A sanity chip is what makes sure robots don't harm humans.
In the three million years the mechanoid Hudzen-10 spent searching for his replacement Kryten aboard the Red Dwarf, Hudzen-10 wore out his sanity chip. The consequence of this was that when he finally came aboard Red Dwarf, Hudzen-10 had no issue with harming the other Dwarfers when they got in his way. ("The Last Day")
