The application of Topcon TinySurveyor automatic marking Robot in Highway Marking

01. Traditional construction

The first step

The marking personnel mark the points on the road surface at intervals of 10m to 30m along the longitudinal direction of the road, indicating the distance between the edge of the marking line and the curbstone (or the center line of the road) as designed. At bends, the distance needs to be correspondingly densified.

Step Two

Use a flexible rope to connect each point and draw a smooth curve or straight line (not all points are on the line) as the working line for setting up the water line.

Step Three

Use water-soluble and environmentally friendly civil interior wall coatings to lay out along the line and complete the calibration of water lines. By applying the principle of parallel lines (the width of the driving lane), multiple water lines can be drawn.

Traditional line tracing along a rope

The traditional construction methods have the following disadvantages

It is necessary to have experienced technicians who are very familiar with the design principles of marking lines and can operate various measuring equipment proficiently.

At least 3 to 4 personnel are needed on site. There are many places that need to be marked, such as the edge lines, center lines, shoulders and sidewalks of the road. The work is simple and repetitive, and the labor intensity is high.

This industry is facing severe challenges in terms of talent reserves, and the problem of insufficient injection of new blood is particularly prominent.

After road maintenance is completed, road marking requires traffic control or even partial closure, which incurs high control costs and poses a significant safety risk to on-site personnel.

Due to the accumulation of errors from multiple aspects, the main technical indicators of manual marking lines are difficult to guarantee, and the quality of the results is poor.

02. Robot construction

The TinySurveyor automatic marking robot from Topkong is an innovative product of epoch-making significance in the road marking industry. It is a brand-new technical form formed by mechanical control combined with GNSS or total station positioning. With outstanding performance, unique functions and a brand-new user experience, it has completely changed users' perception and demand for industry products.

Just bring the BIM design drawings to the road marking locations and send them to the TinySurveyor automatic marking robot. The robot will drive automatically and draw various complex straight lines, curves, text, dotted lines and other very precise line types on the road.

As the world's fastest automatic marking robot, it can bring you a safer and more efficient way of working.

According to different usage scenarios, it is divided into the following two types:

Plotter

"Highway type"

Designed for marking on roads or flat surfaces

2. It has an active obstacle avoidance function and provides more safety configurations

3. It has more connection options

Terra

"Off-road type

(All-rounder

Designed for marking work on complex surfaces

2. Robots for multiple purposes such as layout, setting out, and measurement

2. Specific parameters

Typical accuracy: 1-2 centimeters.

2) Emergency shutdown: There are two types of emergency shutdowns: manual and automatic. Operators can stop work in any emergency situation.

3) TinySurveyor uses simple designs to enhance efficiency. The robot uses a three-wheel configuration and can navigate and turn easily. Two large motors provide reliable power, allowing for free travel on the maximum designed slope of the road.

4) The overall weight is only about 20 kilograms, and this robot can be easily loaded onto the trunk of a car and transported from one location to another.

5) 8-hour battery: TinySurveyor can complete a whole day's work on a single charge without the need for rest.

6) Signal light: When the robot is working, the operator can see its instant communication.

7) Marking method: Use any self-spray paint can or line marking can to mark points and lines. Laser pointer marking can also be adopted.

8) Data communication: The Bluetooth function ensures that TinySurveyor can respond within seconds.

9) Guided positioning method: The robot can use a high-precision GNSS receiver or a total station to receive real-time location information.

3. Advantage Introduction

The adoption of the TinySurveyor automatic marking robot waterline layout construction method from Topkon can ensure the lateral deviation of the marking lines, reduce the impact of the rainy season on the marking period, lower the labor intensity of cleaning work, reduce the number of construction personnel (one person can complete the waterline calibration operation), improve work efficiency, and guarantee construction quality.

High efficiency

It is up to 10 times more efficient than manual labor

2. 4km/h, 8 hours of range

3. Reduce personnel and be able to work at night

High quality

1. 1-2cm accuracy

2. Draw complex curves

3. Good repeatability

Safer

1. People do not need to be in the traffic flow

2. Work easily while sitting in the car

3. Emergency stop button

4. Automatic Obstacle Avoidance (Plotter
