Robotic Roadworks & Excavation System — Revolutionizing Utility Excavation Methods

ULC Robotics, Inc. and SGN are developing an advanced 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

01. 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.

02. 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.

03. Higher Repeatability

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

04. 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.

05. Minimize Disruption

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

06. Reduce CO2 Emissions

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

Project Overview

Traditional excavation methods in the utility industry face a wide range of challenges such as third party damage, disruption to traffic, road closures and excessive carbon emissions. While our world has been rapidly transformed by technology, roadworks are still carried out using backhoes and dump trucks. ULC Robotics and SGN are developing an advanced robotic system to revolutionize the way utility companies, energy networks and other industries carry out roadworks. The Robotic Roadworks and Excavation System project is combining below-ground locating sensors, artificial intelligence, machine vision and new excavation methods for safer, faster and smarter roadworks.

End-to-End Process

01. Below Ground Sensing

Before beginning the actual excavation process, the RRES will deploy integrated below-ground sensors to ensure the robot is digging in the correct location and attempt to identify any other buried utilities that may impede the work.

02. Coring and Cutting Roadways

To gain access to the pipeline network under the street, the robotic system will cut a core out of the road surface. The core will then be picked up and set aside for reinstatement at the end of the project.

03. Automated Soft Touch Excavation

ULC Robotics is combining machine vision and sensors with newly developed soft-touch excavation methods to enable the robot to rapidly and autonomously remove the soil one layer at a time while identifying and avoiding other buried utilities.

04. Conduct Work on the Pipe

Once the pipeline has been exposed, the robot will be capable of installing a specialized fitting onto the pipe. Future development of the RRES will aim to expand the range of operations the robot can perform.

05. Backfill and Reinstatement

Lastly, the Robotic Roadworks and Excavation System will backfill the opening in the street and reinstate the core to provide a complete, end-to-end solution.

Robotic Arm Testing

Over the course of the RRES project, our team looked at the range of robotic arms in the market and selected one that is most ideal for the application being developed. In January 2019 our team began configuring, programming and testing the selected robotic arm.

Soft Touch Excavation

To deliver improvements to the excavation process, we are developing new soft-touch excavation technology and methods. This works to reduce damage to buried utilities while improving the efficiency of excavations in urban environments.

Machine Vision Development

To automate excavation activity, the Robotic Roadworks and Excavation System is being integrated with a range of sensors to deliver real-time feedback to enable the system to identify and work around buried assets and other obstacles.
