Robot Special Case Handling
Unitree uses a streamlined mechanical structure to reduce manufacturing difficulty and improve
machine reliability. Our robots have achieved good levels in terms of structure, dynamic performance,
kinematics and cost. The quadruped robots we develop are reliable and cost-effective. They are very
suitable for the exploration of scientific and field-level applications as a new four-legged mobile
platform, but when the external environment does not meet the requirements of robot operation or
improper use by users, The robot will have some abnormalities. In addition, in the developer mode, the
user will use the program developed by himself on the robot. This has great uncertainties and may
cause damage to the robot. Therefore, in the developer mode, please use the protective frame and
rope attached to the Unitree official.
Robot Black Box
The robot black box is mainly used to record the state information of the robot operation. After the
robot fails,, it can help the maintenance personnel to determine the cause of the machine fault more
quickly, and judge whether the cause of the machine fault belongs to the user's improper operation or
the robot hardware problem according to the black box data. After the robot is turned on, the robot
black box will record the machine's IMU, joint angle, joint speed, force sensor and other robot attitude
data, as well as internal historical data such as customer control commands and robot running time.
