Whole Machine Clean
 Clean
When the B1 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 B1 robot (including battery pack) has IP67 waterproof. (IP68 is optional.) Do not remove the
battery pack when cleaning!
 Storage
The B1 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.
Inspection and Maintenance
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.
