What's AXEL Robot A1?

Axel is the quadruped robot that climbs stairs and traverses rough terrain with unprecedented ease, yet is small enough to use indoors. Built to be a rugged and customizable platform, Axel has a proven track record of supporting remote operation and autonomous sensing across a variety of industries, and is remarkably intuitive, enabling you to focus on the job you do best. Whether you are a Jobsite manager, sensor developer, performer, or anything in between, Axel is the adaptable platform you need to inspect, sense, perform, and more:

  • Inspect dangerous, inaccessible, and remote environments

  • Automate data collection on your site

  • Carry payloads on unstructured or unknown terrain.

Control Spot with its out-of-box controller or through the developer-friendly API. Spot’s tablet controller is designed to get you up and running quickly, with easy access to many of the robot’s capabilities, including body posing, walking gaits, obstacle avoidance, local navigation, and calibration. The tablet controller also enables the creation of basic autonomous missions through Autowalk, a feature where the user can create predefined routes for Spot to follow.

In some cases, such as basic remote inspection tasks, the tablet controller will be all you need to use Axel to add value to your business. To access additional capabilities and add features, develop on Axel’s Software Development Kit (SDK) to create your own applications for teleoperation, integrate payloads, and design full autonomy systems. Read more about what’s available in Axel’s SDK in our developer documentation.

The Axel system has been audited by third-party security experts. Messages between the robot and clients, as well as all data logged by the robot, are encrypted.

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.
Function / Specification A1 Motor Comparable Competitors
Maximun torque 33.5 N·m about 18 N·m
Weight 605g 480 ~ 550g
Joint Angular Acceleration Feedback Equipped No
Torque / Weight Ratio 55.37 N·m/kg 37.5 ~ 32.73 N·m/kg
Encoder Resolution 15bit 14bit
Output Bearing Reliability Large size reliable industrial cross roller bearings. Conventional thin wall bearings, which are fragile after falling or under axial impacts.

Patented Body Structure and Layout

  • High strength and light body structure. Easy to maintain. 24V external power input. 5V, 12V, 19V power supply. Convenient for additional external equipment.
  • Equipped with high-performance dual master control (sensing master control and motion master control).
  • External interface: 4USB, 2HDMI, 2*Ethernet
  • Master control can be upgraded to TX2.
  • Standard equipment include RealSense depth cameras.
  • Capable of map building and obstacle avoidance.

Patented Sensitive foot contact


  • Integrated force sensor at each foot end. Convenient for robot to obtain realtime contact states of feet under any situations. 
  • More accurate and sensitive than those systems that estimate feet contacts using motor currents. 
  • Integrate foot contact sensor with estimated motor current foot sensor, providing more  sensitivity and reliability
  • Foot end is waterproof and dust-proof, and easy to replace after wear and tear.

Vision-based Autonomous Object Tracking

  • Realtime tracking of objects within visual range.
  • Support online machine learning of the target features.
  • Displaying the confidence of tracking using color box (green → red, 100% → 0%) 


Vision-based Autonomous Obstacle Avoidance

  • Avoid obstacles within 0.8m of the robot's visual range
  • Capable of detecting the obstacle shapes to adjust the body position
  • Realtime display of the adjustment of robot body, maximum distance and area within the visual angle, and the range of walking track.

Choose To Assemble High Precision Lidar

  • Support map building, autonomous positioning, navigation planning and dynamic obstacle avoidance
