When it comes to installing curtainwalls, glass-related companies are designing and supplying products that can place components safely. An example of this can be found on a facade project in Reston, Virginia, where TSI Corp. partnered with robotics firm Raise Robotics to install curtainwall brackets.

Raise Robotics officials said the robot used for the project can semi-autonomously attach fasteners via artificial intelligence. It features various attachments, including a hammer drill and pulse torque driver. For this particular project, a V1 robot was used to scan anchor channels and install top-of-slab curtainwall brackets to specification. Raise Robotics also tested out a new layout attachment.

Raise Robotics chief operating officer Conley Oster told USGlass magazine in 2023 that the robot is designed specifically for bracket installations.

“That’s where most customers seem to have the biggest heartburn,” he said. “It’s in the layout and the anchor channel inspection scope of work. It doesn’t help that workers are leaning over the side of the building to complete the installation.”

The robot’s setup procedure involves uploading a layout detail drawing, erecting a workstation, loading material hoppers with installation hardware, specifying installation type and location and starting the installation sequence.

Oster said the traditional method of curtainwall bracket installation involves several steps with the same component for fastening tasks. This typically takes one to two hours per bracket for layout, installation and verification. However, the robot can complete a bracket every 10 minutes with 1/16-inch installation accuracy.
