Carbon showcases LaserWeeder, Pi sensors

Carbon Robotics and Raspberry Pi were featured in separate agriculture-related technology updates on May 15, pointing to two different uses of AI and edge hardware in the field. Carbon Robotics has been promoting its LaserWeeder line as a chemical-free weed-control system for commercial farms, while Raspberry Pi published details of a predator early-warning system deployed in Pakistan with WWF-Pakistan and Lahore University of Management Sciences, or LUMS. The two systems address different problems, but both center on machine vision operating outside a traditional farm office. The first is aimed at weed removal in crop rows. The second is designed to detect predators near settlements and livestock areas. ### What exactly did Carbon Robotics show? Carbon Robotics says its LaserWeeder combines computer vision, deep learning, robotics and lasers to identify weeds and destroy them in the field. The company’s website describes the LaserWeeder as the “first & only commercial LaserWeeder” and says the product is owned and operated by more than 100 growers across North America, Europe and Australia. Carbon’s current marketing centers on the LaserWeeder G2 line. The company says the G2 comes in multiple sizes and configurations, including 200, 300, 400, 600 and 1200 models, and is intended to fit different farm sizes, crop types and field layouts. Carbon says the system can cut weed-control costs by up to 80% versus traditional methods. ### How does the LaserWeeder kill weeds without herbicides? (carbonrobotics.com) Carbon says the machine uses targeted thermal energy to destroy the weed meristem, the growth tissue that allows regrowth. The company says its laser modules operate outside the visible range at a 10.6-micron wavelength and are intended to kill weeds without disturbing soil or damaging crops. Carbon also says the system can eliminate more than 100,000 weeds per hour. (carbonrobotics.com) On its product pages, the company frames that throughput as a way to replace hand labor, herbicide applications and mechanical cultivation passes. Those claims appear in company materials and were not independently verified in the sources reviewed here. ### What was the Raspberry Pi system in Pakistan? (carbonrobotics.com) Raspberry Pi said on May 15 that WWF-Pakistan and the National Center of Robotics and Automation at LUMS developed and deployed an AI-powered Predator Early Warning System in the Gilgit-Baltistan mountains. The company said Raspberry Pi 4 boards sit at the center of solar-powered camera traps installed in high-risk zones near human settlements. (carbonrobotics.com) Raspberry Pi said the system has been in use since 2022. According to the company, the devices run a trained AI detection and alert algorithm at the edge and are used to help communities protect livestock while reducing harm to wildlife. ### Why were the Pakistan devices described as low-cost sensors? (raspberrypi.com) Raspberry Pi 4 is a single-board computer commonly used in low-cost embedded projects, and Raspberry Pi’s own account presented the Pakistan deployment as a practical edge-computing build rather than a custom industrial platform. A 2025 review in the journal Agriculture said Raspberry Pi can serve as a cost-effective central unit for sensor-driven automated decision support in precision agriculture and related monitoring tasks. (raspberrypi.com) The Pakistan system was described by Raspberry Pi as solar-powered and mobile-connected, with local processing on the device. That architecture generally reduces the need for more expensive on-site computing hardware, though Raspberry Pi did not publish a system price in the material reviewed here. (raspberrypi.com) ### Are these two technologies part of the same project? Carbon Robotics and the WWF-Pakistan system are separate efforts by different organizations in different settings. Carbon’s equipment is a commercial farm implement for weed control, while the Pakistan deployment is a conservation and livestock-protection system built with WWF-Pakistan, LUMS and Raspberry Pi technology. Carbon’s website continues to list the LaserWeeder G2 product family and field-use claims, and Raspberry Pi’s May 15 post identifies WWF-Pakistan and LUMS as the named participants in the predator-warning project.
