Picture the electric atmosphere of a World Cup final. The crowd roars, the score is tied, and a penalty shootout will decide it all. The referee turns to the video assistant referee (VAR) system, and the world holds its breath. But then, chaos erupts – a line on the field is off by mere centimeters, throwing the call into question and the game’s outcome hangs in balance.

This scenario highlights a rarely discussed flaw in modern sports: while athletes train with cutting-edge technology and stadiums undergo billion-dollar upgrades, the lines on the field are still painted the old-fashioned way. It’s surprising how labour-intensive this process is: in Hong Kong or Singapore, for instance, teams of workers can toil for hours under the sun, battling mosquito bites as well as the elements as they manually trace lines with chalk or paint dispensers. This outdated method is time-consuming and prone to human error. In an industry obsessed with precision, field maintenance remains stubbornly analog.

Precision meets purpose in redefining efficiency

Transforming this process is FJ Dynamics, a Hong Kong-incubated robotics startup that’s rewriting the rules of precision and efficiency. They are transforming the invisible, labor-intensive tasks that keep industries running—from sports fields to airport runways to construction sites—into seamless, high-tech operations. Established in 2017, it is on a mission to alleviate the burden of manual labour on a global scale by leveraging advanced smart automation and high-precision sensors.

FJ Dynamics has visited every sports ground in Hong Kong with its landscaping robot, the PaintMaster Pro, a smart robotic system designed to tackle field marking challenges. The robot uses advanced GPS technology to apply lines with maximum precision. Dual global navigation satellite system (GNSS) receivers ensure consistent accuracy across large areas, while optional laser guidance handles tricky spots near structures. The technology enables the robot to deliver precise specifications for a wide range of sports grounds, adapting to the unique requirements of each discipline — whether creating football pitches, rugby fields, or tennis courts.

The PaintMaster Pro doesn’t just bring 21st-century precision to maintenance practices. It’s also remarkably simple and cost-effective. The technology requires no specialised training. Just pour in the paint, turn on the machine, and press start. Anyone with a tablet can accomplish in 45 minutes what would take a crew four hours to do manually. Plus, it’s available at around half the price of comparable products thanks to its proximity to the Greater Bay Area’s extensive manufacturing resources.

“Innovation does not have to be expensive. The key is that it must be affordable and accessible so that everyone can use it,” says Kiki Zhang, CFO of FJ Dynamics.

The PaintMaster Pro is designed for versatility. Users can use a single robot for multiple functions by assembling different kits, including mowing and fertilisation spraying. Having found enthusiastic uptake in Hong Kong, it’s now enhancing major sports grounds across Europe, including Barcelona’s elite training facilities and premier rugby pitches in England and Germany, this robot is leaving its mark—literally—on the global stage.

“Home to a multitude of multinational companies, Hong Kong is an ideal launchpad for reaching global audiences. Once our products gain validation and recognition here, scaling the business overseas becomes significantly easier,” says Zhang.

Infrastructural precision saves lives

In daily life, the significance of precise markings extends beyond athletic fields. Modern infrastructure depends on carefully placed lines for optimal functionality, from bustling parking lots, sprawling warehouses to high-stakes airport runways, perfectly placed lines are critical for safety and efficiency.

FJ Dynamics’ recent collaboration with Hong Kong International Airport on runway markings highlights the role of high-precision sensor technology in infrastructure. With its advanced technology, the airport can now paint and maintain markings with exceptional accuracy and improved efficiency, significantly reducing manual labour while ensuring safety down to the millimeter.

Bridging the labour gap with 3D LiDAR

The same core technologies powering precise field markings are already revolutionising another sector facing labour shortages: construction development. Dominated by the older generation, the industry can be hard for younger workers to break into as experience is crucial. With a large number of workers aged over 60, the looming retirement of skilled laborers is likely to create a significant labour gap.

FJ Dynamics’ innovative robotics solutions are bridging this gap with 3D LiDAR scanners, enabling rapid digital modeling of job sites. Products like the FJD Trion S1 and Trion P1 leverage advanced LiDAR technology and SLAM (Simultaneous Localization and Mapping) algorithms to generate precise, real-time 3D environmental models. Users can effortlessly capture their surroundings and access live data directly on mobile devices. This technology allows for precise distance measurement and detailed spatial mapping, enabling the industry to assess high-risk or hard-to-reach environments, reduce accidents, and enhance operational efficiency. This has provided invaluable support for emergency services. Fire departments and police use them for efficient building inspections, while crime scene investigators employ them to create accurate, court-admissible 3D records, a significant improvement on traditional sketches and photographs.

Accelerated global expansion with HKSTP’s support

HKSTP’s vast customer and partner network connected FJ Dynamics with everyone from local civil service organisations to multinational enterprises, enabling the company to rapidly scale its business.

Since establishing its regional office in Hong Kong in 2021, FJ Dynamics has embarked on an accelerated global expansion journey, supported by the Hong Kong Science and Technology Parks Corporation (HKSTP), Asia’s no.1 emerging start-up ecosystem. HKSTP’s vast customer and partner network connected FJ Dynamics with everyone from local civil service organisations to multinational enterprises, enabling the company to rapidly scale its business. This aligns with HKSTP’s commitment to being an innovation and technology (I&T) powerhouse, offering entrepreneurs visionary insights and tangible support to drive technological advancement.

Building on this strong foundation, FJ Dynamics has established their expansion across APAC, Europe, the US, and Africa, while actively pursuing business and investment opportunities in the Middle East. For instance, a recent partnership with Saudi-based advanced positioning solutions provider Sintechs during the 8th edition of the Future Investment Initiative Institute, held in Riyadh, Saudi Arabia last October. It aims to enhance robotics technology and marketing capabilities across critical industries, further solidifying the company’s global footprint.

From lines we often overlook to spatial details invisible to the naked eye, each advancement in automated workflows contributes to shaping the future of work, paving the way for a more efficient, sustainable, and interconnected world. FJ Dynamics is committed to reshaping industries through accessible and affordable automation solutions, empowering labour-intensive and harsh-environment sectors to transform unnoticed — yet vital — manual work.
