1) Clean
When the B2 is used in harsh environments (rainy, dusty, wet), please clean the surface of the robot body
in time.
Before cleaning the robot body, please turn off the power, use a clean, soft cloth to wipe the body,
especially pay attention to whether the multi-view depth camera is wiped clean. It is strictly forbidden to use
metal brushes, sandpaper, etc. to clean to avoid scratching the surface of the parts. After cleaning, dry the body
with a soft cloth. After drying, use a fan or air gun to dry the accumulated water on the surface of the robot
and the joint gap to avoid leaving water marks.
⚫ Be careful! The whole B2 robot (including battery pack) has IP67 waterproof. Do not remove the battery
pack when cleaning!
2) Storage
The B2 should be stored in a dry and cool room and away from the sun and rain to avoid the corrosion of
parts and shorten the service life span. Take out the battery pack when storing for a long time.
Carrying out routine inspection before and after operation can greatly improve the reliable performance
of products, reduce potential safety hazards and extend the service life span.
