If you are thinking pneumatics and mindstorms, you might check out an
electric pneumatic switch (made in Lego) at

Also, it is interesting to note that the piston of a fully charged and
extended cylinder will rotate with relative ease.
There is also an example of rocker-boogie suspension system for those who
have come from the robot mail list and might have missed the previous post
about
it on Lugnet. For those of you that have seen this post before I apologize.
