Researchers at Purdue University have invented a technological device for building robots that will allow construction projects to be completed faster, with better quality, and at a lower cost.
The robotic system uses innovative mechanical design and advanced computer vision sensing technology to work in a variety of building types.
Our technology helps solve the construction industry’s site labor shortage by automating one of the key construction operations,” said Jiansong Zhang, assistant professor of construction management technology at Purdue Polytechnic Institute. There is a lot of uncertainty on construction sites, and construction robots must have the ability to deal with it effectively. This requires more advanced sensing and analysis technology than is commonly used on manufacturing today.”
The core component of this system is a customizable terminal manipulator that is capable of placing and securing items in a single pass, reducing the number of devices that would otherwise be required for one such operation.
In addition, the researchers designed a computer vision system specifically for this system that can identify building materials, has the ability to compare them with information within a database of information models of various building types, and track difficulties and safety hazards in various operations.
“The sensing of this system robotic arm is based on computer vision technology, rather than a limiting and costly sensing system, and we have the ability to perform multiple sensing tasks using only one type of sensor.” Zhang Jiansong said, “This system is more comprehensive in its skills, more reliable, and less expensive.”
The Purdue team is applying for a patent on this system.
The technology was presented at the Offshore Oil Equipment Conference (OTC) 2021 Technology Showcase on Feb. 10-11.
