D1 Ultra Quadruped Robot: Swift, Agile, and Unstoppable

The D1 Ultra is a compact, high-performance quadruped robot engineered for industrial, research, educational, and security applications. Powered by advanced reinforcement learning algorithms, it can autonomously adapt to complex environments, maintain balance, and navigate challenging terrain with remarkable agility. Combining rugged construction, powerful motors, and an open development ecosystem, D1 Ultra delivers professional-grade robotic mobility in a highly portable platform.

Limitless Application Scenarios

From securing perimeters to advancing academia. Thanks to its robust build, intelligent algorithms, and payload flexibility, it is perfectly suited for complex security patrols, interactive entertainment, and providing a hands-on, high-performance platform for scientific research and education.

Rugged All-Weather Architecture

Engineered to thrive in the harshest environments. The D1 Ultra boasts a high-standard structural design with advanced material engineering, including vacuum press-formed aluminum alloy shafts and hermetically sealed, anti-corrosive core components. With enhanced dust and water resistance, it maintains stable, continuous operation across damp, muddy, splashing, and sandy terrains.

Reinforcement Learning Mobility

Powered by reinforcement learning (RL), D1 Ultra continuously adapts its gait to different surfaces and obstacles. Its intelligent locomotion system provides self-balancing, anti-tipping behavior, and disturbance rejection for stable operation across unpredictable terrain.

All-Terrain Performance

Designed for challenging environments, the robot can run at speeds up to 3.7 m/s, climb slopes reaching 30° (up to 40° maximum), jump up to 35 cm, and continuously climb stairs up to 16 cm high. These capabilities make it ideal for both indoor and outdoor deployment.

High-Torque Motor System

Each joint is powered by high-performance motors capable of delivering up to 48 N·m of peak torque. The motors are engineered for impact resistance, heavy-load tasks, and demanding operational conditions while maintaining smooth and stable movement.

Calibration-Free Deployment

Dual-encoder motor controllers eliminate the need for zero-position calibration. Simply power on the robot and begin operating immediately, reducing setup time and improving operational efficiency.

Open Development Ecosystem

D1 Ultra supports extensive customization through standardized interfaces and an open SDK. Developers can integrate sensors, communication modules, and specialized payloads while building custom applications and workflows.

Advanced Sensor & Module Compatibility

The platform supports LiDAR systems, depth cameras, RTK positioning modules, image transmission modules, and 4G/5G communication solutions. This flexibility allows deployment across research, automation, mapping, and inspection projects.

Simulation & Robotics Research Ready

Support for URDF modeling enables seamless simulation in professional robotics platforms such as Isaac Sim and MuJoCo. Developers can test and optimize robotic behaviors virtually before real-world deployment.
