Topsky RXR-C11 (RXR-C11)

Ground penetrating radar reveals what lies beneath a road surface or a tunnel lining, yet the survey itself has long relied on someone walking the line. That person pushes an antenna at a steady pace through traffic management, standing water or the dust of a tunnel bore. The Topsky RXR-C11 (RXR-C11) changes who does the walking. It is a lithium battery powered, all-terrain robot that carries ground penetrating radar and a distance measuring wheel. The operator drives it by wireless remote control from a safe distance, while the robot holds the survey line and the radar records what is underneath.

Robots Europa, based in Dublin, supplies the RXR-C11 to survey contractors, infrastructure owners and inspection service providers across the European Union and the DACH region. Robots Europa prepares each quotation, arranges delivery to the project site or office, and remains your point of contact for technical questions and support once the robot is in service.

Background

Topsky and its ground robot range

Topsky builds unmanned ground vehicles for demanding field work. Its range on the Robots Europa network includes firefighting and scouting robots, explosion-proof platforms and wheeled robot chassis. The RXR-C11 is a task-specific machine within that family. It is not a general carrier waiting for a payload: it is built around a detection workflow, with the radar and the measuring wheel fitted as part of its equipment. Buyers comparing it with the wider line can browse the full Topsky range.

Radar on a robotic carrier

Ground penetrating radar sends electromagnetic pulses into the ground or into a structure and records the reflections from layers, voids, reinforcement and buried services. The quality of that record depends on three things: a steady speed, consistent antenna behaviour and accurate distance referencing. This is why conventional survey carts use measuring wheels.

The RXR-C11 brings these elements onto a powered chassis. The distance measuring wheel references position along the line. Remote speed control with continuously variable transmission lets the operator hold an even pace. Support for multiple antenna hosts with quick switching allows a crew to change the radar configuration for a different target without changing robots.

Technical Specifications

Specifications are as published by the manufacturer and are confirmed against the datasheet at quotation.

The manufacturer has not published the radar antenna frequency, the detection depth, the battery capacity, the operating temperature range, details of the remote controller, the radar software or the contents of the box; Robots Europa confirms each of these at quotation.

How does the RXR-C11 handle rough and wet survey ground?

Survey lines rarely run across clean, level surfaces. A municipal pipeline route can cross kerbs, verges and broken paving. A tunnel invert may be wet and uneven. A bridge approach can combine ramps with expansion joints.

The RXR-C11 meets this with a chassis designed for traction rather than speed alone. Each of its four wheels is driven independently, and steering is by differential control, so the robot can correct its heading without a separate steering linkage. Front and rear double wishbone independent suspension lets each wheel follow the ground on its own. This helps keep the chassis, and with it the radar, steadier over irregular surfaces.

The figures put this in practical terms. The robot crosses vertical obstacles of at least 120mm and has a chassis height of 125mm. Fitted with off-road tyres, it climbs gradients of at least 70% (or 35 °). It wades through water at least 250mm deep, and the robot machine carries an IP65 protection level against dust and water jets. Road tyres come as standard, with off-road and grass tyres as replaceable options, so the same robot can be set up for an asphalt carriageway in the morning and a grassed embankment in the afternoon.

Braking within 0.3m gives the operator precise control when stopping at a marked point on the line.

Why use a GPR robot instead of a hand-pushed radar cart?

A hand-pushed cart puts a person on the survey line for its full length. On live roads, in tunnels and in confined or contaminated spaces, that exposure is the main constraint on how, when and where surveys can be carried out.

A remotely controlled carrier separates the operator from the line. With a wireless remote control distance of at least 500m in open space, the RXR-C11 allows the operator to work from a protected position while the robot covers the ground. The robot is designed to replace humans for efficient operations in complex environments.

Consistency is the second argument. A powered robot with continuously variable speed control and a distance measuring wheel can hold a repeatable pace, which matters when surveys are repeated over time to track the development of a defect.

Endurance is the third. Continuous walking time of at least 3h on the 48V lithium battery system covers substantial lengths of survey line in one deployment. Load capacity of up to 30kg also leaves room for the radar equipment and accessories a survey requires.

Who is the Topsky RXR-C11 (RXR-C11) for?

The RXR-C11 suits organisations that carry out ground penetrating radar work regularly and want to reduce the time their staff spend on the survey line.

• Municipal authorities and utility operators responsible for pipelines and underground networks gain a way to inspect routes beneath streets and verges.
• Road and bridge owners, and the engineering consultancies that assess these assets for them, can apply it to quality and defect detection in pavements and decks.
• Tunnel contractors and operators can use it in bores where conditions are wet, dusty or restricted.
• Geotechnical and underground engineering survey firms benefit from its ability to carry radar across complex ground.
• Inspection service providers working for several clients can switch antenna hosts between jobs without changing platform.

Buyers whose task is not radar inspection, such as firefighting, scouting or a bare chassis for their own payload, will find other platforms in our UGVs category. Robots Europa is happy to advise on which platform matches a given application.

What is the Topsky RXR-C11 (RXR-C11) used for?

1. Underground engineering surveys: geological detection across complex sites before and during construction.
2. Municipal pipeline inspection: radar surveys along buried service routes beneath streets and public areas.
3. Road condition assessment: quality and defect detection in road structures without walking staff along live carriageways.
4. Bridge inspection: radar scans of bridge decks and approaches to locate defects and deterioration.
5. Tunnel lining surveys: detection of defects and disease, or structural distress, in tunnel structures.
6. Repeat condition monitoring: consistent, remotely driven survey runs that can be repeated to follow changes over time.

Summary

The RXR-C11 answers a simple question: why should a person walk the survey line when a robot can? It carries ground penetrating radar and a distance measuring wheel on a chassis built for difficult ground. Four-wheel independent drive and double wishbone independent suspension keep it moving across uneven surfaces, while IP65 protection and a wading depth of at least 250mm keep it working when conditions turn wet or dusty. Switchable antenna hosts adapt it to different targets, and remote control over at least 500m in open space keeps the operator clear of traffic, water and confined spaces.
