There's a new helper robot for homes called Droplet, but it has no intention of usurping Roomba's territory -- in fact, you can think of it as a Roomba for your garden. It's probably not capable of killing snakes like its badass indoor counterpart, but it can care for your plants without input. Technically, Droplet's a smart sprinkler, but it's actually more like an automated hose that aims only at plants (or anything you want) up to 30 feet away, since it was created as a means to conserve water. Of course, you'll have to configure it a bit beforehand: after adding your plants' names on Droplet's interface using a phone, laptop or tablet, you'll have to aim water at each of them, so the system can remember their locations. The robot then taps into various sources via WiFi to look up each plant's needs to determine how often and how much it should be watered. In the event that rain's coming your way, the device will hold off on doing its gardening duties, as it also gets real time data from thousands of weather stations.
