What Is An Agricultural Robot?

The global agricultural robotics market is projected to grow from USD 8.13 billion in 2025 to USD 26.35 billion by 2032, driven by demand for automation in harvesting and weeding.

And how are they injecting new vitality into modern agriculture through advanced technologies, particularly robotic chassis technology?

Agricultural robots are automated equipment specifically designed for agricultural production. By integrating sensors, artificial intelligence, computer vision, and automatic control technologies, they can autonomously or semi-autonomously perform various agricultural tasks, such as sowing, fertilizing, weeding, harvesting, and livestock management, addressing challenges like labor shortages and climate change. Their core value lies in improving agricultural production efficiency, reducing costs, and enhancing the quality of agricultural products, while also promoting the development of intelligent, precise, and sustainable agriculture.

In agricultural robot systems, the robot chassis, as the mobile platform that carries sensors, actuators, and control systems, is a key component that determines the robot's stability and adaptability. As a professional robotic chassis developer and manufacturer, Xspirebot specializes in providing highly adaptable and reliable customized chassis solutions for agricultural robots.

Technical Features of Agricultural Robot Chassis

All-Terrain Adaptability

Agricultural applications involve complex terrain, ranging from flat rice paddies to rugged mountain orchards, which require a chassis with strong maneuverability. Therefore, the tracked chassis utilizes an engineered track design to significantly reduce ground contact pressure, improving maneuverability in muddy and soft soils. The four-wheel independent drive chassis utilizes a double wishbone independent suspension, with each wheel equipped with a high-torque brushless motor. This allows for easy traversal and climbing of obstacles, ensuring continuous and stable output under high-load, low-speed conditions.

High-Precision Navigation And Positioning

Precision operation is a core requirement for agricultural robots. The chassis integrates multi-source data fusion technologies, including laser radar, IMU, and visual sensors, to achieve centimeter-level positioning accuracy. A built-in CAN bus communication protocol enables efficient data exchange between the chassis and upper-level controllers and operation modules. Precise speed control and trajectory tracking algorithms ensure stable operation along pre-set paths, meeting demanding requirements for precision seeding and variable-rate fertilization.

Flexible Movement And Obstacle Avoidance

Farmland faces a variety of obstacles, such as crops and rocks, requiring the chassis to possess agile obstacle avoidance capabilities. The chassis with four-wheel independent drive and differential steering provides omnidirectional mobility, enabling lateral and diagonal travel, on-the-spot steering, high maneuverability, and flexible route adjustment. Equipped with ultrasonic and collision sensors, it enables autonomous obstacle avoidance and route replanning.

High Payload And Strong Scalability

Agricultural chassis must carry equipment such as seed drills, fertilizer spreaders, and harvesting robots, requiring a strong load-bearing capacity. To this end, the chassis features a modular design with independent suspension, a one-piece welded frame, integrated overload protection for the powertrain, high-torque in-wheel hub motors, and a high-gear reduction gearbox, capable of carrying equipment twice its own weight. Furthermore, the chassis includes interfaces for mounting robots and sensors, supports ROS and Linux, and comes pre-installed with low-level drivers, facilitating the rapid integration of specialized agricultural modules such as robots, spray booms, harvesting devices, and cameras.
