Walker S1 (UBTECH) vs AgiBot G2 (AgiBot)

Walker S1 measures 170cm x 55cm x 38cm and weighs 50-80 kg, offering a specified compact frame suitable for varied environments. AgiBot G2 is 175 cm tall with typical humanoid proportions of ~50 cm width and ~40 cm depth at 55 kg, providing similar build but slightly taller stature. Both employ robust humanoid designs, though Walker S1 discloses precise dimensions while AgiBot G2 relies on estimates.

Walker S1 achieves 1.5-3 m/s walking speed using Visual SLAM, LiDAR mapping, and balance-assisted walking for reliable navigation. AgiBot G2 reaches 7 km/h (~1.94 m/s) with advanced spatial perception and obstacle avoidance, likely SLAM-based. Walker S1 emphasizes speed range and explicit mapping, while AgiBot G2 prioritizes integrated perception for dynamic movement.

Walker S1 integrates RGB cameras, depth camera, LiDAR, IMU, force/torque sensors, gyroscope, accelerometer, and joint encoders for comprehensive perception. AgiBot G2 features high-precision torque sensors, 360-degree spatial perception, cameras, force sensors, and environmental sensors. Walker S1 lists specific sensor types, contrasting AgiBot G2's broader spatial system without detailed breakdowns.

Walker S1 supports teleoperation, autonomous control, and learned behaviors via Linux-based OS and Python SDK. AgiBot G2 employs AI autonomous control, remote teleoperation, multimodal voice interaction, and reinforcement learning on proprietary AI OS. AgiBot G2 highlights voice and learning integration, while Walker S1 focuses on developer-friendly control options.

Neither robot publicly discloses exact battery specifications, with Walker S1 noting it as not available and AgiBot G2 estimating 3-5 years for industrial lithium batteries. Both lack runtime or capacity details, limiting direct efficiency comparisons. Industrial designs suggest comparable power needs for sustained operations.

Walker S1 fits manufacturing, research, logistics, infrastructure inspection, and remote operations with versatile navigation and control. AgiBot G2 targets auto parts production, precision manufacturing, logistics sorting, guided tours, and collaborative tasks via spatial perception and voice interaction. Walker S1 leans toward inspection and research, while AgiBot G2 emphasizes production and tours.

Walker S1 runs Linux-based OS with ROS 2 support and Python SDK for broad compatibility. AgiBot G2 uses proprietary AI OS, likely Linux-based, with reinforcement learning and simulation support. Walker S1 offers open standards, contrasting AgiBot G2's integrated AI focus.

Walker S1 includes force limiting, collision detection, emergency stop, and redundant sensors. AgiBot G2 provides emergency stop, real-time force sensing, obstacle avoidance, and impedance control. Both prioritize collision and force management, with Walker S1 adding redundancy.
