About Agar Karetao Ahuwhenua Motuhake
Ko Agar he papa karetao whakatikatika-taiao i hangaia mō te ahuwhenua tino tika i runga i te whenua kōrikoriko. Ka taea te whakahaere i te papa mā te mana whakahaere mamao, mā te hōtaka kia whai i tētahi ara GPS kua whakaritea, ā, ka taea hoki te whakahaere motuhake mā ngā pūoko aukati-ārai. Ko ngā mōta motuhake e whakakahangia ana e te pūhiko kei ia wira e taea ai te huri i te wāhi kotahi. Ka taea te whakanoho anō i ngā wira kia rite ki ngā tawhiti rārangi hua rerekē, ā, ka urutau te papa ki ngā pari tae noa ki te 30 nekehanga. Ko ngā pātene aukati-ohorere me ngā ārai miihini e tautoko ana i te haumarutanga o te kaiwhakamahi. Ko ngā wāhanga rino, rino kore-waikura, me te konumohe kua paatu-pūkahukahu.
The Recognition
About the A' Design Award Parahi
Ko Agar Karetao Ahuwhenua Motuhake te toa o te A' Design Award Parahi, he whakaaetanga tino whai mana e hoatu ana ki ngā hoahoa kōeke e tohua ana mā te auaha, te mahi mōhio me te whakaaro hōhonu. Ko ngā toa Parahi he mahi pukenga e rite ana, he auaha mīharo, e whakatūturu ana i te wheako nui, te whakaaro me te mōhio-ā-ringa o ā rātou kaihoahoa.

- 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.
