Walker S1 vs Cruzr S2: Key Differences

The Walker S1 is a bipedal humanoid with a height of 170 cm and a weight range of 50–80 kg, built for industrial environments. The Cruzr S2 is slightly taller at 176 cm and shares a similar weight range and footprint, but uses a wheeled base instead of legs. Both robots are constructed for durability in dynamic settings, but the Walker S1’s legged design prioritizes human-like movement, while the Cruzr S2’s wheeled form emphasizes stable, continuous rolling mobility.

The Walker S1 uses balance-assisted bipedal walking with Visual SLAM and LiDAR mapping for navigation in structured indoor environments. The Cruzr S2 employs visual-laser fusion navigation, combining camera and LiDAR data for precise localization and path planning on flat surfaces. While the Walker S1 can navigate stairs and uneven terrain typical of factories, the Cruzr S2 is optimized for smooth floors and service-oriented routes such as showrooms and logistics aisles.

Both robots are equipped with RGB cameras, depth cameras, LiDAR, IMU, force/torque sensors, gyroscopes, accelerometers, and joint encoders. These sensors support 3D environment mapping, obstacle detection, and dynamic balance control. The core perception stack for both includes Visual SLAM and LiDAR-based mapping, enabling autonomous navigation and interaction with objects in shared human spaces.

The Walker S1 supports teleoperation, autonomous operation, and learned behaviors, running on a Linux-based OS with ROS 2 and Python SDK support. The Cruzr S2 shares the same control modes and software stack, allowing similar levels of programmability and integration. Both robots can be networked via UBTECH’s Brain Network 2.0 and Co-Agent AI platform, enabling multi-robot coordination in industrial and service scenarios.

Public specifications for the Walker S1’s battery are not disclosed, but it is designed for continuous operation in factory settings with periodic manual charging or swapping. The Cruzr S2 is reported to have a battery life rated for 3–5 years under normal usage, reflecting its service-oriented, wheeled design. Neither robot’s exact runtime per charge is specified, but the Walker S1’s bipedal motion is likely more power-intensive than the Cruzr S2’s wheeled locomotion.

The Walker S1 is optimized for industrial manufacturing and logistics tasks such as assembly, sorting, and quality checks in smart factories. The Cruzr S2 is better suited for service and light industrial roles including guided tours, reception, and factory logistics on flat surfaces. Both can support research and remote operations, but the Walker S1 targets heavy-duty industrial automation, while the Cruzr S2 focuses on flexible, mobile service applications.

The Walker S1 is designed for high-payload industrial tasks, with a reported 15 kg payload capacity and a workspace extending from ground level to 1.8 meters. The Cruzr S2 is intended for lighter payloads typical of service and logistics, though its exact payload limit is not specified in the provided data. Both robots feature dexterous hands and force/torque sensing, but the Walker S1’s mechanical design emphasizes strength and reach for factory work.

Both the Walker S1 and Cruzr S2 run on a Linux-based operating system with ROS 2 support and a Python SDK, enabling standard robotics development workflows. They support teleoperation, autonomous navigation, and learned behaviors, and can be integrated into larger automation systems. Both are compatible with UBTECH’s Brain Network 2.0 and Co-Agent AI platform, allowing for multi-robot coordination and swarm intelligence in industrial deployments.

The Walker S1 is described as the most widely deployed industrial humanoid robot in factories, with installations in smart factories operated by major Chinese automakers including BYD, Geely, and Nio. In these deployments, it has reportedly improved sorting efficiency by up to 120% and reduced labor costs by 65%. The Cruzr S2 is positioned for broader service and logistics use, including factory assembly, logistics, and guided tours, and can be networked with other mobile platforms for integrated workflows.
