Robots are already capable of many things for us. That applies to cleaning our aquariums. MOAI is a smart robot that gives you a close-up view of your fishtank and cleans it on a schedule. It uses adaptive mapping and ultrasound navigation to get the job done.
You can start, stop, and schedule cleaning sessions from your smartphone. The robot goes back to its home base when it needs to charge. Expected to ship in July. More info is available here.
