Abstract

To address the growing need for mechanization in agriculture- especially for repetitive and time-sensitive operations such as sapling planting and fertilizer application—this paper introduces AGRIBOT, a semi-autonomous robotic system tailored for efficient plantation processes. The robot incorporates a dual- Arduino setup: the first Arduino unit handles navigation, gate control for sapling release, and user alerts via a buzzer; the second Arduino oversees sapling detection through an IR sensor, activates a relay-controlled mini fertilizer pump, and operates a pair of servo motors responsible for loading saplings into the delivery pipe. Users can set the desired gap between saplings using manual switch inputs, after which the system executes the planting sequence automatically. At the end of each cycle, an audible alert provides user feedback, improving usability. Notably, the design is modular and allows coordinated functioning without requiring direct communication between the two controllers. Field simulations confirmed the prototype’s accuracy in spacing, dependable mechanical response, and consistent performance. AGRIBOT presents an affordable, adaptable solution ideal for small to mid- scale farms aiming to implement precision agriculture methods.
