Rats and other animals need to be highly at tuned to social signals from others so that can identify friends to cooperate with and enemies to avoid. To find out if this extends to non-living beings, Loleh Quinn at the University of California, San Diego, and her colleagues tested whether rats can detect social signals form robotic rats.

They housed eight adult rats with two types of robotic rat- one social and one asocial一for 5 our days. The robots rats were quite minimalist, resembling a chunkier version of a computer mouse with wheels-to move around and colorful markings.

During the experiment, the social robot rat followed the living rats around, played with the same toys, and opened caged doors to let trapped rats escape. Meanwhile, the asocial robot simply moved forwards and backwards and side to side

Next, the researchers trapped the robots in cages and gave the rats the opportunity to release them by pressing a lever.
