MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202621022812 A) filed by Rajarambapu Institute Of Technology, Walwa, Maharashtra, on Feb. 26, for 'autonomous multi-modal precision weed management robot with root sensing.'
Inventor(s) include Avadhut Vasant Autade; Rajvardhan Jayant Jagatap; Kshitij Mahesh Dewarde; Prof. Juber M Mulla; Dr. Prasad V. Shinde; and Suhas A Jadhav.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "Autonomous Multi-Modal Precision Weed Management Robot with Root Sensing This invention describes an autonomous precision agricultural weed management system configured to perform selective, root-aware, and environmentally sustainable weed control. The system integrates multi-spectral RGB and near-infrared imaging with machine-learning-based growth stage classification to accurately identify and localize weeds. A subsurface sensing mechanism assesses root depth and density prior to treatment, enabling adaptive intervention at the root level. Based on fused above-ground and below-ground data, the system autonomously selects among precision powdered agent dispersion, micro-volume organic-compliant liquid droplet application, or localized non-chemical thermal or laser-based neutralization, with treatment parameters dynamically adjusted for efficacy and conservation. Excess applied material is actively recovered, filtered, and recycled to reduce chemical consumption and soil residue. GPS-guided navigation ensures precise field coverage and geo-referenced treatment logging, while environmental monitoring inhibits drift-prone operations. Multiple units coordinate through a mesh communication network to prevent redundant coverage. The invention provides scalable, resource-efficient weed management suitable for conventional and organic farming environments."
