  • It moves by initiating a fall forward, and recovers by dropping a foot in front. That suggests dynamics that would be upset by (need recalculating for) an environment with wind and/or viscosity like under water. Also what does it do if it falls and lands with one or more legs in the air?

  • The motion of the knee joint is dictaed by the tilt angle of the body by active control - only when needed. One student is working on standing up strategies - we have 4 ways of making it stand up, including one utilizing a dynamic whipping motion of one of it's legs.

  • It seems a flawed but promising design. In the video it show it (simulated) walking over rocks. Since the robot depends on falling forward to walk, what happens if the knee joint of the leg swinging forward hits something like a large rock or fallen tree? Would it trip over? Is it smart enough to cause itself to fall backward quickly to counter this stumble? Many questions unanswered indeed. Still, very cool.

  • Unlike STriDER 1.0, all joints of STriDER 2.0 are actuated to handle such cases using dynamic path planning of the swing leg foot. It still utilizes the concept of passive dynamic locomotion since the joint trajectories follow the path as if they were not actuated, thus still energy efficient.

  • This is so cool!

  • "And this Thing! How can I describe it? A monstrous tripod, higher than many houses, striding over the young pine trees and smashing them aside its wallowing career; a walking engine of glittering metal, reeling now across the heather, articulate ropes of steel dangling from it, and the clattering tumult of its passage mingling with the riot of the thunder." - War of the Worlds, H. G. Wells

  • Try f**king with us NOW, Martians! We're reverse-engineering all your precious technology from your Invasion of Victorian London!

  • neat

  • STRIIIIDEEERR!!!

  • It would have been nice if STriDER could get up when it falls or climb steep slopes or even swing in the branches of the trees. How about running or crawling?

  • So when do we put guns on them and make them giant? Half-Life 2 won't happen unless we all work hard for that goal!

  • War of the Worlds has never been more hilarious

  • All it needs now is a hub and a few lasers... Then we have a Martian War Machine!!!.

    So yeah thats pretty cool.

  • good gravy. in the demo video i was like, "Yeah right, that thing will never move like that!" Well, i ate my words...it tasted like...strider.
