Honda's humanoid robot Asimo finally has a friend -- and a way to mow its lawn. The company unveiled Miimo, an automatic lawn mower robot that works on your lawn several times a week, each time snipping only 0.12 inches off -- small enough that they can act as fertilizer. Miimo uses sensors to navigate and steer itself, and can tell which patches need more attention. It has a pin to prevent theft and can automatically return itself to a docking station. Miimo will cost you about $2,600 to $3,000, and is the first commercial robotic product for public use by the company.
