Robotic Roadworks &
Excavation System


Transforming Utility Excavation and Roadworks

ULC Technologies, LLC and SGN are developing an advanced, all-electric robotic system to revolutionize the way that roadworks are performed. The Robotic Roadworks and Excavation System (RRES) will replace conventional methods of excavation performed daily by gas networks on transmission and distribution mains and other underground infrastructure.

Key Benefits

Improve Efficiency

RRES aims to expand the use of innovative core and vac methods to improve the efficiency of the operation, minimize time in the street and reduce costs.

Lower Risk of Damage

Using innovating soft-touch excavation technology and methods, artificial intelligence and machine learning, RRES aims to reduce accidental damage to buried utilities.

Higher Repeatability

Automating methods of carrying out works on the distribution and transmission system ensure routine works are completed uniformly with high precision.

Enhance Safety

RRES will limit the need for utility workers to enter excavation to improve worker safety. Minimized risk of accidental damages also improves public safety.

Minimize Disruption

RRES project sites will take up less space in the street to minimize disruption to communities and local businesses.

Reduce CO2 Emissions

By reducing the need for heavy construction vehicles on sites, the RRES project will enable gas networks to reduce carbon emissions.

How It Works

Below Ground Sensing

Prior to starting excavation, and during the excavation process, RRES uses sensors such as Ground Penetrating Radar and electromagnetic waves to scan the ground to identify buried assets in its excavation path. Advanced AI will be used to detect buried infrastructure and the target assets prior to cutting the road surface.

Cutting The Road Surface

Our team has designed a custom concrete cutting chainsaw for use as an end effector for the robotic arm. This new and unique tool will enable RRES to make flexibly-shaped and sized cuts in a wide array of road surface materials.

Core Removal

Prior to cutting the road surface, RRES drills a small pilot hole in the road. Once the core is cut, this pilot hole is used to lift the core and set it aside. At the end of the project, the core is lifted and set back in place to reduce disturbance to the roadway and maintain their strength and integrity.

Soft-Touch Excavation

RRES uses a compact, custom-designed vacuum excavation head with integrated super-sonic air nozzles to agitate and remove soil without the risk of damage to buried assets. Machine vision will be used during the excavation process to identify objects and guide activities through the excavated keyhole.

Backfill and Reinstatement

RRES will be equipped with additional end effectors to help backfill the excavation, compress soil and secure the core back in place to complete the end-to-end roadworks process.

Machine Learning And Machine Vision

In order to embed the RRES with the ability to ‘see’ its environment, the RRES team is developing 3D visualization techniques to capture 3D point clouds of the excavation and surrounding site.
