Repairing After Collisions

Overview

Components may be damaged as a result of a collision.

WARNING
	FALLING OR EJECTED PARTS Thoroughly inspect all components of the robot and all components attached to the robot, including the motor and the gearbox, for damage after a collision. Do not use the robot if any of the components are damaged or suspected to be damaged. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Verifying the Robot After a Collision

WARNING
	COLLISION OF COMPONENTS Replace upper and/or lower arms if dents or cracks are observed or otherwise detected. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Step	Action
1	Verify the components for completeness. If any components are missing, locate the same and remove them from the surrounding machinery.
2	Replace damaged or missing components.
3	Verify the upper and lower arms for visible dents or cracks. Dents reduce the strength of the arms and may cause component breakdown.
4	Verify the calibration by moving the upper arms on the calibration bolts. NOTE: If the tolerance requirements for calibration are not met, replace the upper arms.
5	Verify the lower arms for straightness.
6	Release the brakes and manually move the robot to verify the ease of operation.
7	Close the brakes and verify that there is a small backlash in the gearboxes and no cracking noises.
8	Only for robots with a rotational axis (VRKP•••R): Rotate the telescopic axis in order to verify that the bearing in the parallel plate runs evenly and smoothly. NOTE: If the bearing cannot be rotated evenly and/or produces noises during the rotation of the axis, proceed as follows: Wash out the bearing in order to remove any foreign objects. Verify the bearing again. NOTE: If the ceramic rolling elements of the hybrid bearing are damaged, replace the parallel plate.
