A few years ago, news emerged about China’s rapid progress in developing AI-powered robotic dogs.
Chinese robotics leaders have quickly moved their early prototypes to mass production. The robotic dogs have evolved to get around independently, conduct surveillance, and collaborate in swarms. They can even walk on two legs and transport humans.
Today, the sheer volume of Chinese robot dogs with advanced capabilities hitting the market is alarming the West. As China scales production of its robotic dogs at increasingly lower costs, the West struggles to compete.
China’s military is actively assembling an autonomous robot army, including quadrupedal bots for reconnaissance, strike missions, and logistics support. The People’s Liberation Army’s strategy involves embedding civilian technological advancements into military applications.
It’s increasingly likely that you, or someone you know, owns one or several Chinese quadrupeds. Here’s a look at the Chinese robotic dogs making the biggest impact today in everything from industrial inspections and logistics to military operations and personal companionship.
Unitree Robotics
Unitree Robotics introduced quadrupedal robots to the consumer market in 2023 with its Go2. The starting price is around $1,600, providing an affordable alternative to Boston Dynamics’ $75K quadruped Spot. The price point has made the Go2 popular with researchers, hobbyists, and even influencers.
The Go2 runs at a pace of 3.5 m/ps (8 mph). It runs silently and has safety features for home and professional environments. It has a small payload capacity of 5 kg and operates for up to 2 hours on a single charge.
A wheeled version of the Go2 reaches speeds up to 2.5 m/s (5.6 mph) per second, or 5 point and performs acrobatic maneuvers.
The Go2’s growing ubiquity is raising concerns, as University of Pennsylvania researchers recently demonstrated its AI could easily be jailbroken.
Unitree’s higher-end quadruped, the B2, features an industrial-grade build for heavy-duty tasks. Its speed maxes out at 6 m/s (13.5 mph) and can carry loads exceeding 40 kg. The B2, which runs for more than 5 hours on a single charge, has gone viral with its terrain adaptability
Its pricing, starting at a hundred thousand dollars, is aimed at industries needing robust robots for inspections, logistics, and other demanding applications.
DEEP Robotics
Hangzhou-based Deep Robotics is also gaining a reputation for its full lineup of AI-powered quadrupedal robots. Founded in 2017, the company’s quadrupeds start at under three thousand dollars and reach speeds up to 5 m/s (11+ mph).
The lineup includes:
- The Lite3, an entry robot for research, education, and testing applications
- The X20, which is designed for patrol inspections and excels in wet and dusty conditions
- The X30, which navigates steep industrial surfaces in temperatures as low as -20 Celsius
- The Lynx, a high-speed robot outfitted with all-terrain wheels
RoboWolf
The China South Industries Corporation is a state-owned supplier of advanced military systems, including quadrupeds commonly referred to as RoboWolves.
The Beijing-based enterprise’s quadrupeds excel at navigating complex terrains, including city streets, factories, mines, caves, and stairs. Weighing about 70 kg, a RoboWolf operates for up to 3 hours with a single charge with a combat radius of 7 kilometers.
The robots support payloads for reconnaissance, communication, weapons, and supplies, adapting to mission needs. The robot connects with as many as 30 other robots or devices to work together as a team.
Robo wolves can share info and coordinate their actions without constant human control. They’re also capable of air-ground collaborative operations when integrated with drones.
The robo wolves were first showcased at Airshow China 2024. It’s unknown how many of the robotic dogs have been produced.
Mechanical Yak
China unveiled what it calls the world’s largest quadruped bionic robot, often referred to as the mechanical yak, in January 2022. Its exact weight and size are unknown, but it’s described as being the heaviest robot of its kind.
It reportedly has a payload capacity of 160 kg (352 lbs). It can run at speeds up to 10 km/h (6.2 mph). At that pace, the quadruped would finish a 5K race within 30 minutes, which is about the same as an average recreational human runner.
With its terrain adaptability, the mechanical yak is intended for transporting supplies like munitions and food in challenging environments and gathering battlefield intelligence and monitoring targets. Equipped with sensors to perceive its surroundings, the robot can perform tasks autonomously with minimal human intervention.
LimX Dynamics
The W1 quadruped by LimX Dynamics is notable for its ability to transform into a bipedal robot.
With its advanced actuators and control system, the wheeled robot stands upright, rotates, and navigates obstacles seamlessly. Its cameras see terrain in real-time to avoid obstacles.
The quadruped travels at speeds up to 10 m/s (over 22 mph). The 40 kg robot can adjust its height during high-speed motions. Its quick-swappable batteries last about 4 hours.
With its 15 kg payload capacity, the W1 is intended for inspections in dangerous settings like factories, mines, and power plants and assisting during emergencies and rescue missions. LimX says the robot is also geared toward research and development, logistics, and unmanned last-mile delivery.
Pudu Robotics
Pudu Robotics, a Shenzen-based firm that’s deployed more than 80 thousand units globally, introduced its first quadrupedal delivery robot in 2022.
The PUDU D1 features proprietary, high-performance joints that can retain absolute position data, even amid power interruptions. Its 16-core CPU powers AI computing capabilities up to 30 Tops. With the processing power, the robot can tackle complex navigation tasks, avoid obstacles in real-time, and manage advanced AI-driven interactions.
Its flexible force control maintains balance across terrains. The robot’s auto-leveling delivery compartment remains horizontal, ensuring safe transport of items.
Pudu Robotics says its quadruped is suited for places like restaurants, industrial parks, and residential communities.
Xiaomi
Consumer electronics giant Xiaomi introduced the first edition of its $3,000 Cyberdog in 2021. The company unleashed Cyberdog 2 in 2023.
Weighing 14 kg, the quadruped serves as an open-source platform for developers and robotics enthusiasts. With its high-performance servo motors, Cyberdog achieves a top speed of 3.2 m/s. Its 11 high-precision sensors including tactile, cameras, ultrasonic, and GPS modules allow the robot to perceive and interact with its dynamic surroundings.
It has enhanced depth sensing and object recognition capabilities thanks to its AI interactive cameras, binocular ultra-wide-angle fisheye cameras, and Intel Real Sense D 4 50 depth module. It’s powered by NVIDIA’s Jetson Xavier NX AI platform.
Users can control the robotic dog via voice commands, a smartphone app, or remote control. It supports voice control with six built-in microphones for better sound perception.
The robot’s three USB Type C ports and single HDMI port allow users to customize and expand its hardware, adding accessories like LiDAR sensors, panoramic cameras, and search lights.
Weilan Robotics
Alpha Dog, by Shenzhen-based Weilan Robotics, is another relatively affordable quadruped. It’s also one of the fastest, reaching speeds up to 15 km/h (9 mph).
Starting around $2,400, the Alpha Dog’s diverse use cases include companionship, industrial inspections, and assisting the visually impaired. The Alpha Dog is available in several configurations, including the C100 for beginners and hobbyists, the C200 for professional and enterprise-level tasks, and the E300 and E400 for industrial-grade performance.
Weilan also offers a Baby Alpha robot starting at less than a thousand dollars for companionship, education, and development applications.
