How to Choose an Agricultural Robot Chassis

Have you ever encountered this scenario — your agricultural robot, while working:

On the slope, the equipment slipped laterally and lost directional control.

In the wet fields, the wheels spun aimlessly, lost power, and could not move forward.

Between narrow rows, the turning radius is too large, it crushes crops, or it is impossible to turn around.

These problems are not due to inaccurate navigation or suboptimal algorithms. The root cause lies in the robot's chassis.

Traditional chassis often rely on differential steering or centralized drive systems, which are prone to slipping and difficult to steer on slopes, wetlands, and narrow ridges.

So, what is the correct solution?

Technological breakthrough: Independent steering + independent drive

For the complex terrain in the agricultural field, we have developed the four-wheel drive and four-wheel steering robot chassis RMP-WL300. Each wheel is equipped with an independent dual motor, enabling independent and precise control of the speed and torque of each wheel.

Four-wheel independent steering (4WS)

Each wheel of the chassis can steer independently without affecting the others. It supports one-click switching between three movement modes: lateral, Ackermann steering, and in-place turning. Thanks to its extremely small turning radius and ability to turn around on the spot, the four wheel drive chassis has excellent passability in narrow ridges and between orchard rows, and also avoids crushing crops.

Four-wheel independent drive (4WD)

On slopes, clay, and slippery surfaces, each wheel has independent speed control and can dynamically distribute torque according to the ground adhesion to ensure smooth driving and reduce slippage. The four wheel drive chassis breaks through the limitation of traditional differential chassis that can only turn in arcs, greatly improving maneuverability in narrow or complex environments.

Not just a chassis, but a modular mobile platform

Adjustable wheel track and wheelbase

The four wheel drive chassis adopts an adjustable wheel track and wheelbase structure to solve the problem of non-standard row spacing that is common in agricultural operations. It can quickly adapt to different row spacings in different planting areas, and also supports parameter customization to meet the needs of specific scenarios.

Excellent expandability

It can be equipped with a variety of agricultural implements such as sprayers, fertilizer applicators, transport trailers, seeders, and weeders. One four wheel drive chassis can cover a variety of agricultural tasks, greatly reducing equipment idle rate and investment costs.

Built-in VCU + CAN communication protocol

The agricultural robot chassis has a reserved standard interface, supporting multiple navigation methods such as Beidou, laser, and follow.

This means that the RMP-WL300 is not only a four wheel drive chassis, but also an open robot development platform that supports custom programming.

Application value

The four-wheel drive, four-wheel steering robot chassis RMP-WL300 significantly improves the maneuverability, flexibility, and stability of agricultural robots on uneven terrain. It can operate smoothly on steep slopes, wetlands, or narrow ridges, making it suitable for agricultural processes that require high adaptability to terrain, such as laser weeding, precision spraying, and inter-row transportation.

If you are facing the following problems:

Side slip on slopes, bogging down in wetlands, crop damage in narrow rows — existing agricultural machinery struggles to adapt to complex terrains.

Develop spraying and laser-weeding robots — a modular outdoor robot platform that supports secondary development is required.

The lack of a flexible four-wheel drive and four-wheel steering chassis — The project's hardware bottlenecks are difficult to overcome.

We can help you solve this.

The four wheel drive chassis RMP-WL300 has undergone multiple iterations and upgrades and has been tested in real-world agricultural applications. Please feel free to contact us for detailed specifications or technical support.
