If these little helpers would not cost as much as a laptop, i definitely would have already one cruising around in front of my house. As one of a series of companies, Honda has recently announced a new robotic lawn-mower model, called Miimo. It is able to cut 2-3mm of grass in several runs during a week of operation. Miimo navigates through a combination of timers, controls and sensors and of course around your buried no-go wire line. Miimo is powered by a high performance lithium-ion battery. It is self-charging, constantly monitoring its battery level and returning to its docking station when it needs to recharge. Here you can find the original Honda press release.
