Members of the Providence Section and
OE22 Chapter gathered for the technical talk in
“The Presidents Room.”

On May 2, 2019, members of the IEEE Providence Section and the OE22 Chapter gathered at White’s Restaurant in Westport, MA for a joint social half-hour and dinner before attentively enjoying the technical presentation “Free Wind or Bought Wind?: Shifting Power Generation at Sea over Two Centuries.” The lecturer, author John Laurence Busch, is an independent historian who focuses upon the interaction between humanity and technology, specializing in 1st and early 2nd generation steam-powered vessels. His book on the first steamship in history, entitled “STEAM COFFIN: Captain Moses Rogers and The Steamship Savannah Break the Barrier,” has received positive reviews from over two dozen periodicals and academic journals in the United States, Canada, the United Kingdom and Australia. For more information, visit www.steamcoffin.com.


Author John Laurence Busch describing the evolution of power at sea from sail to steam over the last two centuries.

In his presentation, Mr. Busch chronicled the long evolution from natural power to artificial power at sea, breaking down the development from both a “steamboat” and “steamship” perspective.

At the beginning of the 19th century, the human race remained—practically speaking—in the same place it had been for millennia. Humans were beholden to the omnipotence of Nature, meaning the only way to move themselves from one place to another was by natural means. On land, this meant foot, hoof, or wheel, all of which were powered by animals; on water, it was either human-driven paddles or wind-driven sails. There was little reason to believe human locomotion would ever be any different.

Then, in 1807, an American named Robert Fulton built and ran the first commercially successful “steamboat” in history. In so doing, Fulton achieved something epically important: he proved that humans could create an artificial power to alter where they were and when they were there to practical effect. No other invention had achieved such a thing, and accordingly, steamboats may be considered the first “high technology” in history.

But the transition from sail energy to steam energy was not immediate, or easy. Nor was the transition from steamboats running on rivers, lakes and bays to steamships capable of making trans-ocean voyages.

The author then analyzed modern-day efforts to re-introduce various forms of natural power to modern, artificially-powered commercial vessels, and the rationale for doing so. This included an analysis of the types of fuel used to power the “new mode of transport,” as well as efforts by the “old mode of transport” (i.e., sail) to compete, which led to a very long battle for supremacy at sea.

Technologies touched on included recent design proposals such as high profile sail-like hull shapes, and arrays of deck-mounted sail-like solar panel arrays. One particularly promising technology, which has seen a recent revival, is the Flettner rotor. A Flettner rotor is a smooth cylinder with disc end plates which is spun along its long axis and, as air passes at right angles across it, the Magnus effect causes an aerodynamic force to be generated in the direction perpendicular to both the long axis and the direction of airflow. First introduced on an experimental rotor ship in 1922, this technology is again being considered as a means to reduce both fuel costs and carbon emissions.

Finally, the possibility that other high technologies will revert to some or a greater share of natural power generation was explored, and how studying the initial development of these inventions might help show the way forward.

Singapore Chapter—A Workshop on Autonomous Marine Systems
Reported by Bharath Kalyan, Hari Vishnu, Venugopalan Pallayil & Ahmed Mahmood

The IEEE OES Singapore chapter organized its third annual workshop on Autonomous Marine Systems on 11 March, 2019, at the Singapore Polytechnic, following the 7th edition of the Singapore AUV Challenge (SAUVC) event. The workshop idea was started in 2017 with an objective of complementing the hands-on experience that the students had gathered through the competition, with further insights from experts in the field. The workshop was aimed at motivating the students to continue to pursue the field of autonomous marine technology and enhance their knowledge through a sharing and learning session. This year’s guest speakers included a good mix of experts from land and marine robotics and also representation from academia, industry, research institutions as well as student competition organisers and participants. This event also facilitated excellent networking amongst the AUV experts and the attendees, which included both student team members and external attendees. The talks were followed by a panel discussion. The focus of the panel discussion revolved around questions posed by the student attendees, which was collated via an online poll taken prior to the workshop.

Guest speakers in action.

The guest speakers included Dr. Gabriele Ferri, Assoc Prof Marcelo H. Ang, Jr, Ms. Kelly Cooper, Mr. Richard Mills, Mr. William J. Kirkwood and student Liu Ren Jie. Gabriele Ferri is a Research Scientist at the NATO’s Centre for Maritime Research & Experimentation (CMRE). He spoke on autonomous robotics networks for underwater surveillance. In this talk, he compared the performance of autonomous vehicles for surveillance applications when operated in a networked configuration as compared to a single AUV configuration. He also discussed the potential and challenges of such a configuration. Marcelo H. Ang, Jr is an Associate Professor in the Department of Mechanical Engineering of National University of Singapore, delivered the second talk. He spoke on the impact of robotics in our daily lives and delved on the emerging applications in human robot interactions in unstructured environments. He also touched up on the state-of-the-art developments in sensing and intelligence to accelerate robotics revolution. Kelly Cooper is a Program Officer at the Office of Naval Research (ONR). She has been responsible for initiating a variety of student robotics competitions for the U.S. Navy, including the Maritime RobotX Challenge, RoboBoat and SeaPerch. In the post-lunch session, Kelly spoke about using a simulation environment (virtual competition) to enhance the performance of autonomous vehicles. Her talk was also an introduction to the Virtual RobotX competition, a new initiative by ONR. Richard Mills, who is the Director of Marine Robotics Sales with Kongsberg Maritime, spoke about improving productivity in deep water AUV surveys. He also discussed various sensing technologies that have gone into the HUGIN AUV including synthetic aperture sonar, multibeam echo-sounder, sub-bottom profiler, camera, laser, magnetometer and methane sensors. William J. Kirkwood is a senior R&D Engineer at Monterey Bay Aquarium Research Institute (MBARI). He spoke about plastics in the food web, and how it was a problem that re­­quired future technology solutions. Bill discussed about microplastics and their impact on our oceans and in-turn, on humans. His talk also focused on advanced instrumentation and robotics that are able to identify these plastics and trace them to their source. Finally, we had one talk from a student, Liu Ren Jie, a 4th year Electrical Engineering student from the National University of Singapore and also is the technical lead of the Bumblebee team. He spoke passionately about team Bumblebee and how they managed the challenges of sustaining and growing a student-run team and covered topics ranging from knowledge management to competition preparations. The video recordings of these talks can be viewed at the following link:

In the afternoon session of the workshop, a panel discussion by the experts on autonomous marine systems and competitions and careers in underwater technologies was organized. The questions taken up for discussion by the panelists, were collected via a student participant’s poll, the Pigeonhole App. The top 10 questions polled by the audience via an online poll were taken up at the discussion. The questions that were posed to the panel were:

  1. What career opportunities are available in underwater robotics?
  2. Tips to “debug” underwater robots during development?
  3. What role does ROS play in the development of underwater robotics?
  4. Any tips on how to build low-cost underwater robots?
  5. How to tackle challenges like Localization, navigation & communications?
  6. How does AUV research in Asia compare to Europe and North America?
  7. How can we better promote AUV activities in secondary schools?
  8. How can we harvest energy from the ocean for use by underwater robots?
  9. How to use underwater tech to solve ocean pollution problems?
  10. What is the role of swarm technology in underwater robotics?
Panellists intently listening to questions put forward by the moderator.

The panel was moderated by Mandar Chitre, Associate Professor at National University of Singapore. Fausto Ferreira, a Research Scientist from at the NATO’s Centre for Maritime Research & Experimentation (CMRE) joined as a panelist along with William Kirkwood, Richard Mills and Kelly Cooper. All the questions posed via the poll were pertinent to ­student involvement in AUV technologies and competitions. They included queries on the future of AUVs, the benefit and career opportunities for students in this field, how to tackle some commonly faced issues in constructing AUVs and questions on real-world applications of AUVs. The questions saw some very animated involvement from the panel members, who all chipped in to give a well-rounded take on the students’ queries. Overall, the workshop turned out to be a useful learning experience for all the participants.

Apart from this workshop on the side-lines of SAUVC (the report is in this issue), we had two public engagement sessions which were conducted at Singapore Polytechnic on March 9th, 2019:

Tutorial on introduction to underwater robotics.

Singapore Robot Operating System (ROS) Meetup organized a session on practitioner’s guide to autonomous vehicle development. Dr. Benjamin Ma discussed about an on-going self-driving car project and provided an overview of future of autonomous vehicles.

The SAUVC LOC organized a tutorial session on “Introduction to underwater robotics.” The tutorial was led by Rajat Mishra, a graduate research student with National University of Singapore. At this session, we had a large representation from ANZA scouts with students in the age group of 8–17 years. This event was very well-received and we are planning on expanding the public engagement exercise for the next edition of SAUVC.

These workshops were very beneficial for the students, specifically for the teams who participated in the SAUVC event. This was evident from the excellent feedback we obtained through a survey. We propose to continue the organization of similar workshops alongside future SAUVC events. We would like to acknowledge our speakers for their inspirational talks and supporting this event.
