RMIT UAS Research Team PhD candidate Nicola Kloet has had her work on acoustic signature measurement of small multi-rotor UAS published in the International Journal of Micro Air Vehicles.
The noise generated by these “drones” is seen as one of the barriers to their widespread implementation in populated environments. Nicola’s work, done as part of her final year project for her Bachelor’s degree, is the first step toward understanding and controlling this noise. Nicola is now continuing her studies as a PhD candidate, in which she is investigating human perception of UAS noise, and looking at methods by which noise can be reduced.
The paper is freely available online here.
RMIT UAS Research Team’s work on emulating avian orographic soaring in urban environments has been featured in Bioinspiration & Biomimetics Highlights of 2016, a collection which includes some of the very best and most influential research published in the journal over the last year.

The competitors from the AMAV contest after a successful day.
Unmanned Air Vehicles are being used for an ever-increasing range of tasks; goods delivery, information gathering and disaster relief. Members of RUASRT recently held the first Australian Micro Air Vehicles (AMAV) Competition in the basketball courts at RMIT’s Bundoora West campus. AMAV committee lead, Dr Abdulghani Mohamed said:
“It was a resounding success; the initiative provided students with a transformative experience through project-based learning integrated within existing engineering courses as the culmination of design-build-fly projects”.
Eleven teams navigated their multi-rotor machines through obstacles including payload delivery in the GPS-denied environment. All teams completed the majority of tasks and top-placed teams displayed some excellent autonomy, including reading QR codes on the obstacles, whilst being buffeted by wind gusts.
Competing student Rohan Gigacz enthused:
“The AMAV competition along with the UAS course allowed us to translate what we have learnt in the class room into a challenging real life application. The competition day was a great way to end the semester and I look forward to future AMAV competitions which look to be bigger and better!”

A big thanks to everyone who helped, especially: Dr Jennifer Palmer and DST Group for sponsorship.
Based on the success of the AMAV event, RMIT has been selected to host the IMAV 2018 competition in 2018, where competitors from all over the world compete and present their research, helping RMIT build capability, expertise, and international collaboration in this emerging field.

Members of RUASRT were on Network 10’s Scope on Saturday morning. Scope is a funny and informative children’s science show, aimed at kids ages 8-14, with sections presented by experts in their field. During the engineering-themed episode, Sam, David, and Ashim discussed the process for designing and building drones. In the video you can see the team working on electronics, explain important design considerations, and fly our favourite caged-drone, MARV.
Season 3, episode 119 is here, our section begins at 8:10. Enjoy!
RMIT graduate student and post RUASRT member Andrew Harrison has been working with CSIRO and Newmarket Gold on developing multi-rotor UAS capable of surveying the large voids produced as a result of underground mining. The ability to operate regardless of the complex ground terrain allows the system to survey regions of the void which would not possible by any other means. The data obtained by the UAS provides mining engineers with required information to make strategic decisions in the recovery of ore and expansion of mining operations. These processes can be conducted in a safer and more efficient manner than otherwise possible due to the use of the developed UAS technology.
21-May-16 RUASRT research into the development of safety case templates for remotely piloted aircraft has been used by Insitu Pacific Pty Ltd in support of its beyond visual line of sight operations in Australian airspace (http://lnkd.in/eZHspTG). An announcement of the successful BVLOS operations conducted by Insitu Pacific Ltd is available here.
The research, which was co-developed by Dr Reece Clothier (RMIT University), Mr Brendan Williams (Boeing Research & Technology – Australia) and Dr Neale Fulton, was published in Safety Science, and presented at the recent Australian Association for Unmanned Systems (AAUS), RPAS in Australian Skies Conference. The paper can be viewed here. The framework was also adapted by Nova Aerospace to support the safety case for RAAF Heron operations in North Queensland.
A great example of research having practical outcomes for the industry.
Members of RUASRT have formed the Australian Micro-Air-Vehicles (AMAV) organisation which will organise an annual competition to promote innovations for Unmanned Aerial Systems (UAS). The 2016 competition is open to RMIT staff and students but in future will open to all universities across Australia and internationally.
The AMAV competition involves two obstacle courses of varying degrees of difficulty aimed for undergraduate and postgraduate university level student contestants. The goal is to design a UAS to complete industry-relevant tasks such as obstacle avoidance and payload delivery, while dealing with real-world complications like wind gusts and lack of GPS signal.
For more information, or to enter the competition, see the website: http://amavs.org/
The RUASRT has had a large influx of interested undergraduate students in 2016 from a range of disciplines. PhD Student Sam Prudden provided two free tutorials totalling four hours to ensure that the new students can obtain a baseline knowledge of multi-rotor UAS (MUAS) and become active and productive members in the team.
The tutorials covered topics including applications and rules for MUAS, considerations for airframe design and configuration as well as details about propulsion, avionics, payload and communications systems.
These tutorials are the beginning of a new series run by post-graduate volunteers aimed to support both extra-curricular activities and coursework involving MUAS. Each tutorial was video recorded and they are available to RUASRT members.
RUASRT members Sam Prudden, David Purser and Ashim Panta recently filmed a segment about multi-rotor UAS for Network 10’s Scope TV program. Scope aims to provide fast, funny and informative science television for children aged 8-12 years.
The segment was titled “Drone Builders” and was filmed entirely in the RUASRT Lab at RMIT Bundoora East Campus. The hosts demonstrated the development phases for multi-rotor UAS, including eliciting customer requirements, conceptual and detailed design, manufacturing, testing and demonstration to the customer. The hosts were able to demonstrate the wide range of multi-rotor platforms utilised by RUASRT as well as providing examples of CAD models and carbon fibre moulds and materials used during the design and manufacturing processes. The hosts even wowed the film crew with some (safe) indoor FPV flying of a micro-quadcopter.
The segment was a complete success, being thoroughly enjoyable for both the RUASRT members and Network 10 film crew, and will air on Channel 11 in the near future.
RMIT UAS Researchers have continued their work to develop a remotely piloted aircraft (RPA), also commonly referred to as a drone, that can autonomously soar on updrafts. By doing this, the drone can save energy and extend its endurance. RMIT media have just released a new video explaining the project. See the news release and video on the project below:
