D7 vs Cruzr S2: Key Differences

Both robots share similar dimensions and weight ranges, with the D7 measuring 170cm in height and the Cruzr S2 slightly taller at 176cm. The D7 features a semi-humanoid upper body combined with an omnidirectional mobile base, while the Cruzr S2 has a symmetrical body design with a wheeled humanoid form and bidirectional bending capability. Both are built for industrial robustness but differ in mobility form factors and manipulation design.

The D7 employs balance-assisted walking and visual SLAM combined with LiDAR mapping to navigate complex environments autonomously or via teleoperation. The Cruzr S2 uses a visual-laser fusion navigation system integrating RGB cameras and LiDAR for precise path optimization and obstacle avoidance. It achieves a higher consistent speed of 2 m/s with wheeled mobility, favoring flat indoor terrains, whereas the D7's walking speed ranges from 1.5 to 3 m/s, offering potentially greater terrain adaptability.

Both robots are equipped with an extensive sensor suite including RGB and depth cameras, LiDAR, IMU, force/torque sensors, gyroscopes, accelerometers, and joint encoders. This sensor parity supports advanced perception for manipulation, navigation, and safety. The Cruzr S2 additionally leverages multi-robot orchestration features and real-time environment mapping, enhancing its operational reliability in crowded or dynamic industrial settings.

The D7 integrates learned behaviors and autonomous control via a Linux-based OS with ROS 2 support and a Python SDK, enabling adaptive task execution and teleoperation. Similarly, the Cruzr S2 supports teleoperation, autonomy, and learned behaviors with a comparable software stack. Its AI is augmented by a sim-to-real embodied intelligent data system enabling sub-millimeter manipulation precision and learning-based motion control for complex terrain navigation.

Both robots feature batteries rated for 3 to 5 years of service life. The D7 uses a 3-5 kWh, 48V LiPo battery pack providing 3-5 hours of runtime with 2-4 hours charging time. The Cruzr S2 emphasizes continuous operation with capabilities for autonomous battery swapping, reducing downtime and supporting long shifts. This feature enhances Cruzr S2’s suitability for 24/7 industrial labor without human intervention.

The D7 is suited for versatile applications such as manufacturing, research, logistics, infrastructure inspection, and remote operations, leveraging its dexterous arms and walking mobility. The Cruzr S2 targets controlled indoor industrial environments like factories and warehouses, where its wheeled mobility and speed optimize workflow efficiency. Both platforms support similar use cases but differ in terrain adaptability and integration focus.

The D7 features dual bionic arms with 30 degrees of freedom (expandable to 50) capable of carrying 15-25 kg per arm, supporting complex manipulation tasks. The Cruzr S2 is equipped with gen-4 dexterous hands capable of sub-millimeter manipulation and can handle payloads up to 15 kg across a 0-1.8m workspace with a 0-40cm lifting range. This makes Cruzr S2 highly precise in grasping and assembly operations.

Both robots run on Linux-based operating systems and support ROS 2 along with Python SDKs, facilitating integration and customization. The Cruzr S2 benefits from UBTECH’s Brain Network 2.0, which enables advanced multi-robot orchestration and ecosystem integration with industrial partners. The D7’s software emphasizes adaptable autonomous behaviors and teleoperation interfaces suitable for diverse research and industrial applications.

Both platforms incorporate force limiting, collision detection, emergency stops, and redundant sensors to ensure operational safety. The Cruzr S2 also highlights human-robot collaboration safety through learning-based motion control and self-balanced walking on complex terrain. These features contribute to safe deployment in environments requiring close human interaction.

Both the D7 and Cruzr S2 fall within a similar estimated price range of $50,000 to $150,000. This pricing reflects their advanced capabilities and industrial-grade design. Choice between them may depend on specific operational needs such as terrain adaptability, precision manipulation, or ecosystem integration rather than cost differences.
