autonomous lawnmower robot
Roomba's creator made an autonomous lawnmower robot
While most autonomous lawn mowers require people to lay down wire to define their boundaries, the Terra only requires wireless beacons to be placed around the perimeter of a lawn -- the idea being it's a simpler setup. Users will also have to drive the mower around their lawn once using a companion app to teach it where to go and where to avoid. The Terra has an hour of runtime and takes about two hours to charge fully, iRobot says. If it runs out of battery mid-route, it'll go back to its charger and pick up where it left off. It's completely weatherproof and is designed to live outdoors.
