Robot weeder is on the way

Monday, December 3, 2012

It started out as a robot that would cut the grass in urban parks. Somebody thought that spinning blades were a bad idea with kids and dogs on leashes around, and so the idea evolved into an automated lettuce weeder, according to The Economist magazine.

The electric-powered Lettuce 'Bot, brainchild of Stanford University-trained engineers Jorge Heraud and Lee Redden, takes pictures of passing lettuce plants, compares them to a database of more than one million images of lettuce taken from all possible angles and instantly decides if they should live or die. A shot of concentrated fertilizer out the back end kills weeds and the remaining lettuce gets a growth blast as well. A version of the machine, currently under development, aimed at organic lettuce producers, favours those old spinning blades.

The makers promise that the robots will be cost-competitive with hand weeding. BF
