D7 by Pudu vs Green by Sberbank Robots

Both D7 and Green share identical physical dimensions of 170cm height, 55cm width, and 38cm depth, with weight ranges between 50 to 80 kg. Their humanoid form factors and construction support bipedal walking and manipulation tasks. The build quality reflects their industrial and research orientation, with robust sensors and actuators integrated for balance and dexterity.

Both robots achieve walking speeds between 1.5 to 3 meters per second, utilizing visual SLAM, LiDAR mapping, and balance-assisted walking for navigation. This allows them to operate autonomously or under teleoperation in complex environments, including manufacturing floors and infrastructure sites. Their locomotion systems enable stable movement over varied terrains.

D7 and Green are equipped with comprehensive sensor suites including RGB and depth cameras, LiDAR, IMU, force/torque sensors, gyroscopes, accelerometers, and joint encoders. These sensors support precise environmental perception, object recognition, and real-time balance management, essential for autonomous operation and manipulation.

While both support autonomous and teleoperated control with learned behaviors, Green integrates Sberbank’s GigaChat AI system, which enables advanced natural language interaction and continuous learning. The D7 focuses on adaptable autonomous behaviors suitable for diverse industrial tasks but does not explicitly incorporate a proprietary conversational AI system.

Each robot features a battery lifespan of 3 to 5 years with charging times estimated between 2 to 4 hours. Both utilize efficient power management systems capable of supporting extended operation cycles in industrial or research settings.

Both robots are designed for manufacturing, research, logistics, infrastructure inspection, and remote operation tasks. The D7 emphasizes dexterous manipulation and balance for complex handling operations, while Green leverages AI-driven interaction and continuous learning to enhance automation in service and industrial environments.

D7 and Green run on Linux-based operating systems with ROS 2 support and provide Python SDKs for customization. Green’s software is enhanced by Sberbank’s AI platform, enabling integration of conversational AI, whereas D7’s software focuses on flexible autonomy and teleoperation suited to varied robotic tasks.

Both robots incorporate force limiting, collision detection, emergency stop functions, and redundant sensors to ensure operational safety. These features are critical to preventing accidents during autonomous or teleoperated activities in dynamic industrial environments.
