iRobot, the company that has brought us robotic vacuums like the Roomba has had plans for years to develop an autonomous robotic lawn mower. Now they are just one step closer after receiving FCC approval to build its first robotic lawn mower. Why FCC approval? Well, the robotic lawn mower would wirelessly communicate with signal beacons to understand its boundaries and not veer off to cut your neighbors grass or worse, the asphalt road or concrete driveway.
