“To see the Padang green and undiminished, with the SCC and the SRC, buildings of another era, guarding two ends of it, is to be reassured. It is a piece of Singapore I know, a reassuring sight of the familiar in a vastly changed city.” – Mr Lee Kuan Yew, Prime Minister of Singapore, 13 July 1986
Since 1905, the Singapore Recreation Club (SRC) has “guarded” one end of the Padang green, and promoted all forms of sports, recreation and social activities through an active calendar of events. Centrally located in the heart of the Central Business District of Singapore, the SRC’s facilities include a full size soccer field, a cricket pitch, two lawn tennis courts and a multi-purpose court, located right on the Padang green.
Attractive greenery - not just to humans, but to mosquitoes too

While the beauty of the surrounding architecture and parks makes the SRC ideal for hosting high-profile sporting events, its proximity to nature and the outdoors also makes the SRC attractive to mosquitoes.
The lobby area opens to the outdoor passenger drop-off point, making it easy for mosquitoes to enter the clubhouse. In addition, the semi-outdoor and alfresco dining areas such as the Connaught Terrace and B@Campo are also areas of concern. Being open to the Padang green, there are unavoidably more mosquitoes as compared to indoor areas like the nearby Esplanade, or the surrounding malls and office buildings. Indeed, the club members and SRC staff who frequent these areas report getting bitten by mosquitoes more often.
In an effort to protect their club members and staff from the potential risk of dengue transmission, the SRC collaborated with us during our latest Dragonfly Trial Deployment to test out the performance of Dragonfly, the world's first mosquito-control robot.
How does Dragonfly work?
Figure 2: Dragonfly at the SRC
Dragonfly is the world's first autonomous mosquito trap and kill robot. Equipped with a full suite of high performance mosquito control features, our robots offer effective protection against mosquito bites, risk of dengue and other diseases.
The robot attracts mosquitoes based on an effective combination of:
- Visual cues (High-contrast stripes, UV light)
- Olfactory cues (lure)
- Fan (Passive lure)
In addition to the visual and olfactory cues, the motion of the robot further increases the robot’s attractiveness to mosquitoes; studies have shown that mosquitoes are attracted to moving targets more than stationary targets.
In addition, a fan acts as a passive trap to suck mosquitoes that happen to be near the robot into an enclosed chamber, where they will be caught on an additional glue trap.

Deployment objectives - Indoor operation
Our deployment team brought Dragonfly to the SRC for a deployment trial that was held over four days in August 2021. One of the main objectives of this trial deployment was to verify if Dragonfly could patrol around the indoor lobby area of the SRC without any assistance or human intervention. In addition, the team needed to ensure that Dragonfly could navigate autonomously to different way points without colliding into any staff or the desks and counters in the lobby.
The trial will also be used as a preliminary benchmark for the average number of mosquitoes that Dragonfly may catch per day in an indoor/semi-outdoor environment.
Promising Results from the Trial
Dragonfly successfully mapped the indoor lobby area on the morning of the first day (see Figure 3), and the trial proceeded smoothly.

On the third day, Dragonfly was brought up to the St. Andrew Terrace, a semi-outdoor area located on the third floor of the clubhouse (circled in red in Figure 3), to test its performance for semi-outdoor operation.
The robot caught a total of 18 female mosquitoes, which are capable of spreading diseases over four days (See Table 1 for more details).

The favourable results from the trial show that Dragonfly is a good solution for both indoor and semi-outdoor environments. In particular, Dragonfly is able to augment current dengue-control measures for indoor areas with air-conditioning, where the use of fogging as a mosquito-control solution would be highly undesirable and unsuitable.
We are pleased that the trial was a success, and look forward to working with SRC and other clubs and societies in the future.
