Walker S1 vs Green: Key Differences

Both Walker S1 and Green share identical dimensions (170cm x 55cm x 38cm) and weight ranges (50-80 kg), reflecting similar humanoid form factors optimized for balance and stability. Their build quality supports bipedal locomotion with force/torque sensors and joint encoders to maintain precise movements. Green additionally offers color variants (white, gray, black), which may reflect customization options not specified for Walker S1.

Each robot achieves walking speeds between 1.5-3 m/s using balance-assisted walking combined with Visual SLAM and LiDAR mapping for navigation. Both platforms support autonomous and teleoperated control modes. Walker S1 has documented limitations in uneven terrain and cluttered environments, whereas Green’s motion control is supplemented by real-time balance adjustments and advanced AI for dynamic interaction.

Walker S1 and Green both integrate a comprehensive array of sensors including RGB and depth cameras, LiDAR, IMU, gyroscopes, accelerometers, force/torque sensors, and joint encoders. This sensor fusion facilitates environment mapping, obstacle avoidance, and balance maintenance. Green’s sensor data supports AI-driven environmental awareness, enhancing perception for complex task execution.

Walker S1 supports learned behaviors and autonomous operation primarily through ROS 2 and a Linux-based OS, focusing on task adaptability in industrial scenarios. Green incorporates Sberbank’s GigaChat AI system, enabling natural language interaction, continuous learning, and more advanced autonomous decision-making. This AI integration allows Green to perform gestures, interact socially, and respond dynamically to voice commands.

Walker S1’s battery specifications are not publicly disclosed, limiting direct comparison. In contrast, Green provides detailed battery data including a runtime of 3-5 hours per charge, 2-4 hours charging time, and an overall battery lifespan of 3-5 years with a 3-5 kWh, 48V LiPo battery pack, indicating a focus on long-term operational efficiency.

Both robots are designed for manufacturing, research, logistics, infrastructure inspection, and remote operations, supporting a range of industrial and service roles. Walker S1’s design emphasizes improving ergonomics and safety in manufacturing, while Green’s AI-driven interface and communication abilities enhance its suitability for interactive and dynamic environments requiring continuous learning.

Walker S1 and Green both run on Linux-based operating systems with ROS 2 support and provide Python SDKs, facilitating integration and programming flexibility. Green’s additional AI platform (GigaChat) extends its software capabilities to include conversational AI and advanced task automation, which may offer a richer ecosystem for developing interactive applications.

Both robots incorporate force limiting, collision detection, emergency stop functions, and redundant sensors to ensure safe operation around humans and in industrial settings. Walker S1, however, has noted challenges regarding safety in human-robot interaction, especially with unexpected impacts from the front or rear, suggesting areas for future improvement.
