When Carbon Robotics started up four years ago, the focus was on development of vision systems and weed identification, with an eye toward precise control. The differentiator for this startup, however, wasn’t a more precise spraying system, it was the use of lasers. In effect, the company has designed an implement — the LaserWeeder — that identifies weeds on the go and kills them with a beam.
Electrical weeding is an option for eliminating escaped weeds in numerous agricultural industries. This equipment uses a charged electrode to treat and kill weeds with high voltage electricity (up to 15 kV) as an effective and systemic form of late-season control.
