Roz - Walking

So, we had a good time at CNRG last weekend. Roz, my new quad walker, came in second place in the walking competition. First place went to Mike Ferguson's Issy. You can see both of them, plus the third place finisher, in this video:

Roz was the first walker in that video, followed by Jeff, and then Issy. There's still lots of optimization to do with Roz...

I've also printed a new test leg that will have compliance - should be interesting to see how that affects things, and of course I'll have to figure out how to use this new-found capability once all the legs are done that way. To the right you can see the two parts, fresh out of the printer, with the support material still attached. As I type this, they are in the support bath removal tank.

On the mini-sumo front, Seeker 2x squeaked out with second place. First place honours went to Seeker 2, which was run by my son Nick. He won an Arduino experimenter's kit as his prize, which is pretty awesome. We also came away with a couple ArbotiX control boards, one of which is controlling Roz, and the other will be Nick's to allow him to play with Bioloids.


  • Your robot design was cool, but just wow at Izzy. Good to hear the 3d printer is working out well. Do you know any resources that describe the actual physical process of the printing method the uPrint uses? Not the use of the machine, but rather the application of plastic to create the layers.

  • Pretty cool. The other 2 had better leg motion, but I liked your algorithm better. Yours looked like it could deal with a different shaped hallway than the others. You could have coded yours to do just that first turn and not lost as much time correcting :)

  • Keith - if you look at a RepRap machine (or a MakerBot), you can figure it out. Those work pretty much the same as the uPrint - the only real difference is the uPrint has a dual print head, so it can do both material and support.

    Eric - yeah, my algorithm could definitely have been better, but I thought it was pretty good considering I coded it in my hotel room the night before...

  • more updates. What's the seeker up to? How are the legs progressing? Until I have a reprap and free time, I'm living vicariously through your blog (among others) thanks;)

  • The information about the walking robots given in this blog was really amazing. It was informative. Thanks for sharing.
