A1

The A1 high-motion performance quadruped robot platform consists of a quadruped robot, a remote control and supporting remote control software. The whole machine has 12 degrees of freedom (composed of 12 high-performance servo motors). The force control technology is used to perform compound control of the force and position of each joint, so as to realize the force control of the whole machine and obtain excellent sports performance. Use streamlined mechanical structure to reduce manufacturing difficulty and improve machine reliability. The robot has reached the leading level at home and abroad in terms of structure, motion performance and cost.

Features

Better performance: A1 has carried out function expansion and performance optimization on the basis of conventional motion; the overall optimization design has greatly reduced the cost of the quadruped robot, while also greatly improving the motion performance and service life. In sports mode, the maximum joint speed of 21rad/s enables A1 to speed up to 3.3m/s instantly, with super balance ability; 33.5NM torque makes A1 easy to realize back somersault; joint parts can be quickly disassembled, easy to maintain.

Multifunctional application: The addition of the multi-lens depth camera allows the quadruped robot platform to have real-time image transmission (image transmission quality 720P/30fps) and intelligent applications such as person following; and support secondary development.

Scalable design: Optional lidar can complete dynamic obstacle avoidance, navigation planning, autonomous positioning, map construction and other expanded functions; optional NVIDIA TX2 can perform visual SLAM, gesture recognition, and artificial intelligence research (such as machine learning).

Easy to use: A1 supports APP control of Android and IOS.
