About Agar Lub Cuab Yeej Ua Liaj Ua Teb Tsis Yog Neeg Tsav

Agar yog ib lub platform robotic uas thaiv nws tus kheej kom ncaj rau kev ua liaj ua teb precision saum thaj av tsis tiaj tus. Lub platform no muaj peev xwm ua hauj lwm los ntawm remote control, teeb tseg kom raws li txoj kev GPS uas twb muab teem lawm, los sis khiav tsis yog neeg tsav siv obstacle avoidance sensors. Cov motor uas siv battery zuj zus rau txhua lub log pab kom tig tau tim ntsej tim muag qhov chaw. Cov log muaj peev xwm hloov chaw kom haum rau ntau hom kev sib nrug ntawm cov kab qoob loo, thiab lub platform kuj hloov kho tau raws li kev nqis roob uas siab txog 30 degrees. Cov pob emergency stop thiab cov mechanical bumpers pab txhawb kev nyab xeeb rau tus siv. Cov khoom sib xyaw ntawm hlau, hlau stainless, thiab aluminium raug pleev powder coating.

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.
