There have been quite a few posts on nature inspired computing. Here is another, this is a really cool video on the same. Have a look at the gait of the yellow salamander mimic bot and also the caterpillar bot at the end of the video!
The introduction to this video reads as:
Robotics researchers are increasingly turning to nature for inspiration. Watch a robotic salamander, a water strider robot, mechanical cockroaches and some cool self-configuring robots.

My congratulations and best wishes to the researchers who are trying to develop such bots and also to New Scientist for such a good video!
