available.

A1
--

`A1 <https://quadruped.de/unitree-a1-en/>`__ has an optimal design due
to which it can not reduce the cost but make the service life and motion
performance better. The robot can be controlled with Android and IOS
apps as well as ROS.

It has 2 modes to work:

1. Normal mode
2. Sports mode

In sports mode the robot can get the maximum performance and can run
upto 3.3 m/s speed, having 33.5 NM torque. With that much power the
robot can do back flips quite easily.

Moreover the robot is equipped with a depth camera with transmission
quality of 720P with 30 frames per second. The robot can be equipped
with a lidar and NVIDIA TX2 boards for operations like slam, autonomus
navigation and obstacle avoidance.
