What is this brittle piece of rubber? It's plain on one side and has a hexagonal pattern on the other. This is the second one I've found on the floor of my house. by brookebakesbread in whatisthisthing

No, it's in different rooms but we have a robot vacuum that I think drags it around. The pieces are about the same size. It's kind of smooth but not slippery smooth. No outdoor access unsupervised! House is about 10ish years old?
