    Re: SSClagorpion —Steve Hassenplug
   (...) Now, I have a question about the "logic" behind walking sideways. When SSClagorpion is done walking sideways, and it starts walking forward, will the legs all be in the same position in/out, or will 1/2 be in, while 1/2 are out? Assuming the (...)

   (...) Below is a diagram of the 8 legs as one of the two points where all eight feet are down. A\_ \B _/D C/ E\_ \F _/H G/ Assuming that all the hips sweeps are the same, for example compressed means swept backwards, and expanded means swept (...) (21 years ago, 4-May-04, to lugnet.technic)

     (...) ... (...) ... (...) Will it be possible to expand or contract all sideways walking pistons at the same time? Or is that like walking forward, where 1/2 will be expanded, while the other 1/2 are contracted? (21 years ago, 5-May-04, to lugnet.technic)
    
         Re: SSClagorpion —Kevin L. Clague
     (...) Looking at SSClagorpion from the front........ and only looking at one of the two leg groups: __ / / Down __ \ \ Down __ \ \ Up __ / / Up In this case we'll need to have half the sidways pistons expanded and half contracted all the time.

         Re: SSClagorpion —Steve Hassenplug
     (...) Right. I think. So, where (side to side) will the legs be when it's walking forward? (21 years ago, 5-May-04, to lugnet.technic)
    
         Re: SSClagorpion —Kevin L. Clague
     (...) Like this: __ / \ So when we stop walking sideways, we have to force all the sidewalking pistons to expand. You said this didn't you. Kevin (21 years ago, 5-May-04, to lugnet.technic)

        Re: SSClagorpion —Steve Hassenplug
   (...) slight problem. When SSClagorpion is walking sideways, due to the LEG SWEEP the legs will be positioned as show above. However, when he takes a step left, legs A, B, E & F would be stepping forward(up)/left and C,D,G & H are stepping (...) (21 years ago, 8-May-04, to lugnet.technic)
   
        Re: SSClagorpion —Kevin L. Clague
   (...) All along, I'd thought that it would zig/zag as it walks sideways, as you've noted. But I was wrong. A, D, E and H are in one leg group. This means that A, and E are walking forward/left, and D and H are walking backard/left. This means that (...) (21 years ago, 8-May-04, to lugnet.technic)

        Re: SSClagorpion —Steve Hassenplug
   (...) hmm. I didn't think about doing that. :) (...) Does that include the sideways_out_force? It may be about 8 switches short. But I don't think that matters. (...) Yes. I'm fine with that, also. Eric? (...) Looking at the totals on top, I think (...) (21 years ago, 9-May-04, to lugnet.technic)
