A 12V 30Ah Lithium Iron Phosphate (LiFePO4) battery with a 30A Battery Management System (BMS) powers the robot, providing an operational duration exceeding three hours. To maintain the battery temperature within its optimal operating range, two 80mm x 80mm 12VDC fans were installed at the front and rear of the chassis to facilitate airflow within the battery compartment. A 12V blue diode laser engraver with a wavelength of 450 nm and a 4 Watt optical laser output was utilized for weed removal, chosen for its compact, portable design and its capability to deliver precise thermal energy to targeted weeds. The distance between the laser lens and the target was maintained at 5-10 cm to ensure optimal optical performance. The duration of laser exposure is modulated based on the identified weed species and its size, using empirical data from preliminary trials on the time required to induce complete necrosis.
