<sentencetext>A similar design might be used to explore unstable environments such as collapsed buildings or rocky landscapes.No, it won't.I made a hexapod with 3DOF per leg that could walk in any direction "from scratch" by myself, in high school, for fun.Adding some foot sensors is the obvious next step, and I've heard a lot about learning algorithms for walking robots being used over the years.Honestly, I'm only bitter because I made something cooler in college but never bothered to post it online, so no one saw it aside from my classmates.
But, it was a battery-powered 4 legged walking robot that ran a micro ITX windows XP pc inside its body, and was controlled through the internet with a remote PC by a wireless Xbox 360 controller.It was honestly totally badass.Oh, and it could support 20lbs static weight on its standard size hobby servo motors (but they were the $115 ones).But more than anything, my point was is wasn't that hard, and that robot wasn't going to be walking through rubble any time soon.It *could* have, but it wasn't going to.
Neither is this one.
People have been building basic hexapods for a long time.

	<htmltext>The configuration of the robot is not the accomplishment here, its the fact that robot can actually learn to walk on its own. As the article mentions; if a leg is damaged, it an re-learn how to walk without that leg. Most if not all hexapod robots would have a lot of trouble moving at all if one leg, or even two, were damaged. Based on what this thing seems to be capable of doing, that would only only probably mean a few minutes of down time before it started moving again. IT wouldnt have to be manually re-programmed to walk again without those legs. This is great for things like interplanetary robots where a single command takes weeks to transmit, when they dont even know if the robot is stuck until it has no way of getting itself out. I dont think the accomplishment is the robot itself but rather the programming that runs it.</htmltext>

An electrical engineer senior shouldn't have a problem building one of these without a kit, although it looks like he might have used <a href="http://www.hexapodrobot.com/products/robots/Hexapod\_MSR-H01.html" title="hexapodrobot.com">this kit</a> [hexapodrobot.com].
