Tweet about this product: Tertill: A solar powered robot that lives in your garden and takes care of the weeding @FranklinRobotic

Tertill is a solar powered, autonomous, self-sufficient robot. It lives in the garden, and every day it charges itself in the sunlight, patrols the garden, avoids plants and obstacles, and chops down emerging weeds.
Friendliness and simplicity are designed in. Setup requires only a fence around the garden, and small plastic collars around seedlings; no wires or beacons are necessary, there's no programming of any kind, and chemicals are no longer needed for weed control.
Using a simple, robust sensing suite, we use a height-based approach to distinguishing plants from weeds: tall things are plants, short things are weeds that get cut with a string trimmer. Proprietary algorithms ensure maximum coverage and autonomy.
