Weed-killing robot

Franklin Robotics, the Massachussetts company that brought us the Roomba, has designed a solar-powered robot to weed the garden. Tertill is a round, 2.5-pound bot that uses sensors to identify weeds, then trims then near the ground using weed wacker. How can it tell the difference between a weed and a plant? Anything that’s short enough to go under the robot is considered a weed, and anything taller is considered a plant. Tertill will come with a collar to place around short plants you want to keep.
