Robotic lawnmowers are getting smarter all the time. Take Toadi for instance: it is a robomower with 4K camera and AI that moves around autonomously and cuts your grass while avoiding objects and animals. It can handle landscape up to 1.2 acres and slopes up to 45%.
The Toadi has 4 titanium coated blades. It has adjustable mowing height from 1.29″ to 3.54″. You can setup this robomower on your smartphone. Expected to ship in November. You can find out more about it here.
