Well, not really like that. You put different constraints between two objects, such as:
Rope
Pulley
Hydraulic
Motor
Winch
Elastic
Ball socket
Axis
Weld

Then, there's other things, such as thrusters, turrets, balloons, and hover-balls to make the contraptions do whatever you want it too. Don't be surprised if your stuff spazzes out at first - it takes a little work.
I also build a rocket powered flyswatter.
