SLAM for Shiploader Anti-collision
As system automation is being applied to increasingly complex tasks, autonomous systems are now operating in dynamic and non-predictable environments. This shift in the domain of operation requires autonomous systems to actively perceive the world in which they operate and make decision based on the information they gather.
In this project, the Autonomous Systems Research Centre engaged with a local industry partner (MRA) to enable perception of coal vessels using a variety of on-board sensor information. Using a mixture of Bayesian and machine learning techniques, the shiploader systems were enabled to autonomously detect points of interest, such as hatches, on coal ships.
A nanopositioning device can move an object in one, two, three, or more dimensions. A typical range in each dimension is 10um to 200um with a resolution of 1nm, or 5 atoms of Carbon.
Nanopositioning devices are widely applied in microscopy, optics, semiconductor manufacturing and life sciences. This project is developing new nanopositioning devices, sensors, amplifiers, and control systems to increase the bandwidth and precision of piezoelectric nanopositioning stages.
The Precision Mechatronics Lab has developed several high-speed and highly precise nanopositioners which are being used in scientific instruments such as the atomic force microscope.
Microelectromechanical Systems (MEMS)
This work motivates a class of probes based on microelectromechanical system (MEMS) design with integrated actuators and sensors optimized for multifrequency operation. Specifically, integrated piezoelectric transduction schemes enable the miniaturization of the Atomic Force Microscope towards a cost-effective single-chip device with nanoscale precision in a much smaller form factor than that of conventional macroscale instruments.
The Precision Mechatronics Lab has developed several active microcantilever designs which are being used in scientific instruments such as the atomic force microscope. Significant collaborative research efforts also went towards developing a single-chip atomic force microscope.
Stockpile Profile Mapping with MRA and PWCS
Ports and mines use large stockpiles of bulk material as a storage buffer. The process of adding new material to a stockpile is called stacking, and the removal of material is called reclaiming. Stacking and reclaiming are typically performed by large machines that interact with the stockpile and these machines form part of the critical path and directly effect port efficiency. To automate and optimise stacking and reclaiming it is vital that the machines are aware of the stockpile profile, especially since the profile can change over time due to changing environmental conditions.
To this end, the Autonomous Systems Research Centre engaged with local partner MRA and to deliver real-time modelling of stockpiles based on a fusion of mass-flow principles and Radar and Laser scanning sensors. This approach is proving to be very successful and is currently undergoing commercialisation. This work is in collaboration with Port Waratah Coal Services and Abbot Point Coal Terminal.
