.&.&.&.&.. batteries may not harm a human or, .&.&.&.&.&
.&.&.&.&.& through inaction, allow a human being &&.&.&.&.&
.&.&.&.&.. to come to harm. .&.&.&.&.&
.&.&.&.&.& &&.&.&.&.&
.&.&.&.&.. a battery must obey the orders given it .&.&.&.&.&
.&.&.&.&.& by human beings except where such &&.&.&.&.&
.&.&.&.&.. orders conflict with the first law. .&.&.&.&.&
.&.&.&.&.& &&.&.&.&.&
.&.&.&.&.. a battery must protect its own .&.&.&.&.&
.&.&.&.&.& existence as long as such protection &&.&.&.&.&
.&.&.&.&.. does not conflict with the first or .&.&.&.&.&
.&.&.&.&.& second laws. &&.&.&.&.&
