Hi
According to what I have heard, several human errors were the cause of this fatality:
The accident happened at a robot cell that was being set up. For some reason the safety circuit was not set up, so an override of the safety was used (probably some sort of key?).
The victim, who was a robot programmer, went into the cell and worked on the robot while it was in automatic mode.
A second man, the plc programmer, was outside the cell. Because the cell was still being set up, all of the plexiglass was will covered by plastic foil, so he had no direct line of sight into the cell. He had not seen anyone go into the cell, so he assumed that noone was inside. He wanted to test something, so he pressed the start-button (without checking that noone was actually inside). The robot started moving while the robot programmer was standing next to it, and the robot programmer was crushed to death by the robot (probably against a wall or something).
The errors where:
1) Safety should not have been overridden the way it was.
2) The robot programmer should not have been standing inside the cell with the robot in automatic mode.
3) The PLC programmer should have looked inside the cell, before he pressed "start".
So both the robot programmer and the plc programmer were at fault, according to my source.
I guess that this line of work becomes extra dangerous when several people are working on the same system at the same time.

Hello again
Regarding the type of robot: Since this was at VW, i would assume that the robot was a 6-axis KUKA or ABB robot.

Thanks for the Info.
And the anyone in the cell should have the teach pendant or dead man switch with them, regardless if the external perimeter or e-stop safety circuit was finished.
