4 Wheel Outdoor Robot Base

4 wheel outdoor robot base is a four-wheel remote-controlled robot chassis specifically designed for heavy-duty operations. Featuring independent four-wheel drive and a direct-drive shaft transmission structure, it boasts a stable payload capacity of 200kg despite its own weight of 100kg. Paired with high-grip herringbone-pattern pneumatic tires (including inner tubes), it is particularly suited for long-term operation in harsh conditions such as mud, water, and dust. This chassis finds broad application in agricultural orchard pest control, greenhouse material transport, industrial facility inspections, and emergency relief supply delivery. It excels particularly on complex terrains, including muddy fields, gravel roads, and slippery slopes.

Transmission System

Features a four-wheel independent drive with a direct-drive shaft transmission design. The motor output shaft is rigidly connected to the wheels via universal joints, minimizing risks of belt slippage and chain derailment. This design is particularly suited for harsh conditions such as mud, water, and dust, enabling low-maintenance operation that requires no tensioning or lubrication.

4 wheel outdoor robot base employs a mechanical architecture featuring four-wheel independent drive coupled with direct-drive shaft transmission, forming a highly integrated rigid power transmission system. The transmission system utilizes fully sealed bearings with dust and mud protection design, while critical connection points are equipped with multiple sealing rings to effectively block the intrusion of external contaminants.

Each motor's output shaft is rigidly connected to the wheels via high-precision universal joints. The power transmission path from motor to wheel is straightforward and direct, eliminating intermediate conversion components such as belts, chains, or gear sets. This fundamentally eliminates failure risks common in traditional transmission methods, including slippage, gear skipping, and breakage.

When outdoor robot bases traverse muddy, waterlogged, or dusty environments, mud and debris cannot penetrate the sealed shaft system, preventing issues like belt slippage due to mud buildup or chain jamming and corrosion. Simultaneously, the rigid connection ensures complete transmission of motor torque, enabling precise power response even when starting on slippery slopes or soft ground. This eliminates insufficient driving force caused by transmission losses.

Heavy Load-to-Weight Ratio

With a curb weight of just 100kg, it can stably carry a 200kg payload (static), achieving a 2:1 load-to-weight ratio. The low-center-of-gravity frame design ensures stable parking and driving on 30° inclines even when fully loaded, balancing high load capacity with platform maneuverability.

Tire Configuration

Standard herringbone tread pneumatic tires (with inner tubes) provide strong traction in both forward and reverse directions, effectively handling complex terrain such as slippery mud, gravel, and grass. The built-in inner tube structure allows low-speed operation even after punctures, enabling operators to maneuver the equipment out of hazardous areas or muddy terrain before repairing or replacing the tire. This prevents the equipment from becoming stranded in hard-to-reach work sites due to sudden deflation.

Expansion and Integration Capabilities

Features dual 48V/12V external power supply interfaces, standard CAN bus support, and PWM/RS485 control capabilities for rapid integration of peripherals such as LiDAR, robotic arms, and gimbal cameras. Provides a comprehensive SDK and control protocols, supporting rapid development within ROS systems to accommodate customized requirements across diverse scenarios including inspection, crop protection, and rescue operations.

Tailored Optimization for Typical Scenarios

Specifically engineered for agricultural orchards, vegetable greenhouses, industrial sites, emergency response operations, and similar environments, it delivers exceptional maneuverability across challenging terrains including muddy fields, paddy field edges, gravel roads, and slippery slopes. Weighing just 100kg, it facilitates manual handling and vehicle transport, meeting “last-mile” deployment requirements.

1. Complex Terrain Environments

Soft, slippery surfaces like muddy fields, paddy field edges, and marsh borders (herringbone tread provides strong traction and anti-sink capability)

Unpaved surfaces such as gravel roads, rocky slopes, and dirt paths

Slippery slopes up to 30° and transition zones at stair edges (low center of gravity + four-wheel independent drive ensure stability)

Narrow spaces like vegetable greenhouses, orchard rows, and landscaped paths.

2. Agricultural Operations

Open-air vegetable farms, tropical greenhouses, orchard crop protection tasks

Greenhouse material transport (fertilizer, harvest baskets, etc.; 200kg load capacity supports bulk transport)

Mild chemical exposure environments involving frequent contact with pesticide sprays and liquid fertilizers.

3. Industrial and Specialized Operations

Low-to-medium speed inspection environments in factory grounds, warehouses, and solar power plants

Material delivery and reconnaissance equipment deployment in disaster zones (earthquake and flood periphery areas)

Long-term field deployment in coastal high-humidity environments with significant diurnal temperature variations causing condensation
