Here is another robot that helps you take better care of your garden. Tertill is a solar powered weeding robot with a weatherproof design. It features camber wheels, weed sensor, whacker, and status indicator lights. The robot differentiates between weeds and plants thanks to a sensor that activates when a plant tall enough touches the front of the unit.
So how do you keep the robot away from smaller plants? Simply put a plant collar around the ones that you would like to keep. Tertill gets rid of weeds using a spinning string trimmer. Like what you see? You can get yours for as low as $199 if you are an early supporter.
