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.Welcome to Old Garden Tools collection of Weeding Tools. We have laid our images out in museum style so that you may concentrate just on the images without any other distractions.
Organic gardeners can breathe easy and enjoy a weed-free, chemical-free garden all season long.
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.
A plant tall enough to touch the front of the shell activates a sensor that makes the robot turn away.
A plant short enough to pass under the shell, though, activates a different sensor that turns on the weed cutter.
This ingenious device is comprised of a slightly tapered ash shaft along which is a copper tube inset into a groove.
