3.2. Vacuum Gripper
The vacuum gripper can dynamically suck the smooth plane object with
payload ≤5kg. The vacuum gripper is equipped with 5 suction cups,
which can be partially selected for use according to the size of the object
surface, and the unused suction cup needs to be sealed.
Note:
If the surface of the object is not smooth, there will be air leakage from
the suction cup which makes the object fail to be sucked up firmly.
Indicator status: When the vacuum gripper is powered on, the power
supply indicator near the vacuum gripper is constantly red. When the
vacuum gripper is on, the IO status indicator is constantly green.
