SAUVC continued its successful streak this year with the 9th edition organized during 5-8 April 2024. This year’s event achieved a new milestone in terms of team registration and participation, solidifying its status as the largest SAUVC to date. Endorsed by the United Nations Decade of Ocean Sciences, this edition underscored the event’s alignment with the overarching goals of this global initiative, particularly addressing five out of its ten challenges. This endorsement also highlights the significant role played by IEEE OES within the framework of the Decade.

Notably, this edition held particular significance as it coincided with and was complemented by other OES events occurring in Singapore, namely the OES Summer School and the OCEANS 2024 Singapore conference, all within a week’s timeframe. This convergence provided an invaluable opportunity for student teams to engage in hands-on learning through the challenge while also benefiting from tutorial-style education at the school, technical sessions, panel discussions at the conference, and interactions with the oceanic engineering community at large. Furthermore, participants could explore potential networking and career opportunities offered by OES programs such as CNET (Career and Networking Tours) at OCEANS.

This plan to synergize the events worked out successfully. Up to 80% of the summer school attendees was comprised of SAUVC team students who stayed back for the school, and there was some cross-participation across the events.

SAUVC in numbers

This year saw:

79 teams registered for the event. These teams had to prequalify for participation by submitting a video of their AUV swimming underwater, with a requirement that the video should show it swimming for at least 15 seconds and demonstrating their AUV’s depth control.

  • 72 teams participated by submitting videos of their AUVs as part of pre-qualification requirements.
  • 43 teams were selected from the submitted videos to attend the event in Singapore. There was a clear jump in the quality of team videos this year as compared to previous years, and the judging team had a hard time shortlisting the teams, and strict quality criteria were used for filtering.
  • 37 of the selected teams made it into the event. Some teams could not make it due to non-receipt of a travel-visa on time, or technical or financial issues. This is a phenomenon observed in most events, as students in the region (especially South Asia) often develop their AUVs on tight budgets and do not necessarily find the funds to travel so far for the event. Nevertheless, despite the travel, visa and funding issues faced in the post-Covid era, it is impressive that so many teams made it and were able to participate.
  • 320 student participants made it to the event in total, from
  • 12 countries (India, Singapore, Indonesia, Malaysia, Turkey, Russia, Taiwan, Hong Kong, Saudi Arabia, Sri Lanka, Japan and Bangladesh, in decreasing order of participants). Notably, we had the first ever team from the middle East (Saudi Arabia) participating at the event, and the second-ever team from Bangladesh. Needless to say, both teams were elated to be here!
  • 1 High-school team (from Alana Science High school, Turkey) performed very well at the competition, and the fact that they achieved this at an early stage in their education made it even more exciting.
  • The representation of teams from across Asia was yet again extensive, and shows the value that SAUVC brings to this region.

The Challenge

SAUVC 2024 introduced two additional challenges this year as compared to previous year:

  • An underwater communication task, to encourage teams to think about this important technological problem that is necessary for boosting ocean exploration, and
  • A bonus round in the TCOMS Deep Ocean Basin facility in NUS, where teams had to deploy their vehicles in waves and currents generated in the facility, and pass through a

The remaining tasks in this edition mirrored those of the previous one, following a two-tiered structure comprising a qualification round and a final round. To secure qualification, the AUV had to navigate from the designated starting line through the qualification gate without surfacing, contacting the bottom or walls, or the gate itself. The top 21 teams, achieving the swiftest times in the qualification round, progressed to the final round. During this stage, AUVs garnered points by executing a range of challenges designed to assess their abilities in acoustic and visual navigation, positioning, actuation, communication, and robotic manipulation. The ensuing table outlines the various functional capabilities under examination and their corresponding tasks.

A red flare would be placed in front of the gate in the first task, which the teams were required to avoid, and hitting the red flare would incur the team’s run ending immediately. This was to make sure the tasks were more challenging this year, thus progressively upgrading the challenge.

Each task carried a certain number of points, depending on the challenge and the difficulty involved in performing it. There was also a timing bonus, and a bonus associated with weight and dimensions of the AUVs. Apart from this, the tasks were made more challenging through randomization of the position of the buckets, flare and gate and its orientation. A complete description of the tasks, static judging criteria and award of points are covered in the competition rule book available at https://sauvc.github.io/rulebook/.

SAUVC 2024 Award Winners

A notable improvement in this edition was that 21 teams qualified into the finals, which is the highest number to date. Hence, the competition in the finals was stiff. The winner of SAUVC 2024 was a returning champion from a previous edition (2014), Bumblebee Autonomous systems from the National University of Singapore. The top 5 teams in the finals were as follows:

  1. Bumblebee Autonomous systems, National University of Singapore
  2. Team Abyss from Bannari Amman Institute of Technology, India
  3. Mecatron from Nanyang Technological University, Singapore
  4. Team Hydronautics from Bauman Moscow State Technical University, Russia
  5. Team Alesta from Alana Science high school, Turkey.

In addition to the top 3 finalists, we also awarded the following:

  • Judges (Venu, Hari, Bharath, Rajat and Mandar) interacting with teams during the technical walkabout for judging the Innovation award and Engineering Quality award

    IEEE OES “innovation” award, which was constituted in 2019. This was judged by a technical panel consisting of 5 members. Innovation was defined as anything that is new/different and intentionally implemented for a specific stated purpose in SAUVC, with practically shown application. Based on the above criteria, the team Hydronautics from Bauman Moscow State Technical University was awarded the OES “most innovative engineering” award.

  • IEEE OES “Engineering quality” award, from the Singapore chapter. The award was for the most sound and robust engineering design, and was awarded to Team Pioneer from City University, Hong Kong.
  • Fastest team award, for the team that was fastest in the qualifier round. The team Alesta from Alana High School, Turkey, was awarded this prize, and it was also an encouragement for the young team. The award included two vouchers to attend the Breaking the Surface 2024 conference to be held in Croatia, allowing the teams to further their marine robotics training.

The bonus round was a specially celebrated feature of SAUVC 2024. It was conducted in TCOMS in the presence of waves and currents generated in the ocean facility artificially. It gave the top 5 teams in the finals a chance to try their vehicle in more challenging environments involving waves and currents. Though many of the teams prepared their vehicles, and some teams managed to get very close to the gate (but missed it due to technical issues, eg., https://fb.watch/rl1s-IKoFo/ ), only team Bumblebee from National University of Singapore managed to cross the gate in the bonus round with a superb performance from their vehicle (video here: https://fb.watch/rl1nY3-EtR/ ). This was managed in the very last run of the vehicle just before time ran out, providing some nail-biting moments and drama to the round. The competition in TCOMs also provided an opportunity for other student teams to visit the state-of-the-art facility and learn more about ocean-simulation infrastructure, thus adding an educational element to it.

Gala Dinner, Award Ceremony and Panel discussion

The event culminated with a gala dinner on April 8th, where the prize announcements took place. This occasion not only provided teams with an opportunity to celebrate their achievements but also facilitated a relaxed networking atmosphere where they could engage with one another and with organizers from the underwater engineering community, spanning academia, industry, and defense sectors. The ceremony was hosted at Ngee Ann Polytechnic, creating a spirited and dynamic evening that included the distribution of participation certificates and the announcement of winners, sparking moments of joy and celebration. Following this, participants engaged in extensive discussions that stretched late into the night.

Furthermore, the event featured a panel discussion on the Ocean Decade, titled ” Navigating the Blue Frontier: Innovations in Ocean Technologies and Autonomous Systems for addressing Ocean Decade Challenges,” featuring notable figures from the marine robotics and education sectors. This panel discussion will be elaborated upon in a separate article within this edition of the Beacon. Additionally, a video showcasing Schmidt Ocean Institute (SOI)’s research vessel Falkor Too and the OES Berths of Opportunity was presented. In addition to students and panelists representing various academic and industry entities such as SUT, Subnero, Fugro, National University of Singapore, and Singapore Polytechnic, notable attendees included the Deputy Director of Singapore Polytechnic and the CEO of TCOMS Singapore.

 Concluding Remarks

The participants of the bonus round with the organizers

SAUVC has been successfully organized in nine consecutive editions over the past decade, establishing itself as possibly the largest and most prominent autonomous underwater vehicle competition for students in Asia and Europe. It has garnered considerable interest within the student robotics community and has had a tangible impact on student learning and ocean education outcomes.

The committee has noted the emergence of at least three marine robotics-based startups that originated from teams participating in SAUVC. These include BeeX in Singapore, which stemmed from the Bumblebee team, BRACU originating from the Bangladesh-based BRACU Duburi team, and another startup based on Team Tiburon from the National Institute of Technology Rourkela, India. The latter team even gained exposure on the reality TV show “Shark Tank India,” where they garnered significant investor interest, attributing their success in part to their participation in SAUVC!

Previous SAUVC winners, such as Bumblebee and BRACU, have gone on to achieve success in other marine robotics competitions held in the USA, including RoboSub, showcasing how the learning experience at SAUVC has fostered the growth of these teams. Several teams in the current edition exhibited noticeable growth in both their AUVs and team structure, exemplified by Team Abyss from India, who were runners-up in this edition after securing the second runner-up position in SAUVC 2022.

SAUVC 2024 has established fruitful synergy with other IEEE OES events, including OCEANS 2024, the inaugural Summer School, CNET, and Breaking the Surface 2024. Various OES initiatives were also highlighted at the SAUVC gala dinner, including Berths of Opportunity and the AUV Symposium.

By not imposing a blanket registration fee for participation, SAUVC continues to attract significant participation each year. This no-registration fee policy aims to encourage novice teams to compete, with IEEE OES membership drives conducted as part of the registration process. The substantial representation in terms of participating countries, number of students, and diversity is deemed encouraging. Additionally, SAUVC prioritizes educational outreach, providing teams not only with a hands-on competition experience but also with valuable interactions with committee members and marine robotics experts who offer mentoring and guidance.
