Meet the Tertill: a solar powered weeding robot that lets you get rid of annoying weeds and take better care of your plants. It has a sensor that detects weeds and whacks them using a string trimmer. Tertill is waterproof and connects to your smartphone via Bluetooth.
The robot gets rid of weeds without any chemicals. It comes with a weed whacker, sensor, status indicator, and camber wheels. Worried about your new plants getting removed by this robot? Simply put a plant collar around them. Tertill uses a four-wheel-drive system to move through soft soil, sand, and mulch. Expected to ship early next year.[where to get it]
