I tend to use beams / leftarms with non friction pins instead - they are more effective and dont come apart as easilly.
On the other I have used it for cosmetic reasons - e.g. to support a pivotable robot head from either side to make it tilt left and right.
I've seen this before in the the pen assembly of The NXT Step Idea book's Marty robot. In addition, I've seen it used in the "Orange Book". There was a small humanoid robot that could open its mouth or raise its eyebrows - both mechanisms augmented by this type of beam.
I've also used them to secure NXT cables. You can run a piece on two of the black friction ball pins. Then connect the piece across them. Run the NXT cable under the piece. It keeps it from flapping around. You can run a couple under one piece this way.
Could someone please to a post asking what 'Technic Axle Joiner Double Flexible' (45590)(name from peeron.com) is used for?
