Robot Builds Brick Wall at Human Pace

In the United Kingdom, the WLTR robot now builds brick walls. The machine works under any weather condition and needs only one human supervisor. It lays the equivalent of five bricklayers and one assistant’s worth of bricks in one hour.

The WLTR robot requires pallets of bricks and a completed first layer to begin work. It aligns bricks with a margin of error of just two millimeters—a level of precision rare among human professionals. The robot also uses a special adhesive instead of traditional cement.

This change significantly reduces environmental impact, as cement production accounts for roughly 6% of global carbon dioxide emissions. Developers hope the technology will attract younger workers to the construction industry, framing the role as similar to playing computer games. The robot still requires further development, as other humanoid robots struggle with complex tasks.
