What Weier Technology does

Weier Technology (纬尔科技) is a Shenzhen-based precision agricultural robotics company founded in 2021 by a Tsinghua University team with prior experience at DJI and Momenta. The company develops and sells intelligent agricultural robots, including the VTM-09B and VTM-03A cotton topping robots, an intelligent row-guided weeding robot, and a rice seedling quality monitoring system (Paddy Field Manager / 稻田管家), all built on the proprietary 'Jingwei' (经纬) full-stack platform that combines edge AI perception, cloud-based agricultural large models, an all-electric four-wheel-drive chassis, and per-plant precision implements. The company holds 59 patents (23 invention, 18 utility model, 15 software copyrights, 3 design) and reports 110,000 mu of cotton topping data collection, 400-600 mu/day per-unit operating efficiency, and yield improvements of 5% per mu for cotton topping and 8-12% per mu for intelligent weeding.

The company serves large-scale commercial farms, state-owned agricultural divisions (notably Xinjiang Production and Construction Corps divisions 1, 6, 7, and 8), Beidahuang Group, agricultural cooperatives, and specialty crop growers across 31 Chinese regions as of October 2025. Revenue is generated primarily through direct hardware sales of robots and implements, supplemented by cloud platform subscriptions for the rice seedling monitoring product, agricultural ADAS modules, and remote OTA after-sales service. Go-to-market combines direct enterprise field sales, regional agricultural machinery dealer partnerships, government agricultural bureau procurement channels, and demonstration-led selling at major trade shows including the China International Agricultural Machinery Exhibition, supported by CCTV, People's Daily, and regional media coverage. Customers include Fangcao Lake Farm (620,000 mu cotton deployment with reported ~500 kg/mu yield, up 26 kg year-over-year), Tianye Group, Arun Banner, and various SMB cooperatives. The company has completed three rounds of venture financing (Series A in October 2024, tens of millions RMB) and was recognized as a National High-tech Enterprise in December 2024.

The robots are sold to large-scale farms, agricultural cooperatives, and government agricultural bureaus across China's major crop regions.

Product overview

Weier Technology offers a portfolio of precision agricultural robotics products centered on the '经纬' full-stack intelligent agricultural robot platform. The core product line includes four main robots: the Cotton Topping Intelligent Robot VTM-09B (self-propelled, 400-600 mu/day, 108 robotic arms) and VTM-03A (first-generation, 200 mu/day), the Intelligent Row-guided Weeding Robot (nationwide first, up to 100 mu/hour), and the Paddy Field Manager (seedling monitoring system). Additional offerings include the Precision Spraying Robot and transplanting quality monitoring module. The '经纬' platform provides the underlying technology stack through four integrated modules: 灵枢 (edge intelligence), 天枢 (cloud intelligence with agricultural large model), 地枢 (adaptive chassis), and 星枢 (precision implements), all connected via the proprietary 纬尔智农云平台. Together, these products enable precise, efficient, green, and safe agricultural production across cotton, rice, corn, soybeans, sugar beets, and other field crops.
