Unitree - Aliengo Basic Quadruped Robot

Aliengo is a quadruped robot capable of reconnaissance and inspection tasks, especially on rough terrain as it has a great balance capacity. Thanks to this, he can perform complex maneuvers such as somersaults.

Its main features are:

Supper-body long battery life. The maximum operating time can reach 4,5 hours.

Compound control of joints by force control technology. It can realice full control of 3-axis posture and position, so it has strong multi-terrain adaptability and can run stable on rugged gravel roads.

Excellent performance. 12 high-performance servo motors.

Special movements such as fast running, backflip or jumping.

The maximum walking speed exceeds 1,5 m/s.

The fuselaje has a Good ability to resist impact.

Open sources

Control interface support C/C++, ROS, etc.

Useful interface.

Depth perception vision.

Depth camera: the minimum sensing depth is about 0,11 m up to 1280 x 720 depth resolution.

People recognition and facial recognition.

Unitree will take the responsibility to install the lidar with protection bracket on robot.

Field Applications

HUMAN POSTURE RECOGNITION TRACKING AND FACE RECOGNITION

1. BODY POSTURE RECOGNITION

The colour camera can identify the specific posture of the person according to the deep learning model, and conduct human-machine interaction. The robot can make corresponding movements according to different body postures.

2. HUMAN SKELETON PERCEPTION

The robot can analyze and calculate the two-dimensional skeleton information of the human body according to the colour information from the perspective, and further analyze and calculate the three-dimensional skeleton information and motion information of a specific character using depths of field.

3. TARGET PERSON TRACKING

When there is more than one person in the scene, someone can tell the robot to lock he/she by a certain posture (for example, raising the left hand). There- after, the robot will follow the movement of the target, even during the movement.

4. FACE RECOGNITION AND APPEARANCE DETERMINATION(UNDER DEVELOPMENT)

From the perspective of the robot, artificial intelligence algorithm is used to automatically conduct face recognition and crowd classification, and it can identify gender, age and outfits.
