so it was SUPPOSED to kill a man? "yup...all good here. working as programmed"
I assume your comment is hyperbole. The lack of a technical defect means that the machine did not malfunction in order to undertake the movement that ended up with the man pinned against the safety cage.
It does not reflect intent at all.
The next question is whether the robot was under autonomous control, or if there was an outside control applied (such as a human manipulating the robot). Right after that is whether the technician bypassed any of the safety protocols that are designed to prevent accidents like these.
