Innovative Electromechanical Wheel Transforming UGV Capabilities
Overview of the AZAK S26 Wheel
US-based technology company AZAK has introduced a groundbreaking electrically powered wheel designed specifically for use in autonomous unmanned ground vehicles (UGVs). The emerging technology aims to enhance operational effectiveness in diverse environments.
Key Features and Benefits
Comprehensive Integration
According to Ben Meager, CEO of AZAK and the wheel’s inventor, each wheel incorporates all necessary components for electric vehicle operation. These components include:
- Motor
- Motor Controller
- Gearbox
- AZAK Control System
- Battery Management System
- Battery
All components are strategically positioned beneath the wheel’s center, resulting in a remarkably low center of gravity. This design augments vehicle stability and capability.
Performance Metrics
The AZAK S26 wheel is characterized by:
- Height: 26 inches
- Width: 8 inches
- Weight: 86 lbs
- Top Speed: 12 mph
- Torque: 147 lb-ft (588 lb-ft for a four-wheel configuration)
- Payload Capacity: Up to 4,000 lbs (1,800 kg)
Its low center of gravity allows the vehicle to maneuver over challenging terrain, ascend obstacles up to twice its height, and negotiate gradients of up to 137% while carrying heavy loads.
Enhanced Maneuverability and Control
The AZAK S26’s design ensures effective power transfer to the ground, which enhances both acceleration and efficiency. Importantly, the vehicle maintains cornering agility comparable to a race car. Control options for UGVs employing these wheels can be:
- Wireless
- Tethered
- Autonomous
Military Applications and Future Prospects
The AZAK S26 wheel is already in limited operational use, gaining traction among branches of the US military. Its official launch in Europe occurred during the Defence and Security Equipment International (DSEI) 2025 exhibition held in September.
This technological advancement opens up extensive opportunities for expanding the capabilities of unmanned ground vehicles, potentially influencing military and civilian applications alike. The integration of such innovative solutions into defense readiness demonstrates the sector’s commitment to advancing operational effectiveness in complex environments.
