Franklin Robotics has launched a Kickstarter to build Tertill: a solar-powered and weatherproof robot that weeds your garden every day. 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 lives in your garden and prevents weeds from becoming established. Using unique design elements and a variety of sensors, Tertill patrols the garden daily, avoiding plants and obstacles while looking for weeds to eliminate. Tertill has a very simple method of distinguishing weeds from plants: 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 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.
