Checking for Oil Around Harmonic Drive
The Cobra s-series robots use oil in the harmonic drive components for lubrication. It is a
good idea to periodically inspect the robot for any signs of oil in areas around the
harmonic drive. Check these locations:
• the area around Joint 1
• the area around Joint 2
• inside the base of the robot
(Open the AIB chassis and inspect internally. Be sure to remove all power to the
robot before opening the AIB chassis.
Contact Adept if you find any signs of oil in these areas.
