China’s Lynx M20S Robot Demonstrates Endurance in Extreme Cold and Rugged Terrain

DEEP Robotics has introduced the Lynx M20S, a wheeled-legged robot engineered to perform industrial tasks in demanding environments characterized by complex terrain and harsh conditions.

The M20S model offers enhancements over its predecessor, the M20, including increased payload capacity, improved mobility, greater durability, and extended operational endurance, establishing a new standard for industry-grade wheeled-legged robots.

Designed to excel in all-terrain scenarios, the Lynx M20S supports diverse inspection, logistics, and field operations where adaptability and reliability are essential.

Recently, DEEP Robotics released footage of its DR02 humanoid robot navigating difficult terrain, ascending stairs, and transporting equipment, highlighting its suitability for industrial and hazardous environment tasks.

Mastering rough terrain

The Lynx M20, a wheeled-legged robot, is tailored for industrial applications in challenging and hazardous environments. DEEP Robotics describes it as the first wheeled-legged robot worldwide designed specifically for demanding field operations such as power inspection, emergency response, logistics, and scientific exploration.

The latest demonstration video showcases the Lynx M20S operating in some of the most demanding natural settings. The footage captures the robot traversing rugged mountain landscapes, crossing icy rivers up to 31.5 inches (80 centimeters) deep, and functioning in temperatures as low as -22°F (-30°C).

In addition, the Lynx M20S climbs steep slopes of up to 45 degrees and maneuvers over rocky, uneven ground that would challenge traditional mobile robots. It maintains stability and mobility at altitudes approaching 17,000 feet (5,177 meters) while performing its tasks in severe outdoor conditions. The video emphasizes the robot’s unique combination of wheeled speed and legged agility, enabling it to overcome obstacles, extreme weather, and difficult terrain.

According to DEEP Robotics, the Lynx M20S is intended for industrial inspections, emergency response, and field operations, demonstrating how advanced robotic mobility can extend autonomous capabilities into locations that are often inaccessible or dangerous for human workers.

Next-gen field robot

Weighing 77 pounds (35 kilograms), the M20S merges the speed advantages of wheeled movement with the versatility of legged locomotion. It can navigate narrow passages with clearances as tight as 50 centimeters, ascend stairs up to 25 centimeters high, surmount obstacles reaching 80 centimeters, and handle slopes of up to 45 degrees. The robot is built to operate on rugged mountain paths, muddy wetlands, tunnels, pipelines, and areas affected by disasters.

The M20S supports a payload capacity of 33 pounds (15 kilograms) and can carry a maximum load of 110 pounds (50 kilograms). It achieves up to three hours of operation or 9 miles (15 kilometers) of travel on a single charge when unloaded. Carrying a 33-pound (15-kilogram) payload reduces its endurance to 2.5 hours and 7.4 miles (12 kilometers). Laboratory tests have recorded a top speed of 5 meters per second and an operating speed of 2 meters per second.

Equipped with dual 96-line LiDAR sensors, the robot offers a 360-degree horizontal and 90-degree vertical field of view for perception and navigation, supplemented by wide-angle cameras and omnidirectional obstacle avoidance. The platform is rated IP66 for protection against harsh environments and operates within a temperature range from -4°F (-20°C) to 131°F (55°C). Additional features include hot-swappable batteries, bidirectional lighting, over-the-air updates, and modular expansion capabilities.

To enhance operational endurance, DEEP Robotics increased the Lynx M20S’s single-charge runtime by between 17 and 67 percent and incorporated dual hot-swappable batteries. These upgrades address the high energy demands of wheeled-legged locomotion and support longer, uninterrupted missions.
