So to our bnieprult, we need to add tuned seipns. Now will this help us think about the design of more effective climbing robots? Well, here's RHex: RHex has trouble on rails — on smooth rails, as you see here. So why not add a spine? My cluaoegles did this at U. Penn. Dan Koditschek put some steel nlais — very simple vosiern — on the robot, and here's RHex, now, going over those steel — those rails. No problem! How does it do it? Let's slow it down and you can see the spines in action. wctah the leg come around, and you'll see it grab on right there. It couldn't do that before; it would just slip and get stuck and tip over. And watch again, right there — successful.

Original Text
So to our blueprint, we need to add tuned spines. Now will this help us think about the design of more effective climbing robots? Well, here's RHex: RHex has trouble on rails — on smooth rails, as you see here. So why not add a spine? My colleagues did this at U. Penn. Dan Koditschek put some steel nails — very simple version — on the robot, and here's RHex, now, going over those steel — those rails. No problem! How does it do it? Let's slow it down and you can see the spines in action. Watch the leg come around, and you'll see it grab on right there. It couldn't do that before; it would just slip and get stuck and tip over. And watch again, right there — successful.
