A third-generation weeding robot, armed with lasers and powered by AI, offers the ultimate labor-saving device — while also eliminating the need for chemical herbicides.
The Autonomous Weeder by Carbon Robotics can eliminate 100,000 weeds per hour, and clear 15-20 acres in a single day (numbers that require a person working an entire season to match).
Trundling down a row of crops, a battery of twelve cameras scan the ground, identifying weeds through machine-learning and killing them with a CO2 laser. CO2 lasers use reactions between nitrogen, helium, carbon, and oxygen to generate powerful beams of light that are concentrated through mirrors inside the laser.
The robot’s onboard supercomputer ensures millimeter precision with its laser so as to avoid accidently clipping crops.
“This is one of the most innovative and valuable technologies that I’ve seen as a farmer”, said James Johnson of Carzalia Farm in a statement, who has utilized Carbon Robotics’ technology on his farm.
