Meet our E.P.I.C. Researcher, Phuong Tran

Phuong Tran is a PhD researcher based at the Queensland University of Technology and her project is part of the Collaborative Robots and Humans’ Work project, which is part of the Human-Robot Workforce program at the Australian Cobotics Centre. We interviewed Phuong recently to find out more about why she does what she does.

  • Tell us a bit about yourself and your research with the Centre? Include the long-term impact of what you are doing.

I completed my Master of Business in 2018 and Master of Philosophy (MPhil) in early 2023 at Queensland University of Technology (QUT). My MPhil thesis focused on organisational justice on digital labour platforms. I worked as a sessional academic at QUT and Griffith University between 2019-2023, and as a Research Assistant in various QUT research projects before commencing my PhD in 2023.

My PhD research project is based at QUT and part of the CSIRO’s Collaborative Intelligence (CINTEL) Future Science Platform. My research seeks to understand the work design implications of working with collaborative robots (cobots) in manufacturing. Understanding the effect of cobot usage on work design characteristics is crucial for assessing their effect on workers’ job satisfaction and turnover intention. This understanding is important in the context of manufacturing sector, which is currently experiencing labour shortages and challenges attracting and retaining talent. At the same time, manufacturers are turning to advanced technologies, such as cobots, to increase production competitiveness. Therefore, it is essential to comprehend the impact of cobots on job satisfaction and turnover intention to effectively manage the integration of cobots into the workplace. This ensures that the benefits of cobot usage for organisations are maximised while minimising potential negative effects on workers.

Why did you decide to be a part of the Australian Cobotics Centre?

I decided to join the Australian Cobotics Centre (ACC) because it offers a unique opportunity to engage in interdisciplinary research within a large collaborative community. The ACC brings together researchers from various fields such as engineering, design, and management, and fosters industry engagement, to address complex challenges and changes associated with the integration of collaborative robots (cobots) within the Australian manufacturing. Additionally, my past research focused on digital platform workers’ fairness perceptions, and at the ACC, I can continue exploring the impacts of technology on people and the nature of work.

  • What project are you most proud of throughout your career and why?

The project I am most proud of throughout my career is my current PhD research. What makes this project particularly meaningful to me is the personal and professional journey it represents. Balancing the demands of a PhD research project while being a first-time mom has been challenging yet rewarding.  It has provided me with opportunities to develop myself both personally and professionally, teaching me resilience, time management, and the importance of support systems. This experience has not only enriched my skills but also deepened my appreciation for the impact of work-life balance on job satisfaction, a key aspect of my research.

  • What do you hope the long-term impact of your work will be?

I hope my work will provide valuable insights to inform organizations on the design and implementation of cobots, enabling them to optimise their cobot usage and/or address associated work design issues. I aspire for my research to inform policies and practices that promote positive and sustainable work environments. I aim for the findings from my research to support the development of strategies to create better-designed work environments, improve job quality, and therefore, enhance overall health and wellbeing outcomes for people.

I also hope the long-term impact of my work will extend to society at large. I would like for it to inform the creation of work opportunities for individuals who might not otherwise have access to them, and thereby contributing to greater social inclusion and independence.

  • Aside from your research, what topic could you give an hour-long presentation on with little to no preparation?

I would find it incredibly difficult to talk about anything for an hour without proper preparation. However, I imagine my one-hour long presentation would be titled: “The Art of Surviving Sleep Deprivation: Tips and Tricks from a First-Time Mom”.
Topics I might discuss include:

  • The science of baby sleep cycles (or why your baby thinks 3AM is a good time for karaoke)
  • Decoding baby talk: understanding the difference between “I’m hungry.”, and “I just scream for fun”.

ARTICLE: From Lab to Market (Part II): Bridging the Gap – Solutions for Effective Industry-Academic Collaboration

In today’s rapidly evolving technological landscape, the synergy between academic research and industrial innovation has never been more critical. Yet, as we explored in our previous article, significant barriers often hinder effective collaboration between these two sectors. From misaligned incentives to communication challenges, the road to fruitful partnerships is fraught with obstacles. However, where there are challenges, there are also opportunities for transformative solutions. In this article we will investigate how we can overcome these barriers between academic-industry collaborations and foster more productive collaborations? Here are some strategies I believe could make a significant difference:

1. Educational Outreach

  • Host Workshops and Seminars: Organize events that showcase research capabilities and potential benefits to industry partners. These can help demystify the research process and highlight its value.
  • Develop Industry-Focused Communication: Create materials that explain research in terms of business benefits, ROI, and practical applications.
  • Utilize social media: Leverage platforms like LinkedIn to share success stories, insights, and opportunities for collaboration.

2. Flexible Collaboration Models

  • Short-Term Projects: Offer opportunities for smaller, shorter-term collaborations that can serve as ‘proof of concept’ for more extensive partnerships.
  • Tiered Partnership Options: Develop a range of partnership models to suit different company sizes, budgets, and comfort levels with research collaboration.
  • Shared Resource Models: Create systems where multiple industry partners can share the costs and benefits of research initiatives.

3. Build Trust and Understanding

  • Industry Internships for Researchers: Encourage academic researchers to spend time in industry settings to better understand business needs and processes.
  • Academic Sabbaticals for Industry Professionals: Invite industry professionals to spend time in academic settings, fostering better understanding and communication.
  • Joint Advisory Boards: Establish boards with both academic and industry representation to guide research directions and collaboration strategies.

4. Address Financial Concerns

  • Highlight Long-Term ROI: Develop case studies and financial models that demonstrate the long-term return on investment for research collaborations.
  • Explore Public-Private Partnerships: Leverage government funding and initiatives designed to promote industry-academic collaborations.
  • Transparent Cost Structures: Develop clear, understandable cost structures for different types of collaborations to help businesses budget effectively.

5. Streamline Processes

  • Simplify Administrative Procedures: Work on streamlining the often-complex administrative processes involved in setting up research collaborations.
  • Dedicated Liaison Officers: Appoint individuals specifically tasked with facilitating and managing industry-academic partnerships.
  • Clear IP Agreements: Develop straightforward intellectual property agreements that protect both academic and industry interests.

The Path Forward

The future of innovation lies in the synergy between academia and industry. By working together, we can drive progress, enhance productivity, and tackle real-world challenges more effectively. It’s a journey that requires effort, understanding, and adaptability from both sides, but the potential rewards are immense.

As we move forward, I’m eager to hear from both my academic colleagues and industry professionals:

  • What challenges have you faced in establishing or maintaining industry-research collaborations?
  • What successful strategies have you employed to overcome these barriers?
  • How do you envision the future of industry-academic partnerships in your field?

As we explore these solutions, we’ll highlight the valuable contributions of organizations like the Australian Cobotics Centre. This pioneering training institution has been at the forefront of addressing the barriers between academia and industry, particularly in the field of collaborative robotics. Through its unique model of industry-led research, the Centre has been instrumental in developing practical solutions that not only advance academic knowledge but also address real-world industrial challenges.

ARTICLE: Accepted Papers for the IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS)

Australian Cobotics Centre researchers have two papers accepted for publication at the upcoming IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) 2024 in Abu Dhabi. IROS is one of the largest and most important robotics research conferences in the world, attracting researchers, academics, and industry professionals from around the globe.

Postdoctoral Research Fellow, Dr Fouad Sukkar gave is a brief summary of two of the papers appearing at the conference in October this year.

Constrained Bootstrapped Learning for Few-Shot Robot Skill Adaptation, by Nadimul Haque, Fouad (Fred) Sukkar, Lukas Tanz, Marc Carmichael, Teresa Vidal Calleja, proposes a new method for teaching robot skills via demonstration. Often this is a cumbersome and time-consuming process since a human operator must provide a demonstration for every new task. Furthermore, there will inevitably be some discrepancies between how the demonstrator carries out the task versus the robot, for example, due to localisation errors, that need to be corrected for in order for the skill to be successfully transferred. This paper tackles these two problems by proposing a learning method that facilitates fast skill adoption to new tasks that have not been seen by the robot. We do so by training a reinforcement learning (RL) policy across a diverse set of scenarios in simulation offline and then use a sensor feedback mechanism to quickly refine the learnt policy to a new scenario with the real robot online. Importantly, to make offline learning tractable we utilise Hausdorff Approximation Planner (HAP) to constrain RL exploration to promising regions of the workspace. Experiments showcase our method achieving an average success rate of 90% across various complex manipulation tasks compared to state-of-the-art which only achieved 56%.

Coordinated Multi-arm 3D Printing using Reeb Decomposition, by Jayant Kumar , Fouad (Fred) Sukkar, Mickey Clemon, Ramgopal Mettu, proposes a framework for utilising multiple robot arms to collaboratively 3D print objects. For robots to do this efficiently and minimise downtime while printing, they must have the flexibility to work closely together in a shared workspace. However, this dramatically increases problem complexity since there is a need to coordinate the arms so they do not collide with each other or the partially printed object. This is in addition to the planning problem of effectively allocating parts of the object to each robot while respecting the physical dependencies of the print, for example an arm can’t start extruding a contour until all the contours below it are printed first. All these factors make effective coordination a very computationally hard problem and we show that with bad coordination you can end up with even worse utilisation than if a single arm had carried out the same print! In this work we address this by performing a Reeb decomposition of the object model which partitions the model into smaller, geometrically distinct components. This drastically reduces the search space over feasible toolpaths, thus allowing us to plan highly effective allocations to each arm using a tree search-based method. For producing fast collision avoiding motions we utilise Hausdorff Approximation Planner (HAP). Our experimental setup consists of two robot arms with pellet extruders mounted on their end effectors. We evaluate our framework on 14 different objects and show that our method achieves up to a mean utilisation improvement of 132% over benchmark methods.
