Best mechanisms

CD community:

I am working on a project and I need to compile a list of good/excellent examples of different mechanisms. I am looking specifically at individual mechanisms, not necessarily whole robots.

For example: in 2007 The Pink Team 233 had a great arm for handling inner tubes. It pivoted about the center of the chassis, telescoped and had a "C" shaped claw with rollers at the ends. Rollers were individually operated so the inner tube could be pivoted about the hold point.

If you can reach in your collective memory and provide a description (or even better a picture of video) I would appreciate it.

It does not matter how far back you have to go, a good mechanism is a good mechanism.

Thanks in advance.
