MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202621042668 A) filed by Sage University, Indore, Madhya Pradesh, on April 2, for 'system and method for autonomous robotic laser based weed elimination.'
Inventor(s) include Dr. Prashant Jain; Prof. Snehlata Mishra; Dr. Kuntal Barua; Aayush Hariyale; and Keshav Malakar.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "An autonomous robotic system (102) for laser-based weed elimination comprises an optical imaging system (104), a thermal sensor (106) configured to detect thermal signatures of plant targets, a laser (108) configured to emit thermal energy for plant tissue destruction, and a hardware processor (110). The hardware processor (110) receives optical image data of plants from the optical imaging system (104), compares the optical image data against predefined crop characteristics, receives thermal data from the thermal sensor (106) to verify the identified weed targets, determines adaptive thermal energy parameters, and generates control signals for the laser (108) to deliver adaptive thermal energy to verified weed targets for selective weed elimination. The system further comprises a ring-shaped chassis (112) positioning the optical imaging system (104) and thermal sensor (106) for 360-degree access around crop plants without physical contact, enabling precise weed targeting while preserving crop safety and eliminating chemical herbicide dependency."
