Heavsty R1 Pre-marking Robot Deployed in Overseas Projects: Satellite Positioning Replaces Manual Line Marking, Ushering in a New Era of Digitalization in Road Marking Construction

Manual line marking is inefficient, varies in accuracy from person to person, and poses significant safety hazards for workers operating in traffic. The Heavsty R1 pre-marking robot, with its dual-antenna satellite positioning and automatic marking, has achieved precise pre-marking in overseas highway projects, replacing hours of layout in a single pass, thus facilitating the digital upgrade of road marking construction.

At a highway reconstruction and expansion site overseas, after the operator confirms the marking parameters on a mobile terminal, a yellow-bodied, dual-antenna, four-wheel off-road chassis pre-marking robot automatically moves along the lane, compressing the pre-marking process that originally required several workers bending over and manually marking lines for hours into a single, automated pass. This is a scene of the Heavsty R1 pre-marking robot in operation at an overseas project site—the first step in road marking construction is being redefined by "satellite positioning + intelligent marking."

Industry Pain Points: Why Pre-marking is "Indispensable"? Pre-marking is the first step in road marking construction, directly determining the positional accuracy of the entire marking system. However, traditional manual layout methods face three major challenges:

Efficiency Pain: Manual line pulling and marking rely on skilled workers. Complex line types and nighttime construction significantly increase time consumption, often making the layout process a hidden bottleneck in the project schedule.

Accuracy Pain: Layout accuracy varies from person to person and fluctuates due to fatigue. Once the baseline deviates, the subsequent marking machine will have to rework the entire line—the rework cost far exceeds the savings from layout.

Safety Pain: Workers walking on open roads, competing with traffic, pose one of the most prominent personal safety hazards on construction sites.

Heavy Solution: R1 Pre-marking Robot

The R1 uses "satellite positioning + automatic marking" to replace manual layout, providing a precise, efficient, and safe pre-marking solution for road construction and maintenance projects.

At overseas project sites (high slopes near cliffs and sections with guardrails), R1 completed continuous pre-marking operations. These complex terrains and congested traffic sections represent precisely the most difficult and dangerous scenarios for manual surveying. Thanks to its stable satellite positioning and autonomous driving capabilities, R1 maintained continuous operation on slopes and winding roads, providing a clear construction benchmark for subsequent line marking units—completing in a single pass what previously took hours of manual surveying. This allowed the intelligent combination of "pre-marking first, then mechanical marking" to be truly implemented on overseas construction sites.

Core competencies	Technical Highlights	Customer Value
Dual-antenna GPS/GNSS positioning	Dual satellite antennas receive positioning references, and the algorithm generates line parameters in real time after front-end data acquisition.	Accurate layout, controllable alignment, and stable positioning under complex road conditions.
Automatic pre-marking	The marking parameters can be confirmed with one click on a mobile terminal, and the robot will automatically move and draw the markings.	Replaces manual line marking, completing hours of layout in one go.
Four-wheel off-road chassis	Wide-base, deep-tread tires, high ground clearance	Adaptable to complex working conditions on construction sites such as soil, gravel, and asphalt.
Dual material boxes + orange warning light	Pre-marking materials are supplied continuously; warning lights clearly indicate road work.	Reduce supply frequency and ensure operational safety and compliance.

Frequently Asked Questions (FAQ)

Q1: What are the advantages of R1 over manual line drawing?

Efficiency, accuracy, and safety three points: one automatic pass replaces manual layout for several hours; The accuracy of satellite positioning and layout does not fluctuate with fatigue; The homework personnel do not need to enter open traffic sections, which significantly reduces personal risks.

Q2: How many people are needed to operate R1?

One person is sufficient. The operator confirms the marking parameters through the mobile terminal and starts the task. The robot moves autonomously and draws automatically, without the need for multiple people to cooperate throughout the process.

Q3: How to connect with the marking machine after the pre marking is completed?

Pre marking is the construction benchmark. The marking unit can operate along the reference line marked by R1. Heavsty can provide a combination delivery of "pre marking robot R1+ride on marking machine", seamlessly connecting the entire process of layout and drawing.

Q4: What road surfaces and working conditions is R1 suitable for?

Both asphalt and concrete pavements are suitable for operation; The four-wheel off-road chassis and wide base tires enable it to pass through unformed roadbeds such as soil and gravel, making it suitable for construction and expansion projects with alternating working conditions.
