By delivering high-speed, stable handling, seamless adaptation across diverse scenarios, and minimal operational costs, we address the pain points of efficiency loss and operational disruptions caused by unstable chassis, poor adaptability, and frequent maintenance in complex environments.


What is Ackermann steering?

It ensures all wheels roll around the same instantaneous center of steering (ICC) during turns, preventing tire skidding (reducing tire wear, improving control precision, and saving energy).

Outdoor Robot Platform

Implementation Method:

The inner front wheel (steering wheel) has a greater steering angle than the outer front wheel.

The steering angle difference between the two front wheels is precisely controlled via a steering trapezoidal linkage mechanism (or electronic control in modern robots).

The rear wheels are typically fixed drive wheels (or differential drive) and do not participate in steering.

Why do robots use Ackermann steering?

Zero-slip turning: Ideal for soft outdoor surfaces (grass, sand, mud) to prevent positioning drift caused by sideways slippage in differential-drive robots.

High path-tracking accuracy: Suitable for scenarios requiring fixed-path operation, such as farmland inspections, logistics transportation, and surveying.

Low energy consumption and wear: Pure tire rolling reduces friction, extending endurance and tire lifespan (compared to Mecanum wheels/omnidirectional wheels).

High-speed stability: More stable than differential steering at high speeds (>2m/s), minimizing tail-out (e.g., security patrol robots).

Eight-Layer Security Protection System: This comprehensive defense features dual hardware and software safeguards that operate simultaneously without conflict. Even under the harshest conditions—heavy rain, dust, high temperatures, or electromagnetic interference—it provides you and your field personnel with a true last line of defense.

Communications BCC Protection

Even in environments with extremely strong electromagnetic interference, such as ports, steel mills, and mining areas, critical commands like forward movement, steering, and braking are guaranteed to remain 100% tamper-proof.

Overtemperature Protection

The motor, driver, battery, and key chips on the power board all incorporate independent NTC temperature sensors for real-time temperature monitoring.

Short Circuit Protection

Whether it's wiring harness insulation failure causing short circuits in rainy weather, salt spray corrosion at ports leading to connector breakdown, or forklift collisions severing cables—power is cut off before sparks appear, completely eliminating the possibility of “chassis smoke and fire.”

Emergency Stop Protection

Both the robot body and remote controller feature a red emergency stop mushroom-head button. Pressing it once physically hard-disconnects the main contactor, completely cutting power to the vehicle's battery within 0.1 seconds. All motors lock up and lose power, achieving a braking distance of ≤30cm. This ensures that in any hazardous situation, the robot can be brought to a complete stop instantly.

Overload Protection

The outdoor 2wd robot platform continuously monitors the current of each motor phase and the total input current. When the load exceeds 120% of the rated capacity for over 5 seconds, the system automatically reduces speed and limits power output. If the load exceeds 150%, an alarm is triggered immediately, and the system gradually stops to prevent prolonged overload conditions that could cause motor stalling, driver board failure, or battery over-discharge.

Steering Limit Protection

The steering motor incorporates a high-precision absolute encoder + dual mechanical hard stops.

Communication Heartbeat Protection

If the robot fails to detect the remote controller's signal for three consecutive times (indicating communication failure or disconnection), it immediately enters “Safety Mode”: - Automatically level the ground - Decelerate in place - Stop completely - Engage the brake lock This completely eliminates the risk of runaway accidents.

Communication Timeout Protection

Each key command (such as move forward, turn, or raise/lower) has a maximum response time limit (default 1 second).

Outdoor Robot Platform

1. Outdoor Inspection Robots: In scenarios such as power line inspections, photovoltaic power plant maintenance, and orchard monitoring, robots must operate stably over extended periods on unstructured terrain (e.g., muddy ground, gravel roads, inclined ramps). Ackermann steering significantly reduces the risk of tire sinking in soft ground through its zero-side-slip turning capability.

 

2. Logistics AGVs: Large-scale outdoor warehouse transfer scenarios demand AGVs with both high load capacity (1-10 tons) and precise docking accuracy (error <±5mm). The outdoor 2wd robot platform efficiently converts power into traction through its rigid frame and independently driven rear wheels.

 

3. Research & Education Platforms: Universities and research institutions widely adopt Ackermann chassis as teaching vehicles for autonomous driving education.

 

4. Special-Purpose Robots: High-risk scenarios like fire reconnaissance and nuclear power plant inspections impose stringent demands on robots' extreme environment adaptability. Crawler structures easily get stuck in debris, while omnidirectional wheels slip on rubble surfaces. The outdoor 2wd robot platform, featuring large-diameter off-road tires and pure rolling steering, maintains trajectory precision even on 30° rubble slopes.

 

5. Low-Speed Autonomous Vehicles: Level 4 autonomous vehicles for campus delivery and scenic area navigation operate in mixed pedestrian-vehicle environments.
