The elegance of this solution is that the insect deals with the issues of climbing up and over and around obstacles while the human / external driver concentrates on the end objective. Since the "legwork" has historically been a hard part to program, the insect brain is doing the part for us that we have trouble with!
@harnhua: There're a lot of things we can learn via biomimicry!
I agree -- I'm constantly amazed by the way in which living organisms have evolved the most incredibly capabilities -- the folk screating robots and flying / swiming things are constantly learning from living creatures.
Lol, yeah those creatures have insisted to live with us so we've got to find them some work...sounds good to me because i'm imagining for instance in a rescue mission where other animals or people can not get to. Roaches can crawl through the rubble and find people or otherwise confirm their absence.
