Quick overview

A1 is a quadruped robot capable of analyzing its environment, monitoring and overcoming obstacles, thanks to its intelligent sensorization.


Its wide mobility allows it to carry out many tasks: from parcel and material delivery tasks, through environmental inspection and security applications (recognition in dangerous areas) or within the framework of entertainment activities. On the other hand, it is the ideal robot for the R&D sector, where the applications are endless.

Its wide mobility allows it to carry out many tasks: from parcel and material delivery tasks, through environmental inspection and security applications (recognition in dangerous areas) or within the framework of entertainment activities. On the other hand, it is the ideal robot for the R&D sector, where the applications are endless.



Its main features are:

  • Higher running speed: Maximum continuous outdoor running speed at 3.3m/s (11.88km/h).
  • Multi eye intelligent camera: 1080P resolution.
  • Excellent motion stability.
  • High strength and light body structure.
  • Integrated force sensor at each foot end.
  • Vision-based autonomous object tracking.
  • Realtime tracking of objects within visual range.
  • Avoid obstacles within 0.8m of the robot's visual range.
  • High Precision Lidar to map building, autonomous positioning, navigation planning and dynamic obstacle avoidance.
  • Friendly User Interface.

  • Applications:

  • R&D
  • Load transport
  • Inspection
  • Security
  • Entertainment

  • The Explorer Version:

    Equipped Lidar and nVIDIA NX

    With Lidar, A1 will support 4 perception functions:

  • Dynamic obstacle avoidance,
  • Navigation planning,
  • Map building,
  • Selfpositioning.
  • Unitree will take the responsibility to install the lidar with protection bracket on robot.


    With nVIDIA NX, A1 will support development:

  • vslam,
  • gesture recognition,
  • machine learning,
  • etc.

  • Higher Running Speed


    Maximum continuous outdoor running speed at 3.3m/s (11.88km/h).

    The fastest and most stable small and medium sized quadruped robot on the market. (World Record: 3.7m/s on a treadmill by MIT)

    With the potential to be a great jogging companion.

    Excellent Motion Stability


    Advanced dynamic balancing algorithm enables A1 to quickly reach balance in different situations like impact or fall.

    Patented Power System


    The ultimate power system brings excellent performance, which is perfect of all kinds of robot competitions.

    Crucial for high-speed running.
