The LG Lawn Mowing Robot will make mowing the lawn a chore you won’t even have to think about. It looks like a Roomba but moves around your lawn to mow grass. The device can also tell when something is in the way like a tree, and move around it to keep cutting grass. No official word yet on when it's out and how much it'll cost, but if you hate mowing the lawn, this is totally worth buying.
