Weatherproof and self-charging, Tertill lives in your vegetable or flower garden and takes care of the weeding
Tertill uses a whacker string to cut down the weeds before they're barely visible
It measures 11.7 × 11.7 × 7.2 in (30 x 30 x 18.3 cm)
Tertill comes with 20 plant collars that are used to keep Tertill away from low-lying plants in your garden
The wheels are specially designed for its purpose: The scrubbing action of the wheels on the ground tends to kill weeds in their cotyledon stage
By now, you’re probably used to the vacuum cleaner driving around the house, taking care of your floors by itself. And the lawn is mowed automatically by another robot. Now, it’s time for those unwanted plants in your garden.
Tertill is the first garden-weeding robot. Tertill is a solar-powered robot, rugged enough to stay in the garden all season long, and smart enough to distinguish between a weed and a plant. As long as there’s a bit of sun once in a while, it’ll just keep going and going. And if there’s no sun, the weeds aren’t growing.
Tertill uses a string trimmer to chop down weeds and its wheels will damage pre-emergent weeds. They simply shrivel to almost nothing and return their nutrients to the soil.
Tertill distinguishes weeds from crops by height. As Tertill sees it, small plants are weeds, big plants are crops. If you have seedlings, place a plant collar around them to inform Tertill that this plant is wanted. You can remove the collar once the plant is well established.
Tertill is designed to live in your garden and require very little attention. Summer showers won’t bother it. And neither will cloudy days. The garden-weeding robot still collects some energy even on cloudy days and spends it carefully. So, the robot continues to operate on a reduced schedule during extended cloudy periods.
Tertill needs a small barrier to keep it within the garden. A garden fence, the wooden border of a raised bed, or any sort of edging that is two or more inches tall will all work.
Under normal circumstances you never need to charge Tertill’s battery – the sun does that. If Tertill has been in the dark for so long (months) that its battery is completely exhausted a USB connection can be used to charge the battery.
