frequency interference. It thus protects these exports, and creates a new exportable product. By protecting this system, it makes air travel safer both in Australia and in the countries that buy this Australian technology.
High-Bandwidth Control and Advanced Dynamic Modelling for Unmanned Helicopters. Advanced control theory will be applied to enable precise control of unmanned helicopters in the presence of disturbances. This is critical for: operating unmanned helicopters among the buildings of urban environments, reconnaissance, investigating dangerous areas, pursuit of targets, and many other desirable capabilities for law enforcement and military purposes.

Advanced control theory will be applied to enable precise control of unmanned helicopters in the presence of disturbances. This is critical for: operating unmanned helicopters among the buildings of urban environments, reconnaissance, investigating dangerous areas, pursuit of targets, and many other desirable capabilities for law enforcement and military purposes. The ability of a small RUAV to launch and recover to a moving vessel would significantly enhance operational possibilities for border protection tasks and the Australian Defence Force. The research has direct application to other mechanical systems such as underwater vehicles, mobile robots, and precision control of agricultural vehicles, overhead cranes, and mining equipment.Read moreRead less
