D7 by Pudu vs Green by Sberbank

These are very different machines. D7 is a 165 cm, 45 kg semi-humanoid on wheels, while Green is a 180 cm, 75 kg humanoid that walks on two legs. Green has more joints (41 against D7's 30), and 12 of them are finger joints, giving it fuller hands than D7's standard grippers. Green reaches 0.9 m/s. Pudu D7's mobility type is wheeled-based. Green's mobility type is legged. Green's control method is listed as autonomous, voice commands. Pudu D7 is listed as semi-autonomous to fully autonomous.

D7 is much faster on flat floors, rolling at up to 2 m/s against Green's 0.9 m/s walking speed. Its omnidirectional base suits shops, offices and hotels with smooth floors and lifts. Green's legs let it move like a person, and it navigates unfamiliar indoor spaces and avoids obstacles on its own. Pudu D7 has 30 degrees of freedom, carries 10 kg and can deadlift 50 kg. Green has 41 degrees of freedom. Pudu D7 stands 165 cm tall and weighs 45 kg. Green stands 180 cm tall and weighs 75 kg.

Green uses eight RGB cameras and two LiDARs for vision, with inertial sensors for balance and force-torque sensors in its fingertips. D7 relies on its perception system for navigation, elevator use and item handling in service settings. For fine manipulation, Green's fingertip force sensing is the notable extra. Green's sensors include 8 RGB cameras, 2 LiDARs and inertial sensors. Pudu D7 runs for more than 8 hours per charge. Pudu D7 reaches 2 m/s. Per the record, Pudu D7 has 30 degrees of freedom, carries 10 kg and can deadlift 50 kg. Per the record, Green has 41 degrees of freedom.

D7's embedded AI handles autonomous planning, perception and adaptive execution for service routines. Green adds conversation: it talks and follows voice commands through Sber's GigaChat, and its Green-VLA model (about 1.3 billion parameters, open weights) turns vision into hand movements. Green can also spot and correct its own mistakes. Per the record, Pudu D7 is listed as semi-autonomous to fully autonomous. Per the record, Green's control method is listed as autonomous, voice commands. For reference, Pudu D7 has 30 degrees of freedom, carries 10 kg and can deadlift 50 kg. For reference, Green has 41 degrees of freedom.

D7 is the clear winner on endurance, with Pudu quoting more than eight hours of continuous work from a battery above 1 kWh. Sber has published only that Green uses a 48 V battery, with no runtime or charging time yet. Per the record, Pudu D7 stands 165 cm tall and weighs 45 kg. Per the record, Green stands 180 cm tall and weighs 75 kg. Per the record, Pudu D7 reaches 2 m/s. Per the record, Green reaches 0.9 m/s. Per the record, Pudu D7's mobility type is wheeled-based. Per the record, Green's mobility type is legged.

D7 fits service and commercial automation today: item transport, sorting and moving between floors by lift. Green is positioned for collecting items and stocking shelves, assembling and packing products, lab work with test tubes and bio samples, and room service and cleaning, with Sber running business pilots before a planned product line. For reference, Pudu D7 stands 165 cm tall and weighs 45 kg. For reference, Green stands 180 cm tall and weighs 75 kg. Per the record, Pudu D7 runs for more than 8 hours per charge.

D7 is built around Pudu's service-robot platform. Green's software is Sber's GigaChat plus the open-weight Green-VLA model, and Sber invites outside teams to train controllers for it through the Green Challenge simulator contest. Sber has not announced a public SDK. For reference, Green's control method is listed as autonomous, voice commands. For reference, Pudu D7 runs for more than 8 hours per charge. Per the record, Green's sensors include 8 RGB cameras, 2 LiDARs and inertial sensors. For reference, Pudu D7 reaches 2 m/s. For reference, Green reaches 0.9 m/s.

A wheeled base gives D7 a low, stable footprint in public spaces. Green relies on inertial and force sensors to keep its balance, steers around obstacles and can detect its own errors; Sber has not published safety certifications for it. Ask both makers for certification details before deploying near the public. For reference, Green's sensors include 8 RGB cameras, 2 LiDARs and inertial sensors. For reference, Pudu D7's mobility type is wheeled-based. For reference, Green's mobility type is legged. For reference, Pudu D7 is listed as semi-autonomous to fully autonomous.
