A simple solution I saw at GSR was 1519's. It is a simple triangle driven by a window motor that comes down and they just drive into the bridge and it comes down. Can easily be down with a limited weight budget! You can see it on the side of there robot here!
This design interests me, I wish I could get a better pic of that manipulator. I'l go hunting...

@Akash, You mentioned using a van door motor. Does that have enough torque to push the bridge down on its own, or is it better off being used for a wedge?
