It looks you guys, are all quite excited about the pneumatics return... so I decided to give you a pneumatic overdose and highlight here today, both one automatic Hexapod and one automatic Octapod from robolegoenthusiast.
Amazing, isn't it?
I'm also a fan of the many Kevin Clague's [1, 2] pneumatic multi-leg bugs.
However many of their correspondent online videos, are not yet available from a content system suitable to make them embedded here. So I've just selected a few from those available, to give here a brief sneak of Kevin's creations too.
You may find a few more videos at his YouTube channel and a lot more detail about other pneumatic projects at his website (Kevin Clague's LEGO Page).
If you would like to initiate on automatic pneumatic sequencing techniques it may worth to take a reading on this other Kevin Clague's tutorial.
