These gardeners would have green thumbs — if they had thumbs.
A class of undergraduates at the Massachusetts Institute of Technology has created a set of robots that can water, harvest and pollinate cherry tomato plants. The small, $3,000 robots, which move through the garden on a base similar to a Roomba vacuum, are networked to the plants. The robots can sprinkle the plants from a water pump when they need water, and use their arms to pluck a ripe fruit. The robots' creators hope their technology eventually could be used by farmers to reduce the natural resources and the difficult labor needed to tend crops.
