How the robot deals with ice is incredible. Thanks for the link!

OMG!

When I started watching that I was thinking that if I was ever in a situation where this robot was chasing me uphill through a forest I would just run up to it and kick it over to slow it down. Then 30 seconds later they demonstrate how well you can expect that plan to turn out :)

Looks really Metal Gear-ish, doesn't it? A bit like a quadrupedal GEKKO...
