"LOCA (Lunar Organization and Cleaning Assistant) works inside of the Lunar Gateway. LOCA’s purpose is to keep the gateway clean and organised for the astronauts that are spending time there. LOCA is programmed to organise things based on colour. The camera on top of the robot allows it to see colours and then the manoeuvrable arms place objects in specific areas of the Lunar Gateway. It uses its vacuum and cleaning wipes to keep the Lunar Gateway dust and germ free. The proximity sensor prevents LOCA from crashing into objects. LOCA is about 4 feet tall and 1.5 feet wide."
