The Design

About Agar Robô Agrícola Autônomo

Agar é uma plataforma robótica autonivelante concebida para a agricultura de precisão em terrenos irregulares. A plataforma pode ser operada por controle remoto, programada para seguir um percurso GPS predefinido ou funcionar de forma autônoma por meio de sensores de desvio de obstáculos. Motores independentes alimentados por bateria em cada roda permitem o giro sobre o próprio eixo. As rodas podem ser reposicionadas para se adequar a diferentes distâncias entre as linhas de cultivo, e a plataforma adapta-se a declives de até 30 graus. Botões de parada de emergência e para-choques mecânicos garantem a segurança do usuário. As peças de aço, aço inoxidável e alumínio recebem pintura eletrostática a pó.

Behind the Design

Press Kit

Credits, team members and technical details provided by the designer.

Unique Properties: The robot can be remotely controlled, programmed to move on a predefined GPS path, and autonomous using obstacle avoidance sensors. Independent battery powered motors on each wheel enable turning in place by reversing the left and right set of wheels. All visible electromechanical parts are protected by the robust constructions of movable and fixed frames. User safety is also ensured by emergency stop buttons in the corners of the vehicle and mechanical safety bumpers.
Dimensions & Packaging: Lenght: 179-222cm, Width: max. 147cm, Height: 137-178cm. Weight: 740kg
Tags: Robot, Autonomous, Universal, Dynamics, Strength, Perseverance
Production Technology: Laser cut, pressed and welded steel, Stainless steel and aluminum, powdercoated
Design Challenge: The form was developed over a year in iterations, respecting and emphasizing the multi-functionality of the adaptable platform. The creative process included elaboration of the main shell, the roof housing, and the mobile and stationary modular assemblies for multiple uses. The large number of visible components presented a challenge, overcome by using related angles. Directing details, balancing masses and proportions, and positioning of sensors, radar and lidar, was perfected in stages.
Research: The design project started in March 2023 using an existing construction of a working prototype, developed by Coming and the Faculty of Mechanical Engineering in Nis. Special attention in the design was devoted to stability of the robot bearing an agricultural machine, since the platform adapts to terrain with slopes of up to 30 degrees in all directions. For this purpose, mounting weights were added to the final solution, considering that the weight of the robot should not have exceeded 750kg.
Inspiration: Agar is a universal selfleveling platform for precision agriculture, a tractor replacement, mobile on extremely uneven terrains and under heavy loads. The form was modeled following the latest design tendencies, with strict technical limitations, to match or exceed the standards set by leading companies in the Smart Farming industry. Aesthetics emphasize robustness, dynamics and strength, equally present at any working height of the vehicle that adapts to the terrain, type and height of crop.
Project Duration: The design project lasted for a year, and was implemented in Belgrade, Nis and Boljevac
Operation Flow: Wheel motors are protected within a movable leg frame. The main battery pack can be changed by removing a magnetic fascia mask. Additional top battery pack, robotic arm or solar panel can be placed using roof profiles on the main shell. The wheels can be repositioned to the inside, allowing use between crop rows of different distances. The beveled shell gives good clearance, while latest RGB LED signaling lights arranged in a 360 design inform the user on working status and illuminate the path.
