TinyMobileRobots Terra Surveyor

A fully autonomous robotic plotter that integrates with GNSS to mark site layouts with millimetre precision. It allows civil engineers and road marking teams to set out entire sites or pitches up to ten times faster than traditional manual methods, operating with high reliability in rugged environments.

Rugged Off-Road Construction Layouts – Purpose-built with a tough chassis and 12-inch high-traction wheels to navigate unrefined landscapes, loose soil, and gravel embankments smoothly.
Universal Positioning Brand Compatibility – Integrates seamlessly with your existing survey-grade total stations or RTK GNSS receivers from major manufacturers like Leica, Trimble, and Topcon.
Automated High-Speed Pre-Marking – Executes high-precision stake-outs and road pre-stripping up to ten times faster than traditional on-foot manual layout teams.
Full-Shift Battery Endurance – Delivers up to eight hours of continuous autonomous field operation from a single weatherproofed battery charge to maximize jobsite uptime.

Full Description

For civil engineering projects and large-scale surfacing works, the TinySurveyor (Terra) removes the bottleneck of manual staking. By uploading a DXF file, the robot autonomously navigates the site, marking points, lines, and text directly onto the surface. This "fit-and-forget" solution ensures that road marking companies can complete days of work in a matter of hours, maintaining constant accuracy without the risk of human error. The Terra model is engineered for the rigours of the construction site, featuring big-wheel capability for navigating uneven ground and a versatile spray-can mounting system. Because it interfaces directly with your existing GNSS/RTK rovers, it fits seamlessly into your current workflow. Whether you are marking out piling locations or sports field boundaries, the TinySurveyor provides a high-speed, cost-effective alternative to traditional site mobilisation.

FAQs

Can it mark text and complex curves autonomously?

Yes. The TinySurveyor can mark points, straight lines, arcs, and even text directly from your CAD file. This allows road marking companies to label junctions or sports field marking companies to plot precise pitch boundaries without manual intervention.

What level of accuracy can I expect on site?

When used with a high-precision GNSS/RTK rover, the robot achieves millimetre accuracy. This level of precision is critical for civil engineering contractors tasked with high-stakes setting out for foundations or complex road layouts.

Is it compatible with my existing GPS equipment?

The robot is designed to be hardware-agnostic. It features a universal mounting plate that supports GNSS rovers from Leica, Topcon, Trimble, and more, allowing surfacing companies to use their own existing site infrastructure.

How fast is the robot compared to a manual two-person team?

The TinySurveyor can mark out a site up to ten times faster than a traditional team. For sports field marking companies, this means significantly reducing the time spent on-site and freeing up skilled staff for more complex analytical tasks.

What surfaces can the Terra model operate on?

The Terra version is specifically designed for varied terrain. While most effective on flat compacted soil, stone, or asphalt, its big-wheel design allows it to navigate the types of surfaces typically found on civil engineering and earthworks sites.

How long does the battery last for a full shift?

The robot features a hot-swappable battery system that typically provides 8 hours of continuous operation. This ensures that surfacing and road marking teams can complete a full day’s work without downtime.

How does the TinySurveyor compare to the HP SitePrint plotter?

The TinySurveyor is built for the rugged conditions of civil engineering sites, featuring larger wheels and higher ground clearance than the HP Plotter. It is designed to handle the dust and uneven surfaces common in surfacing and infrastructure projects.

Are there ongoing costs per metre marked, like with some competitors?

No. Unlike the HP SitePrint model, you do not have to pay for every metre used. Once you hire the TinySurveyor from us, you have unlimited marking capability within your hire period, making it a much more predictable and cost-effective choice for large road marking or sports field schemes.

Do you offer full setup and hire support?

Yes. We offer flexible hire packages and can assist with the initial software setup to ensure your CAD files are formatted correctly. Most customers opt for a familiarisation session with our Technicians upon their first hire. Our team offers ongoing remote support throughout your hire.
