4 Wheel Smart Robot Chassis

The four-wheel drive and four-wheel steering chassis is a mobile robot chassis with four-wheel independent steering and four-wheel independent drive capabilities. Each wheel has an independent steering mechanism that can be freely adjusted. The robot chassis has a payload capacity of 200 kg and can carry various sensors, cameras, robotic arms, and other equipment to meet the needs of a variety of complex tasks. This payload capacity makes it widely applicable in many fields, such as inspection, firefighting, and transportation.

Parameter Table

Four-wheel independent steering (4WS): Each wheel is equipped with an independent steering mechanism that can precisely control the steering angle. This design unlocks a variety of highly flexible driving modes:

Zero-radius turning on the spot: By coordinating the steering angles of each wheel, the 4 wheel smart robot chassis can rotate 360° on the spot (with a turning radius of zero) around a fixed center point, greatly improving maneuverability and operational efficiency in narrow spaces (such as corridors and between shelves).

Lateral shift: All wheels turn synchronously to a direction perpendicular to the vehicle body (90°), enabling pure lateral movement without deviation, easily handling narrow scenarios where the passage width is only slightly greater than the vehicle body.

Diagonal travel in any direction: Precise adjustment of the steering angle combination of the four wheels enables diagonal travel in any direction, providing more flexible route planning capabilities.

Four-wheel independent drive (4WD): Each wheel is equipped with an independent drive motor, enabling precise and independent control of wheel speed. This design offers two key advantages:

Precise motion control: By precisely adjusting the speed difference between each wheel, it can perfectly match complex steering commands (such as turning in place or driving diagonally), ensuring highly accurate motion trajectories.

Terrain Adaptability: Independent drive enables each wheel to adaptively adjust torque output based on real-time ground conditions (such as slippery or rugged terrain), significantly enhancing maneuverability and stability on complex or low-friction surfaces.

Thanks to its powerful obstacle-crossing capabilities and high adaptability, the 4 wheel smart robot chassis can perform tasks in complex outdoor environments (under various terrain conditions), whether it be rugged mountains, muddy rainforests, or frozen polar regions, easily coping with complex outdoor geographical conditions.

1. Narrow and complex indoor environments

Ackermann steering robot chassis require a large turning radius, making them inefficient when navigating narrow corridors, doorways, and around furniture. In contrast, a four-wheel drive chassis can rotate 360 degrees in place and move laterally, enabling it to:

Precisely adjust its posture in confined spaces, such as aligning with workstations on a production line or picking items between shelves.

Quickly and efficiently complete tasks in environments requiring frequent turns or obstacle avoidance.

Provide navigation and delivery services in public areas such as hospitals, shopping malls, and office buildings without concerns about foot traffic or complex layouts.

2. Industrial environments requiring high-precision positioning and alignment

In the field of industrial automation, many tasks require smart robot chassis to place items precisely in designated locations or align them with specific machine interfaces. For example:

Automated warehousing and logistics: 4 wheel smart robot chassis need to retrieve goods from shelves and place them precisely on conveyor belts, or perform high-precision palletizing in narrow aisles.

Production line handling: Robot chassis need to transport parts to the assembly line and precisely coordinate with robotic arms or workers.

3. Variable or irregular ground conditions  

Traction and maneuverability: Each wheel is driven by an independent motor, enabling independent torque adjustment based on road conditions. This ensures better traction and stability when ascending or descending slopes, crossing small obstacles, or navigating slippery surfaces.

Adaptability: In some research or exploration tasks, robot chassis need to navigate uneven terrain such as sandy or gravelly surfaces. Four-wheel independent drive provides stronger propulsion power, reducing mobility issues caused by a single wheel slipping.
