The COSCR project sought to develop a prototypic mobile construction robot, capable of autonomously navigating construction sites and undertaking required jobs based on data extracted from a BIM model. The robot is designed to deliver construction activities that may otherwise be repetitive or potentially hazardous, such as drilling at height. As a first proof of concept, the project focused on a drilling and anchor insertion application which was trialled on a live construction site at Skanska’s Featherstone Building project in central London in early 2021. The project brought together the construction expertise from Skanska, equipment expertise from Skyjack, legislative expertise from the BRE and robotic expertise from InnoTecUK, ABB and HAL Robotics to develop a holistic solution capable of handling the disparate challenges of on-site construction automation.
The COSCR platform comprises a robust mobile base, site sensing technology and BIM-linked software systems that enable it to navigate safely and accurately around a construction site.
It can be operated manually or autonomously. In manual mode, an operator uses a controller to move the robot around the site. In autonomous mode, the robot uses its onboard sensors, as well as maps derived directly from BIM (Building Information Modelling) data, to navigate itself safely around the site and perform tasks that have been scheduled by the user.
It has been developed to specific size and weight constraints to maximise its potential to access the tightest corners of any site. The platform is tracked, which enhances the manoeuvrability, and features a telescopic mast fitted with a robotic arm, enabling it to reach heights of up to 4.2 metres.
