Unitree Aliengo – robust, high-performance quadruped robot
Unitree Aliengo, which was designed as a research platform, is a high-performance quadruped robot that can traverse uneven terrain, climb gradients of up to 21° and remain stable even if kicked, all at a maximum speed of 1.5 m/s for up to 4 hours on a single charge. An integrated depth perception vision system enables real-time 3D map creation and navigation planning, along with human posture recognition tracking and face recognition.
An impressive payload capacity of 10 kg, combined with a rich external interface and ROS support, make sensor integration with this robot dog simple and straightforward. While incredible agility and a range of special movements, including backflips, creeping, and lateral locomotion, allow Aliengo to navigate complex environments.

Features
High performance
- The patented design is based on rigorously tested self-developed technology so that Aliengo is calibrated to derive maximum performance for the longest possible time, while it’s integrated body is made of polymer plastic, carbon fibre and aviation-grade aluminium.
Long life
- Unitree Robotics has developed a lithium battery pack with an incredible 4.5 hour operating time, allied with an intelligent built-in air cooling system that automatically senses the temperature and cools accordingly.
Incredible stability
- Advanced dynamic balancing algorithm enabling swift regain of balance following impact or falls.
- Force control technology grants compound control of the robot dog’s joints, realising full control of triple-axis posture and position for multi-terrain adaptability. Aliengo can run with equally strong stability on rugged gravel roads or grass.

Depth vision – real-time 3D map creation and navigation planning
3D environment construction – while in motion Aliengo uses the cameras to obtain colour and depth information of the environment, then reconstructs the 3D spatial information of objects with the help of a specific vision algorithm.
Probability map – octomaps / probability maps are created bu the cameras as the robot moves, detecting surroundings and providing obstacle data.
Dynamic obstacle perception – when the robot encounters a dynamic obstacle it refreshes that map data within a particular range, discarding the ‘moving artefact’ left by the dynamic obstacle on the map.
Global positioning – global and local real-time positioning functions are available during the process of map creation. The map will follow the camera’s perspective in real-time, supporting real-time zoom, movement and rotation.
Loop detection – Aliengo maintains high loop-back accuracy in a wide range of fields, high positioning accuracy within a certain range, maintaining stability with a certain oscillation amplitude, with drift or loss.
Human posture recognition tracking and face recognition
Body posture recognition – Aliengo’s deep learning module enables the colour camera to identify specific human postures and conduct human-machine interaction, the robot can then make movements that correspond to different body postures.
Human skeleton perception – the robot can analyse and calculate the two-dimensional skeleton information of the human body according to colour information from perspective, and analyse and calculate the three-dimensional skeleton information and motion of a specific character using depths of field.
Target person tracking – when multiple pedestrians are present, Aliengo can be instructed to lock on to an individual by a particular posture (eg raising the left hand), the robot will then follow the movement of the target,
