I found this video of a robotic bee which I thought might be of interest (no pun intended).

Some things to note which might be of relevance to the reprap community.

1) The use of Kapton tape. It appears that they use it as a hinge (living hinge) when placed between solid layers.
2) A support structure which helps with bending and assembly and is then removed.
3) The use of a Sarrus linkage to guide linear movement.

Wow, that's a great video!
