Hybrid Wheel-Leg Mobility System – Unitree Go2W-U4 merges the strengths of both wheels and legs, offering the ability to travel at high speed on smooth roads with its 7-inch pneumatic tires, while still using leg-assisted motion to tackle curbs, stairs, and rugged terrain. This dual capability gives it a clear advantage over standard wheeled robots.

Flagship-Grade 3D LiDAR (Hesai XT16) – Unlike the base versions, the U4 comes equipped with a high-performance 3D LiDAR XT16 sensor. This provides wide-area, high-density environmental scanning, enabling the robot to perceive its surroundings with incredible accuracy. It improves mapping, path planning, and obstacle avoidance, especially in complex or cluttered environments.

Unmatched Obstacle Conquering Ability – Built for challenging missions, the U4 can scale obstacles up to 70 cm in height—something most wheeled robots cannot achieve. Unitree Go2W-U4 is ideal for industrial sites, rescue environments, and outdoor patrols where it must adapt to uneven ground and barriers.

Robust Payload Support – With a carrying capacity of up to 8 kg, the U4 can transport external sensors, cameras, measurement devices, or custom research equipment. This makes it highly versatile for both industrial inspection tasks and academic research applications.

High-Definition Visual Awareness – Dual wide-angle HD cameras (1080p) give the robot excellent vision capabilities, streaming real-time footage with very low latency (~180 ms). Operators get clear situational awareness during remote missions, inspections, or surveillance work.

Fast Traversal Speeds – In wheeled mode, the Go2W U4 can reach speeds of up to 2.5 m/s, allowing it to quickly cover large areas such as campuses, factories, or open outdoor fields. When navigating obstacles, it seamlessly slows down to a more controlled leg-based gait.

Long-Lasting Endurance – Equipped with a powerful rechargeable battery, the U4 delivers 2–4 hours of operational runtime per charge. This endurance makes it well-suited for patrols, inspection rounds, or extended research sessions without frequent recharging.

Dual-Layer Communication System – To ensure stable connectivity, Unitree Go2W-U4 uses 5.8 GHz low-latency telemetry as its primary channel, while also supporting 4G All-NetCom backup. This dual system guarantees uninterrupted control and monitoring, even in areas with connectivity challenges.

Expandable & Modular Design – The U4 is built with modularity in mind, supporting add-ons such as the Unitree D1 robotic arm, extra sensors, and custom modules. Researchers and industries can tailor it to specialized applications, from environmental monitoring to automated inspections.

Always Improving with OTA Updates – The platform supports over-the-air firmware updates, meaning new features, performance enhancements, and AI improvements can be installed remotely. This ensures that the robot grows smarter and more capable over time.

Durable & Portable Construction – Despite its advanced hardware, the Unitree Go2W-U4 maintains a compact footprint and robust build. Its aluminum alloy frame and engineering plastics make it strong enough for outdoor deployment while keeping it lightweight for transport and quick deployment.

Intuitive Handheld Controller – Every U4 comes with a dual-joystick handheld controller that gives operators precise, responsive control. Its ergonomic design and extended range make it practical for training, demonstrations, and live missions.
