Motor

Joint torque: 33.5NM. (MAX)

Maximum joint speed: 21rad/s.

Joints support quick removal and easy maintenance.

Industrial grade cross roller bearings for long life and axial shock resistance.

Read all sensor data.

Position, speed, and torque commands can be sent to each motor separately.

4 Foot-end Pressure Sensors

Accurate access to foot support information is more reliable, efficient, and convenient.

Rich External Interfaces

HDMI x 2, Ethernet port x 2 USB x 4

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

The fastest and most stable small and medium-sized quadruped robot in China. (World record: 3.7m/s, achieved by MIT on a treadmill).

The speed of 3.3m/s is close to adult jogging and can be used as a running partner.

Excellent Stability

Advanced dynamic balancing algorithm that allows A1 to meet impacts,
emergencies such as falls can quickly regain balance.

Patented Fuselage
Structure and Layout Design

High-strength and lightweight body structure, simple and convenient maintenance

24V external power input interface, 5V, 12V, 19V external output power supply,
easy to connect to external expansion devices

Standard high-performance on-board dual master control (perception master and motion master).

External interface: 4 USB, 2 HDMI, 2 Ethernet ports.

Standard RealSense depth camera, building + obstacle avoidance.

Sensitive
Foot-end Sensing

The integrated force sensor at each foot end is convenient for the robot to perceive the contact state of the foot end in real-time in any state of motion.

Hardware force sensors and motor current sense of foot end force are integrated into the program, for better sensitivity and reliability.

The foot end is waterproof and dustproof, and it is easy to replace.

Vision-based Autonomous Following

Follow targets (people, specific moving objects) in the visual range in real-time.

High real-time follow-up, video traffic refresh speeds up to 25-30 frames/s.

Support online learning of following target characteristics with good robustness performance.

The real-time confidence level of the tracking target is displayed by adjusting the color of the tracking box (green→ red, 100%→0%).

Vision-based Autonomous Obstacle Avoidance

Dodge obstacles within 0 .8m of the robot's viewing angle.

The distribution of obstacles within the robot's viewing angle can be monitored in real time and the position of the fuselage can be adjusted.

Real-time display of the adjustment angle of the robot fuselage, the maximum distance and area within the viewing angle, and the range of the upcoming walking trajectory.

Ultimate Hardware and Software Reliability

Deeply engaged in the field of four-legged robots for more than 6 years.

At the 2020CES, single set A1 successfully demonstrated more than 80 backflips in a row.

Closed-loop flip algorithm is adopted to ensure motion stability.
