FOR IMMEDIATE RELEASE

Agar: Agricultural Autonomous Robot

Vladimir Zagorac, a product designer based in Belgrade, Serbia, has unveiled Agar, a groundbreaking agricultural autonomous robot designed to revolutionize precision agriculture. Agar is a universal self-leveling platform for precision agriculture, serving as a versatile tractor replacement that is mobile on extremely uneven terrains and under heavy loads. The design, inspired by the latest design tendencies and strict technical limitations, aims to exceed the standards set by leading companies in the Smart Farming industry. With a focus on aesthetics that emphasize robustness, dynamics, and strength, Agar adapts to the terrain, type, and height of the crop at any working height.

The robot boasts unique properties, including remote control capabilities, programmable movement on predefined GPS paths, and autonomous operation using obstacle avoidance sensors. Its independent battery-powered motors on each wheel enable turning in place by reversing the left and right set of wheels. Additionally, Agar prioritizes user safety with emergency stop buttons in the corners of the vehicle and mechanical safety bumpers.

Constructed using laser-cut, pressed, and welded steel, stainless steel, and aluminum, Agar's specifications include a length of 179-222cm, a maximum width of 147cm, a height of 137-178cm, and a weight of 740kg. The design's keywords include "robot," "autonomous," "universal," "dynamics," "strength," and "perseverance."

Agar's interaction is facilitated by wheel motors protected within a movable leg frame, allowing for the main battery pack to be easily changed by removing a magnetic fascia mask. The design also accommodates additional top battery packs, a robotic arm, or a solar panel using roof profiles on the main shell. The beveled shell provides good clearance, while the latest RGB LED signaling lights arranged in a 360 design inform the user of the working status and illuminate the path.

The design project for Agar lasted a year and was implemented in Belgrade, Nis, and Boljevac. It began with an existing construction of a working prototype developed by Coming and the Faculty of Mechanical Engineering in Nis, with special attention given to the stability of the robot bearing an agricultural machine. The design overcame numerous challenges, including the development of the main shell, roof housing, and mobile and stationary modular assemblies for multiple uses, as well as the positioning of sensors, radar, and lidar.

Vladimir Zagorac's Agar is a self-leveling universal robotic platform intended for precision agriculture on extremely uneven terrain. Its dynamic design composition features a complex arrangement of directed details, balanced masses, and proportions, with similar angles in both lowered and raised positions. The product prioritizes versatility, user safety, and modern aesthetics, culminating from a year-long development process that focused on stability for slopes up to 30 degrees.
