Hi ASalazarMX - no it couldn't. We have software constraints around speed and position. Additionally, there's hardware checks that shut down the arm if it moves too fast and/or encounters too much pressure.
Edit: Since you mentioned it's an UR3, its payload is probably the same as the UR3e (3 Kg), so no neck breaking strength. Maybe strangulation if the user cooperates.
Clearly another untapped business opportunity.
