The Pudu D7 (stylized as PUDU D7) is a semi-humanoid robot developed by Pudu Robotics, a Shenzhen-based Chinese robotics company best known for its commercial service robots such as the BellaBot and KettyBot. Unveiled on September 19, 2024, the D7 is Pudu's first general-purpose embodied intelligent semi-humanoid robot. It combines a human-like upper body with bionic arms and a fully omnidirectional wheeled chassis, representing Pudu Robotics' initial entry into the humanoid robotics sector [1].
Standing 165 cm tall and weighing 45 kg, the D7 features 30 degrees of freedom (expandable to 50 with a dexterous hand attachment), bionic arms with a 65 cm reach and 10 kg payload capacity, and endpoint repeatability of 0.1 mm. The robot is powered by a battery exceeding 1 kWh that enables over 8 hours of continuous operation, and it moves omnidirectionally at speeds up to 2 m/s. A high-performance computing platform delivering 200 TOPS supports the D7's multi-layered intelligence system for real-time perception, autonomous navigation, and hierarchical task planning [1][2].
The D7 was the first of three products released by Pudu X-Lab, the company's dedicated humanoid R&D division, in 2024. It was followed by the PUDU DH11 dexterous hand and the fully bipedal Pudu D9 humanoid robot in December 2024. Pudu positions the D7 as a practical, commercially viable platform for structured indoor environments such as hotels, hospitals, and logistics facilities, where long runtime and manipulation precision matter more than bipedal locomotion [1][3].
Pudu Robotics (formally Shenzhen Pudu Technology Co., Ltd.) was founded in 2016 by Felix Zhang, a serial entrepreneur who studied mechanical engineering as an undergraduate before earning a master's degree in computer science from the Hong Kong University of Science and Technology (HKUST). At the age of 20, Zhang placed first for China at ABU Robocon, a prestigious Asian-Oceanian college robot competition. He founded Pudu with the mission of "using robots to improve the efficiency of human production and living," initially targeting the restaurant industry [4][5].
The company released its first delivery robot, PuduBot, and rapidly expanded its product lineup. Key products include the BellaBot (a cat-themed delivery robot that became the company's flagship), HolaBot (a delivery robot with call-button summoning), KettyBot (a welcome and advertising robot designed for narrow spaces), FlashBot (a multi-floor delivery robot for hotels and office buildings), and a line of commercial cleaning robots including the CC1 scrubber and BG1 series of AI-native scrubber-dryers [5][6].
Pudu Robotics has raised approximately $192 million across at least eight funding rounds, with investors including Meituan, Sequoia Capital China, and Sierra Ventures. The Series C1 and C2 rounds alone raised nearly $155 million combined [7][8]. As of 2025, the company reports having shipped over 120,000 robots to more than 80 countries and regions. Notable customers include Marriott, Hilton, McDonald's, KFC, Walmart, and PizzaHut. Japan's Skylark restaurant group placed a single order for 3,000 BellaBots, setting an industry record for commercial service robots [5][9]. Pudu operates a 40,000-square-meter "super factory" in Jiangsu Province, China, and in March 2025 established a new US headquarters in Santa Clara, California, alongside an East Coast fulfillment center in Hamilton, New Jersey [10][11].
Pudu X-Lab is the company's dedicated research and development division focused on humanoid robotics and embodied intelligence. The lab was established to leverage Pudu's extensive experience in commercial robotics, particularly in navigation, fleet management, and mass manufacturing, toward the development of next-generation humanoid platforms [3].
In May 2024, Pudu Robotics formally introduced the "semi-humanoid robot" concept as part of its long-term strategic vision. CEO Felix Zhang described a three-tier robotic ecosystem consisting of specialized robots for specific tasks (the existing delivery and cleaning product lines), semi-humanoid robots for adaptable applications (the D7), and fully humanoid robots for complex interactions requiring bipedal locomotion and dexterous manipulation (the Pudu D9). Zhang characterized this as a "comprehensive layout" addressing the commercialization challenges of embodied intelligence across different price points and capability tiers [12][13].
In 2024, the X-Lab released three products in rapid succession:
In March 2025, Pudu further expanded this ecosystem with the FlashBot Arm, a semi-humanoid service robot that combines dual 7-DOF arms and DH11 hands with the existing FlashBot Max delivery platform, targeting hotels, offices, and restaurants [15].
The PUDU D7 was designed around the principle that a wheeled base with a humanoid upper body can provide a better balance of flexibility and affordability than either fully specialized robots or fully bipedal humanoids. Pudu's engineering team recognized that many commercial environments, including hotels, hospitals, office buildings, and warehouses, consist of flat indoor surfaces where bipedal locomotion offers little advantage over wheels. By keeping the wheeled chassis, the D7 avoids the engineering complexity, energy consumption, and stability challenges associated with bipedal walking, while gaining manipulation and interaction capabilities through its human-like upper body [13][16].
Pudu's blog on semi-humanoid robot design notes that wheeled semi-humanoids achieve "higher speeds and maintaining better balance due to their wheels' constant contact" with the ground compared to bipedal alternatives. The wheeled platform also provides inherent resilience: the robot can continue operating even if one wheel malfunctions. Energy consumption is significantly lower than bipedal systems that require complex gait control algorithms, which directly translates into the D7's 8+ hour runtime, a figure that would be difficult to achieve with a bipedal platform of similar size [16].
The D7 is designed to operate in "brownfield" environments, meaning existing human-designed spaces rather than purpose-built automation facilities. This orientation reflects Pudu's years of experience deploying delivery and cleaning robots in restaurants, hotels, and commercial buildings where robots must navigate alongside human workers and customers [16].
The D7's bionic arms represent a key differentiator from Pudu's existing wheeled robots, which are limited to carrying items on trays or within enclosed compartments. Each arm features 5 rotational joints and 2 linear joints, providing 7 degrees of freedom per arm. This joint configuration delivers precise and powerful actuation, supporting a 10 kg payload per arm with endpoint repeatability of 0.1 mm. The arms extend to 65 cm, enabling the D7 to reach objects at various heights and distances, including elevator buttons, shelf items, and sorting bins [1][2].
The base D7 operates with 30 total degrees of freedom. When paired with a dexterous hand attachment (such as the PUDU DH11), the total DOF expands to 50, significantly enhancing the robot's ability to perform fine manipulation tasks such as grasping irregularly shaped objects, turning handles, and pressing buttons [1][14].
The D7's omnidirectional wheeled chassis provides 360-degree movement capability, allowing the robot to move in any direction without first reorienting its body (holonomic movement). This is particularly valuable in confined spaces such as elevator cabins, narrow corridors, and crowded service areas. The chassis can climb obstacles up to 50 mm in height and maintains stability on slopes up to 10 degrees, accommodating ramps and slight grade changes found in commercial buildings [1][2].
The maximum travel speed of 2 m/s (7.2 km/h or 4.5 mph) matches a brisk human walking pace, enabling the D7 to keep up with the flow of activity in service environments without outpacing the people around it [1].

The D7 is equipped with a multimodal sensor suite that supports high-accuracy positioning, obstacle detection, and environmental mapping. The sensor array includes RGB cameras, a depth camera, LiDAR, an inertial measurement unit (IMU), force/torque sensors, a gyroscope, an accelerometer, and joint encoders. These sensors feed into the robot's AI system for real-time perception and autonomous navigation [2][17].
The sensor fusion approach builds on Pudu's extensive experience with SLAM (Simultaneous Localization and Mapping) and path-planning algorithms developed through years of deploying delivery and cleaning robots in complex indoor environments. The D7 uses both visual SLAM (VSLAM) and laser SLAM technologies to generate accurate 3D maps, navigate autonomously, and avoid obstacles in real time [16][17].
The D7 features a high-performance onboard computing platform delivering 200 TOPS (tera operations per second) of AI computing power. This enables complex machine learning inference, real-time computer vision processing, 3D environmental mapping, and autonomous decision-making directly on the robot without relying on cloud computing for time-sensitive operations [1][2].
The D7 employs a multi-layered intelligence system that merges data-driven embodied intelligence with advanced AI model strategies. The system uses a hierarchical control architecture consisting of two levels [1][2]:
This layered approach enables the D7 to understand and respond to complex service scenarios while continuously learning and refining its operations over time [1].
The D7's software stack is supported by three key components: Pudu OS, AI Studio, and simulation environments. Pudu OS provides the core operating system for robot control and fleet management, building on the same software infrastructure that manages Pudu's fleet of over 120,000 deployed service robots worldwide. AI Studio serves as the development platform for training and deploying AI models. The simulation environments enable continuous learning and optimization of robot behaviors before deployment in real-world settings [2][17].
Pudu has noted that advanced language models and vision systems enhance the D7's capabilities. The company's blog references the integration of large language models (LLMs) in Pudu Robotics' products to "enable robots to better understand and interact with their environments," suggesting that the D7's AI system incorporates natural language understanding for command interpretation [16].
The D7 targets a range of commercial and industrial applications that require manipulation capabilities beyond simple delivery but do not demand bipedal locomotion [1][2]:
Pudu envisions the D7 operating within collaborative workflows alongside other specialized Pudu robots. For example, in a hospital setting, specialized cleaning robots could handle floor maintenance while the D7 manages supply transport and the human staff focuses on patient care [16].
The Pudu D7 and Pudu D9 represent two complementary approaches to humanoid robotics within Pudu's product strategy. The D7, unveiled in September 2024, is a semi-humanoid that combines a human-like upper body with a wheeled omnidirectional chassis. The D9, unveiled three months later in December 2024, is a full bipedal humanoid standing 170 cm tall and weighing 65 kg. The two platforms are designed for different use cases and operational environments [1][3].

The D7's wheeled mobility provides several practical advantages for indoor deployments. Its energy efficiency translates into over 8 hours of continuous operation, roughly double what can be expected from similarly sized bipedal platforms. The constant wheel-ground contact ensures inherently stable movement without the computational overhead of gait control. Its 0.1 mm endpoint precision makes it particularly well suited for tasks requiring fine positional accuracy [1][3].
The D9's bipedal design sacrifices the D7's energy efficiency and long runtime in exchange for the ability to navigate stairs, slopes, and uneven terrain. Its higher payload capacity (20+ kg combined versus the D7's 10 kg per arm) and greater number of degrees of freedom make it better suited for heavy-duty manipulation tasks in environments with multi-level access requirements. The D9 also comes standard with the PUDU DH11 dexterous hands, providing 11 DOF per hand with 1,018 tactile sensor pixels for advanced haptic feedback [3][14].
Pudu's strategy of offering both platforms reflects the company's view that no single form factor can optimally address all commercial robotics applications. The D7 targets structured indoor environments where long runtime and precision matter most, while the D9 targets environments where terrain adaptability and heavy payload handling are more critical [12].
The D7 enters a growing market for semi-humanoid and wheeled humanoid robots, a category that has gained traction as companies recognize that bipedal locomotion is not necessary for many commercial applications. The wheel-drive segment held the largest market share (65.6%) in the broader humanoid robot market as of 2024, reflecting the practical advantages of wheeled platforms in indoor service environments [18].
Several companies have developed or announced wheeled humanoid platforms that compete in the same market space as the D7:
| Feature | Pudu D7 | Keenon XMAN-R1 | SwitchBot Onero H1 | FlashBot Arm (Pudu) |
|---|---|---|---|---|
| Type | Semi-humanoid (wheeled) | Wheeled humanoid | Wheeled humanoid | Semi-humanoid (wheeled) |
| Height | 165 cm | ~170 cm | 130 cm | Not disclosed |

| Arm payload | 10 kg | ~20 kg (est.) | Not disclosed | Not disclosed |
| Runtime | 8+ hours | Not disclosed | Not disclosed | ~8 hours |
| Target market | Commercial/industrial | Commercial service | Consumer/home | Commercial service |
| Status (2025) | Pre-commercialization | Prototype | Pre-order ($1,500) | Commercially available |
Keenon Robotics, another major Chinese service robot manufacturer that has shipped over 100,000 robots globally, unveiled the XMAN-R1 wheeled humanoid in March 2025. Like Pudu, Keenon is leveraging its established service robot business and distribution network to enter the humanoid market [19]. The SwitchBot Onero H1, unveiled at CES 2026, takes a consumer-oriented approach with a much smaller form factor and lower price point ($1,500), targeting household tasks rather than commercial applications [20].
Pudu's own FlashBot Arm, released in March 2025, serves as a more commercially ready semi-humanoid that combines dual 7-DOF arms and DH11 dexterous hands with the proven FlashBot Max delivery platform. While less capable than the D7 in terms of total degrees of freedom and endpoint precision, the FlashBot Arm benefits from the FlashBot's existing commercial infrastructure and is already available for deployment [15].
The D7 also competes indirectly with fully bipedal humanoid robots from companies such as Unitree Robotics (the Unitree G1 starting at $16,000), Tesla (the Optimus), Figure AI (the Figure 02), and Agility Robotics (the Digit). While these bipedal platforms offer greater terrain versatility, the D7's advantages in runtime, stability, and endpoint precision may make it more practical for many indoor commercial deployments [3][21].
Pudu's competitive advantages across its humanoid product line include its established global distribution network spanning 80+ countries, existing customer relationships with major brands, manufacturing scale (120,000+ robots shipped), and service infrastructure with over 300 local distributors and service providers in the Americas alone. These assets could enable faster commercial deployment of the D7 compared to humanoid startups that must build distribution and support networks from scratch [5][10][11].
Pudu anticipated full commercialization of the D7 in 2025 [1]. The robot's design for "brownfield" environments, meaning existing human-designed spaces, positions it as a near-term practical solution rather than a research platform. Pudu's existing manufacturing infrastructure, including the 40,000-square-meter Jiangsu factory that has already produced over 80,000 robots, provides the production capacity needed for scaling D7 manufacturing [10].
The global humanoid robot market is projected to grow from approximately $1.5 billion in 2024 to $9.4 billion by 2030, with a compound annual growth rate (CAGR) of 36.2%. Industry analysts note that the most promising short-term commercial applications for humanoid and semi-humanoid robots lie in semi-structured tasks such as item picking, palletizing, and material handling in warehouses and factories, aligning closely with the D7's demonstrated capabilities [16][18].
