I am of the opinion that if somebodys grabs you and while you are driving or moving to escape, their graber/hook breaks, that would be poor design/choice on there part, and their own fault.
However, a device designed to break off, ie choping pinching, an assailants grabbing device would not be in the spirt of FIRST.
So if you plan on grabbing another robot, build it sturdy enough to do the job properly.
