The War of The Worlds - a tripod robot
New Scientist has published an article on a tripedal robot - it "walks" in a rather unconventional way by swinging its entire body upside-down with each stride.
Have a look - the video is fun to behold.
This may serve as an inspiration for another LEGO walker...
The video clip (in full size) is definitely worth watching.
I'll bet that some NXT sharpie could build a smaller version, if they could find someplace to put the brick. :)
I see wires are the biggest obstacle when you do multiple degrees of freedom and when you transform a perfect simulation that conforms to laws of physics to real world.
What do you think?
