How to Choose the Right Chassis for Agricultural Robot Development?

In the process of agricultural robots moving from blueprints to operational scenarios, developers often face a real dilemma: independent development requires overcoming robot chassis challenges from scratch.

Insufficient battery life: The algorithm is perfectly tuned, but the chassis battery life cannot meet the requirements.

Poor maneuverability: The robot gets stuck in complex terrain and needs to be lifted manually.

Insufficient load capacity: The design did not take into account the weight of the upper part. Once the agricultural implement was loaded, it exceeded the maximum load capacity.

The development of the chassis from scratch usually takes several months, but the testing window period for agricultural robots is much shorter than this duration. To avoid missing critical testing milestones, adopting an agricultural robot chassis that has been verified in the field becomes a more reliable and efficient solution. The RMP-WL300 wheeled chassis was specifically developed to meet this requirement.

Battery life – 6 hours, supports fast battery swapping

Agricultural operations usually require continuous operation for several hours without interruption. The RMP-WL300 wheeled chassis can achieve an empty-load endurance of up to 6 hours under typical field conditions, meeting most of the daytime operation requirements. With a full load, it can last for approximately 4 hours. 

Inside the battery compartment, there is a DC48V 30Ah lithium iron phosphate battery pack. It supports quick disassembly and replacement, significantly improving the efficiency of field operations.

Load capacity – Rated load of 300kg, capable of carrying various agricultural implements.

The rated load capacity of the wheeled chassis is 300kg. It also supports customized load capacity to meet the needs of various agricultural applications.

It can be equipped with various agricultural implements such as sprayers, fertilizer applicators, transport bins, seeders, and weeders, meeting the diverse operational needs of agricultural robots for sowing, fertilizing, spraying, and transportation, achieving multi-purpose functionality. This significantly improves equipment utilization and reduces procurement costs.

Obstacle clearance – 150mm obstacle clearance height, 20° climbing angle

The farmland has a complex topography, with field ridges, furrows, and slopes everywhere. The four wheel drive chassis has a 150mm obstacle clearance, enabling it to easily cross small field ridges and earthen mounds; It also supports climbing slopes of up to 20 degrees, ensuring stable passage on the slope without the need for any intermediate intervention.

Four-wheel drive with four-wheel steering + Adjustable wheel track and wheelbase

In addition to the above three points, the RMP-WL300 outdoor robot platform is equipped with four-wheel drive and four-wheel steering configuration, featuring a small turning radius and flexible turning, with strong maneuverability. Both the wheel track and wheelbase are adjustable, making it easy to adapt to different crop row spacings and operating widths.

Typical application scenarios

Seedling cultivation / Transplanting

Laser weeding

Spraying pesticides and fertilizing in the orchard

Unmanned transportation

Has your robot project also encountered issues with battery life or maneuverability? Have you repeatedly modified the chassis framework in an attempt to accommodate different row spacings?

The RMP-WL300 four wheel drive robot chassis offers a mature solution to these problems and has completed multiple rounds of field tests and iterations in real agricultural scenarios.

The robot chassis is not an additional component; rather, it is the "mobile base" of the entire machine, supporting the body, providing movement capabilities, and determining stability and maneuverability. The RMP-WL300 outdoor robot platform is based on the actual agricultural problems and provides a set of robot chassis solutions that can withstand the tests in the field.
