You could buy a couple of air cylinders and use a 12 volt air compressor (
tyre inflator) to supply the air.

I am thinking of building a bed cover made out of wood and covered for
my bed of my truck. It would have a hinge so it would open and I could
store things like groceries, etc. It there a way to make it so the
hinged part could be opened automatically by a button or remote or
something? Can you help me find where the parts are?

Just thinking right now. Any helpful ideas are appreciated!
