Amazon has acquired Cloostermans, a Belgian company that makes technology used in warehouses, the company announced Friday. Terms of the deal weren't disclosed.

Amazon began working with Cloostermans in 2019, using its technology to help move and stack heavy palettes and goods, as well as package products together for delivery, the retail giant said.

Cloostermans will become part of Amazon Robotics, Amazon's division focused on automating aspects of its warehouse operations. The unit was formed after Amazon acquired Kiva Systems, a manufacturer of warehouse robots, for $775 million a decade ago.

Amazon continues to launch new machines in warehouses. In June, the company unveiled a package ferrying machine called Proteus, which it referred to as its first fully autonomous mobile robot. It's also deployed other robots that can help sort and move packages.
