Unitree Laikago
By: Unitree Robotics
Launched: 2017
Unitree Laikago is the first commercial quadruped from Unitree Robotics, the Hangzhou company that went on to make the Go and B series. Named after Laika, the first dog to orbit Earth, it showed that a nimble, all-electric robot dog could be built from low-cost brushless motors and in-house controllers. It walks forward, backward and sideways, climbs grassy slopes, crosses loose rocks and keeps its balance when pushed or kicked, adjusting its body angle as the ground shifts. It was sold mainly to universities as a research platform, and it led directly to the AlienGo and later Unitree robot dogs.
Unitree As2
By: Unitree Robotics
Launched: 2026
The Unitree As2 is a compact industrial quadruped robot dog designed for demanding environments where larger machines cannot operate. Weighing just 18 kg with battery, it delivers exceptional performance with maximum joint torque of 90 N·m, enabling it to carry up to 65 kg standing or 15 kg continuous payload while navigating uneven terrain. It achieves speeds over 5 m/s (11+ mph), climbs 40-degree slopes, and offers over 4 hours of runtime unloaded or 2.5+ hours with payload, covering more than 13 km. IP54-rated Pro and Edu models handle rain, dust, and temperatures from -20°C to 50°C. Equipped with LiDAR, HD camera, front lighting, 8-core CPU, and ISS 3.0 for centimeter-level person following, it supports autonomous navigation, remote control, and secondary development with NVIDIA Jetson Orin NX. Targeted at industrial inspection, security patrols, logistics, emergency response, and AI research, the As2 combines agility, endurance, and open architecture for versatile applications in confined spaces.
Unitree A1
By: Unitree Robotics
Launched: 2020
The Unitree A1 is a highly integrated quadruped robot dog designed for advanced mobility, stability, and versatility in dynamic environments. Developed by Unitree Robotics, it excels in athletic performance with capabilities like high-speed running up to 3.3 m/s (11.88 km/h), backflips, rolling, dancing, and stair climbing up to 12 cm steps. Powered by 12 high-performance brushless DC motors with 33.5 Nm torque and 21 rad/s speed, it features 12 degrees of freedom for agile gaits including trot, walk, and gallop. Equipped with an Intel RealSense D435i depth camera for real-time HD video transmission, human following, object tracking, and obstacle avoidance within 0.8 m, it also includes four foot-end force sensors for terrain adaptation and balance recovery. With a 5 kg payload capacity, rich interfaces (HDMI, Ethernet, USB), and support for secondary development via APIs and ROS, the A1 targets research, education, inspection, entertainment, and potential industrial applications. Optional modules like LiDAR enable SLAM, navigation, and autonomous operation, making it a robust platform for developers and a record-holding fast quadruped.
