Robotic Dogs and... Lobster?

The field of robotics has long taken cues from the natural world in the goal to create a versatile, able machine, and has found it exceedingly difficult to match the functionality which we take for granted in living organisms.

Two of the more recent ventures into the field of biomimetics - the mimicry of biologicals - include BigDog, a dane-sized canine-copy slated to be born in 18 months. If the design pans out, the motorcycle-powered creation should be able to run at over 15 MPH, and jump over three feet high.

Even further removed from the consumer-friendly world of the likes of Asimo is RoboLobster, a clawed creature complete with hard shell, eight legs, and antennae, purpose built to hunt for mines in shallow water.

Both are designed with the military in mind, and recieve funding from DARPA and the Navy. If you're seeking more "human" robots, a list of the most ambitious projects is here.
