Weatherproof and self-charging, Tertill lives in your vegetable or flower garden and takes care of the weeding.With Tertill, gardeners can now enjoy weed-free vegetable and flower gardens, without the monotony and frustration of weeding. Organic gardeners can breathe easy and enjoy a weed-free, chemical-free garden all season long.
Created by roboticist Joe Jones – inventor of the Roomba – Franklin Robotics’ Tertill is designed to live in your garden and take care of the weeding, come rain or shine.Tertill has a very simple method: weeds are short, plants are tall. A plant tall enough to touch the front of Tertill’s shell activates a sensor that makes the robot turn away.
A plant short enough to pass under Tertill’s shell, though, activates a different sensor that turns on the weed cutter. Tertill whacks weeds using a spinning string trimmer, which cuts the weed off near the ground. Because Tertill lives in your garden and goes looking for weeds every day, weeds are always small when the robot finds them.
Tertill never lets a weed develop the leaves it needs to replenish this energy, so eventually the weed gives up and dies.Tertill gets its power from the sun. When there is sunlight—even on cloudy days—Tertill’s solar cell converts the light into electricity. The robot stores the energy in a battery. You don’t need to charge or replace Tertill’s battery. Tertill uses its stored power smartly—during cloudy stretches, when less power is available, it patrols for weeds less often. Tertill is more aggressive during periods with more sun. Fortunately, weeds grow more slowly when they have less light.
