Autonomous Weeder robot uses lasers to take out 100,000 plants an hour!
The fully autonomous machine runs on diesel and can operate around the clock, covering 15 to 20 acres (6 to 8 ha) per day, while its lasers leave the surrounding soil undisturbed to preserve its microbiology. The company bills its Autonomous Weeder as an economical solution to improving crop yields, especially for organic growers and those adopting regenerative farming practices to ensure the long-term health of their soil.

Carbon Robotics has been developing and beta testing its weed-killing robots since 2018 with the help of farmers, and has already sold out of its 2021 models, though pre-orders are now open for the 2022 line.
