After a few long weeks of tinkering, I think Ive settled on a final design that I would like to display at the Toronto Hobby show.



This is a six leg walker, that uses the leg design of Theo Jansen

After seeing his video here

I spent some time learning about his 11 tube leg design. I found the best way to learn about this very neat leg concept is to build one. Once you have it, its a very stable, and repeatable leg. I have not found any good “how too” to make this leg. I spent a lot of time, re-playing clips and videos, and looking at Sim’s of the “TJ” leg.

I have some shots of the ‘bot here:

and a video of My walker here:

I want to thank Janey for being the Flame under my butt. Without her, or the twenty 7L axles, I would not have broght this walker to its finished state.


After I built the walker, I found a few other people have done this in lego as well:

(...) Chris, its simply amazing. One of the most elegant moving MOCs I have ever seen. Im blown away how great and streamline it looks and how smooth it functions. Oh yeah, and its kick butt CREEPY too. Totally love this MOC, by far, my most (...) (16 years ago, 19-Oct-07, to lugnet.org.ca.rtltoronto, FTX)

(...) Congratulations, Chris, you wonderfully captured the light and organic structure of Theo Jansen creations. Simply wonderful! Philo (16 years ago, 19-Oct-07, to lugnet.org.ca.rtltoronto, FTX)
  Re: Walker useing new leg design
 
As I wanted to play with your design (and if possible decrease the number of L7 axles still relatively scarce in my collection...), I modelled it using (URL) Euklides 2.02 geometry freeware>. (URL) Euklides file is (URL) here>. You can animate the (...) (16 years ago, 20-Oct-07, to lugnet.org.ca.rtltoronto, lugnet.technic, FTX)

(...) As Elmer Fudd would say, "That MOC wocks!";-) All seriousness aside, that is trés cool, Chris. Can't wait for Ross' reaction-- He'll flip out! It's funny; he's actually building a robot-thingy (I think that the technical term) right now as (...) (16 years ago, 20-Oct-07, to lugnet.org.ca.rtltoronto, FTX)

  Re: Walker useing new leg design
 
(...) ..and the best way to introduce someone to Theo Jansen's amazing mechanisms is to have someone build one out of common materials you have on hand (OK, I'm a little short of 7L axles as well, but that can be worked around). Really, this is (...) (16 years ago, 21-Oct-07, to lugnet.org.ca.rtltoronto)

(...) That's a very neat walker. I believe (URL) tractor> used a very similar mechanism, but I didn't bother to do a sketch. If you want to check it out yourself it's at the transport museum in Wetaskiwin Alberta. Or at least it was in 2001. I don't (...) (16 years ago, 22-Oct-07, to lugnet.org.ca.rtltoronto, FTX)
